Answer:
#include<iostream>
using namespace std;
int digits(int number){
int sum=0;
while(number != 0){
int rem = number % 10;
sum = sum + rem;
number = number/10;
}
return sum;
}
int main(){
int number;
cout<<"Enter the integer: ";
cin>>number;
int result = digits(number);
cout<<"The sum of digits is: "<<result<<endl;
}
Explanation:
Include the library iostream for use of input/output.
Then, create the function digits with return type int.
Take a while loop and put a condition number not equal to zero.
the while loop executes the until the condition is not false.
In the while loop, take the remainder of the number and store in the rem variable.
after that, the store in the sum then reduces the number by dividing 10.
for example:
the number is 123.
rem = 123%10 it gives the value 3.
sum = 0+3=3
number = 123/10 it equal to 12
then,
rem = 12%10 it gives the value 2.
sum = 3+2=5
number = 12/10 is equal to 1
the same process executes until the number becomes zero and then the while loop terminates and the sum value returns to the main function.
create the main function and take the value from the user and call the function with the argument number.
and finally, print the result.

False
A spreadsheet is a collection of data organized into rows and columns. However, it has limitations compared to relational databases in terms of data organization and accessibility.
Explanation:A spreadsheet is a collection of data that is organized into rows and columns. Each column represents a field or attribute, while each row represents a record or data instance. While spreadsheets can function as a type of database, they have limitations in terms of data organization and accessibility compared to relational databases which use a tabular structure and allow for easier reorganization and access of data.
You can initialize more than one variable in a for loop by placing a(n) ____ between the separate statements.
a.
equal sign
b.
comma
c.
period
d.
semicolon
Answer:
comma
Explanation:
The for loop is used to execute the specific statement again and again until the condition is false.
The syntax:
for(initialization;condition;increment/decrement)
{
statement;
}
In the initialization, we an initialize more than one variable by using the 'comma' as separator.
similarly for condition and increment/decrement part as well.
for example:
for(int x = 0,y = 0;x<5,y<5;x++,y++)
{
statement;
}
we can used as many as possible by using comma
Define the following variables (in a new file and a new main() function):
• Integer value a and b
• Pointer variable p and q (pointers to integer values)
• Set the value of a to 5 and value of b to 7
• Set p to point to a and q to point to b (in other words assign the address of variables to pointers)
Answer:
#include<stdio.h>
int main()//driver function
{
int a=5;//initializing variable a
int b=7;//initializing variable b
int *p,*q;//declaring pointers p and q
p=&a;//assigning the address of a to p
q=&b;//assigning the address of b to q
printf("value of a is %d\n",a);
printf("value of b is %d\n",b);
printf("value of pointer p is %d\n",*p);
printf("value of pointer q is %d\n",*q);
printf("address of a is %d\n",&a);
printf("address of b is %d\n",&b);
return 0;
}
Output
value of a is 5
value of b is 7
value of pointer p is 5
value of pointer q is 7
address of a is -783856608
address of b is -783856604

When askingfor a raise, which one among the following is important toremember?
a- Effort is to berewarded
b- Non-cash benefits may beof value if a raise is not feasible
c- The length of employmentis a great bargaining tool in asking for araise
d- Emotional appeals canhelp in getting a positive response to therequest
Answer:
a-Effort is to be rewarded
Explanation:
When you ask for a raise in an organization,the one of the most important thing is Effort.There is a reason for everything in organization,if you are asking to raise your income organization will ask you on which basis you are asking.If you put extra hours than before or you gain some skill which is useful for the organization,so while asking for raise you should know the effort that you put in because effort is most important factor for a raise.
In formal organizations, Non cash benefits are not there so there is no purpose for asking it.
Employment does not matter for the peer in asking for a raise,sometimes it is used by small organizations but it is informal,the one should focus more on effort rather than the employment.
Emotional appeals may help in informal organization,never in formal organization.It only imprints negative image on peer's mind,if you want to have a raise you should focus on Effort.

write a program that convert binary number to decimal. I mean the input should be binary number and the output decimal number!!.
Answer:
#include<iostream>
#include<math.h>
using namespace std;
//main function
int main(){
//initialization
long b1;
int d1=0,count_pos=0;
//display the message
cout<<"Enter the binary number: ";
cin>>b1; //store the value
//loop for take the digit one by one
while(b1!=0){
int rem1 = b1%10;
d1 = d1 + rem1*pow(2,count_pos);
count_pos++;
b1 = b1/10;
}
//display the output
cout<<"The decimal number is: "<<d1<<endl;
}
Explanation:
Create the main function and initialize the variables. Then, display the message on the screen by using the instruction cout and then, store the input enter by the user into the variable. Here, the variable declares with type 'long' because of the size of the input.
After that, we take a while loop for splitting the binary number into the digits and then we can do the operation.
Let's understand how you can convert binary to decimal with an example:
let the binary number is 1001:
decimal number is [tex][tex]1*2^{3}+0*2^{2}+0*2^{1}+1*2^{0}=9[/tex][/tex]
we put the same algorithms in the code. split the number into digit and then multiply with n raised to the power of 2 here, n is the position of digit from left to right.
NOTE: Position starts from zero.
and then, add the values. this process continues until the number is not zero.
After that, display the output on the screen.
: Differentiate between serial and parallel data transfer withat least one example of each from computer sciencedomain.
Answer:
In serial communication transfers one bit of data at a time, while parallel communication transfers many bits of data at the same time. Serial communication transmits the data bits sequentially, while parallel communication transmits data bits simultaneously, allowing greater amounts of data to be transferred.
-Serial communication is the one used to communicate the Arduino with the Computer through the USB cable.
-An example of a parallel port is the printer port. The Parallel Port was only created and used in the printers interface and the computers.
Explanation:
In serial communication, each bit is sent by its own clock flank where conditions are defined after each byte, if it is synchronous or asynchronous. In parallel communication there is only one single clock flank where the information is sent where it is an advantage to use it where there are several input or output data.

The exponent in floating point is stored as a biased value.
Answer:
True
Explanation:
The bias value present in a floating point number deals with the positiveness and negativeness of the exponent part for a floating point number. The bias value for a floating point number is 127. It means that 127 is always needed to be added to the exponent part of any floating point number.
In a single precision floating point number, we need 8 bits to store the exponent. Rather than storing it as a signed two's complement number, it is easier to simply add 127 to the exponent (because the lowest value that can be in 8 bit signed is -127) and simply store it as an unsigned number. If the stored value is bigger than the bias then it would mean the value of the exponent is positive otherwise it is negative, but if they are equal then it is 0.
The ____ method takes a String argument and returns its double value.
a.
parseString()
b.
returnDouble()
c.
parseInt()
d.
parseDouble()
Answer:
d
Explanation:
In java you can use pareDouble(string str) to convert the string into double.
for example if you have string like this.
string str = [tex]"16.45" ;[/tex]
then you can use
double mydouble = Double.parseDouble(str);
print(mydouble); //it will print out 16.45
but if the string would not be able to be parsed into double then you will get an error.
The expression vecCont.empty() empties the vector container of all elements.
True
False
Answer:
False
Explanation:
Vector is a similar to dynamic array which has the ability to resize itself automatically.
empty() is a function used in the vector.
It is used to check the vector is empty or not.
it does not delete the element in vector, it just check the vector is empty or not, if vector empty it gives a Boolean value True other wise False.
Therefore, the answer is False.
Given a int variable named callsReceived and another int variable named operatorsOnCall write the necessary code to read values into callsReceived and operatorsOnCall and print out the number of calls received per operator (integer division with truncation will do).
// c++ code to read the recieved calls
cout<< " Enter the calls recieved :";
cin>>callsRecieved;
cout<< " Enter operator on call : ";
cin>>operatorsOnCall;
// calculating the call per operator
calls_per_operator = callsRecieved/operatorsOnCall;
// printing the vaule.
cout<<" Calls recieved per operator are : " << calls_per_operator <<endl;
Final answer:
To find the number of calls received per operator, read inputs for callsReceived and operatorsOnCall, then divide callsReceived by operatorsOnCall using integer division and print the result.
Explanation:
To calculate the number of calls received per operator, you will first need to read values into the variables callsReceived and operatorsOnCall. You can do this using an input method appropriate for the programming language you're using (e.g., scanf in C, cin in C++, or input() in Python). Once you have these values, you perform the division of callsReceived by operatorsOnCall and print the result. Here is an example code snippet in Python:
# Read the number of calls received and the number of operators on callNote that integer division with truncation is used (// in Python) to get an integer result.
_________ local variables retain their value between function calls.
Answer: static
Explanation:
variables when declared static gets called statically meaning whenever a function call is made it get stored and it is not required to get the variable again when the function is again called. There scope is beyond the function block
A jeweler designing a pin has decided to use five stones chosen from diamonds, rubies, and emeralds. In how many ways can the stones be selected?
Answer:
3,125 different possible ways
Explanation:
Great question, hopefully i can shed some light on the situation. There are a total of 5 stones. One by one they are randomly picked out of the bag. We need to find how many possible combinations there are for picking the stones out of the bag. We can solve this by raising the amount of stones in the bag to its own power like so,
[tex]5^{5} = 3,125[/tex]
So now we can see there are 3,125 different possible ways of selecting the stones.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

1) All the elements of an array in Java MUST conform to the same data type.
a) True
b) False
Answer:
TRUE
Explanation:
The array is allow to store the multiple values but with same data type.
It cannot store element with different data type.
For example:
int array[] = {1, 'b', 8.7, 9, 'z'}
the above is wrong way to declare the array.
the correct ways is:
int array[] = {1,2,3,4};
float array[] = {1.2, 3.4, 9.6};
we can store only same data type element in multiple tiles.

Write a Java program that calculates and prints the monthly pay check for an employee. The net pay is calculated after taking the following deductions:
Federal Income Tax: 15%
State Tax: 3.5%
Social Security Tax: 5.75%
Medicare/Medicaid Tax: 2.75%
Pension Plan: 5%
Health Insurance: $75.00
Final answer:
A Java program can calculate an employee's net pay by deducting federal, state, Social Security, Medicare/Medicaid taxes, pension plan contributions, and health insurance costs from the gross pay. The net pay is then output as the amount the employee would receive in their paycheck.
Explanation:
To calculate the net pay for an employee after deductions, we need to write a Java program that considers the following deductions: Federal Income Tax at 15%, State Tax at 3.5%, Social Security Tax at 5.75%, Medicare/Medicaid Tax at 2.75%, a pension plan deduction at 5%, and a fixed amount for health insurance at $75.00.
Here is a simple example of how this Java program might look:
public class PaycheckCalculator {
public static void main(String[] args) {
double grossPay = 5000; // Example gross pay
double federalTax = grossPay * 0.15;
double stateTax = grossPay * 0.035;
double socialSecurityTax = grossPay * 0.0575;
double medicareTax = grossPay * 0.0275;
double pensionPlan = grossPay * 0.05;
double healthInsurance = 75;
double netPay = grossPay - (federalTax + stateTax + socialSecurityTax + medicareTax + pensionPlan + healthInsurance);
System.out.println("Net pay: $" + netPay);
}
}
This program calculates each of the deductions based on the gross pay, subtracts them from the gross pay, and prints out the resulting net pay.
