The simplest statement you can use to make a decision is the if statement. Thus, option C is correct.
What is a statement?A statement within a programming language is just a syntactic construct of an arbitrary programming language that also expresses a course of action. A series of one or more statements make up a program built in this language. There could be internal parts to a proposition.
The simplest illustration of a decision framework in Java seems to be the if statement. A conceptual test that can result in a positive or negative outcome is expressed in an if statement.
The if statements inside the if the branch were carried out if the test's outcome is true. In this case, the statement can either be true or the statement can either be false depending upon the condition.
Therefore, option C is the correct option.

What is the output of the following function call? //function body int factorial(int n) { int product=0; while(n > 0) { product = product * n; n❝; } return product; } //function call cout << factorial(4);
Answer:
zero
Explanation:
Because of the define the product variable is zero.
when the function call with pass by value 4.
The program control moves to that function, after that product
store the value zero. Then, product is multiply with n which become zero
because 0 * n is zero and store in the product again.
after that, n'' is wrong it must be 'n--' for performing the factorial function.
after that, the value of n is 3, again loop execute because condition n > 0
is true.
again zero multiply with n and become zero.
this process repeated until condition false and finally the output is zero.
Correction:
To make the code working:
change product = 1 instead of zero.
and change n-- in place of n''.

rite a program that prompts the user to enter an integer and displays each of its numbers one by one.
Answer:
#include <iostream>
using namespace std;
int main()
{
int num;
cout<<"Enter the integer: ";
cin>>num;
while(num>0){
int rem = num%10;
cout<<rem<<endl;
num = num/10;
}
}
Explanation:
First include the library iostream in the c++ programming for input/output.
Then write the main function and declare the variable.
cout is used to display the message on the screen.
cin is used to store the value in the variable.
then used the while loop and put the condition num>0
after that, take the reminder of the number by using the operator modulus '%'.
and then print it on the screen.
after that reduce the number by one digit.
This process continue until the condition not failed.
Therefore, the all digits of the number will be printed.

What are the modes of operation of WLANs?
Answer:
WLAN's or Wireless LAN Units have 2 main modes of operation
Explanation:
The Two Main modes of Operation are the following
Infrastructure Mode: in this mode the main WLAN unit becomes the main connection point in which all devices are connected to and the main unit provides an internet connection to all the devices connected to it.
Ad Hoc Mode: in this mode devices transfer data from one another back and forth without permission from a base unit.
Some WLAN units will also include 2 extra modes of operation called Bridge and Wireless Distribution System (WDS).
Bridge Mode: this mode allows the base unit to act as an intermediary and bridge two different connection points. Such as bridging a wired connection with a wireless one.
WDS Mode: this mode uses various access points to wirelessly interconnect devices to the internet using repeaters to transmit connections. It can provide internet to both wired and wireless clients.

. Two or more functions may have the same name, as long as their _________ are different.
Answer:
Number of parameters.
Explanation:
The function is a block of the statement which performs the special task.
Syntax:
type name(parameter_1,parameter_2,...){
statement
}
we can define any number of function in the code and also with the name as well.
But when we define the function with same name the number of parameter define in both function must be different.
for example:
1. int print(int a){
statement;
}
2. int print(int a, int b){
statement;
}
first has one parameter and second has two parameters.
Both are valid in the code.
Write a program that will compare two names. The program prompts the user to enter two names for a comparison. If the names are same, the program states that. If the names are different, the program converts both names to UPPERCASE, and compares then again. If they are equal, the programs displays a message stating that names are equal if CASE is ignored. Otherwise, the program prints names with a message that names are not equal.
Answer:
We can use comparison operator 'Equals to' (==) to compare two strings.
Explanation:
We can use conditional statement 'if else' to put conditions. If statement contains boolean expression.If statement is followed by else block. If the boolean expression evaluates to true, then the if block of code is executed, otherwise else block of code is executed.
If we want to compare two strings with uppercase, then we can convert the input strings given by users using ToUpper() string function.
For example,
string abc;
string uppercase= abc.ToUpper(); // gives ABC as result

Implement RandMultipByVal function, which gets one integervariable as its argument
and multiply it by a random number between 1 to10 (use call-by-value approach).
Answer:
#include <iostream>
#include <stdlib.h>
#include <time.h>
using namespace std;
void RandMultipByVal(int number){
srand(time(NULL));
int random = rand()%10+1;
cout<<random*number;
}
int main()
{
RandMultipByVal(4);
return 0;
}
Explanation:
Include the three libraries, iostream for input/output, stdlib.h for rand() function and time.h for srand() function.
Create the function with one integer parameter.
Then, use srand() function. It is used to seed the rand() function or locate the starting point different in different time.
rand(): it is used to generate the random number between the range.
for example:
rand()%10 it gives the random number from 0 to 9.
if we add 1, then it gives from 1 to 10.
After that, multiply with parameter value and then print the result.
For calling the function create the main function and call the function with pass by value.
the address of the last cell of a memory RAM is 3FFFFh.a total capacity of the main memory and 4M bits and the data bus can transfer the contents of two memory cells , respond
a)which register the size of the memory address(MAR) ?
b)where the maximum number of cells that can be stored in memory?
c)which the cell size of this machine ?
d)which the size of the memory buffer register (MBR ) ?
Hey there!:
Given the address of the last cell of a memory RAM is 3FFFFh then :
There are 8 bits in a byte
1024 bytes in a kilobyte
so 8*1024= 8192
so 8192 bits in a kb
32*8192 = 262144
there are 262144 bits in 32KB .
a) 32 bit address registers must match 2^32 byte = 4 GB of physical memory.
However, with 32 Bit you can also address more than 4 GB, like Physical Address Extension (PAE) does.
The other way is that you can access 4 GB with less than 32 bit address register.
____________________________________________________
b) Main Memory = 4M × 32Kbits, RAM chips = 32K × 4bit.
For this memory we require 4 × 2 = 8 RAM chips.
Each chip requires 18 address bits (ie. 218 = 256K).
And 1M × 8 bits requires 20 address bits (ie. 220 = 1M )
_____________________________________________________
c) The size of the storage cells is known as the word size for the computer.
In some computers, the word size is one byte while in other computers the word size is two, four, or even eight bytes. In our 4M main memory the size of cell is 4*2^20 bytes.
Each storage cell in main memory has a particular address which the computer can use for storing or retrieving data.
______________________________________________________
d) The size of MBR is the 4M bits of main memory.

Hope this helps!
True of False - use T or F The Throwable class implements the Serializable interface
Answer:
T
Explanation:
The java.lang.Throwable class implements the Serializable interface.
If a class implements an interface then all its subclasses also implicitly implement the interface.
Note that all Exception classes in Java inherit from java.lang.Throwable. Since Throwable is Serializable, by implication, all java Exception classes are also Serializable by default. That is, all exception classes can be serialized to a file or sent over the network is required.
Write a c++ program to compute a water andsewage bill. The inputis the number of gallons consumed. The bill is computed asfollows:
water costs .21dollars per gallon of water consumed
sewage service .01dollars per gallon of water consumed
Answer:
#include<iostream>
using namespace std;
//main function
int main(){
//initialization
float gallonConsume;
//print the message
cout<<"Enter the number of gallons consumed: ";
cin>>gallonConsume; //read the input
float waterCost = 0.21 * gallonConsume; //calculate the water cost
cout<<"The water cost is: "<<waterCost<<endl; //display
float sewageService = 0.01 * gallonConsume; //calculate the sewage service cost
cout<<"The sewage service cost is: "<<sewageService<<endl; //display
return 0;
}
Explanation:
Include the library iostream for using the input/output instruction.
Create the main function and declare the variables.
then, print the message on the screen by using cout instruction.
the value enters by the user is read by cin instruction and store in the variable.
After that, calculate the water cost by using the formula:
[tex]Water\,cost = 0.21 * water\,consume[/tex]
then, display the output on the screen.
After that, calculate the sewage service cost by using the formula:
[tex]sewage\,service\,cost = 0.01*water\,consume[/tex]
finally, display the output on the screen.

Comparison between Sendmail vs. Qmail
Answer: Sendmail and Qmail are the mail transferring agents which carry out the process of sending the mail. they also have differences between them .
Explanation: Comparison between sendmail and Qmail are as follows:-
There is less security aspect in the sendmail as compared to the Qmail which was created to overcome this issue.Qmail has faster execution and other features as compared with the sendmail.Sendmail is not highly reliable whereas Qmail has got a good reliability factor. Send mail has bigger components which make it complex and slow as compared with Qmail which has small component.True of False - use T or F The Math class can be instantiated.
Answer:
F
Explanation:
The Math class cannot be instantiated because it has a private constructor.
However all the methods in the java.lang.Math are static which means that you can invoke them directly without having to instantiate the class. For example:
static int abs(int a) defined in the Math class can be invoked from the calling function as:
int absolute_value = Math.abs(a);
Note that the class Math is also declared as final which means it cannot be extended by any other class as well.

Explanation:
Which of the following would compile without error? A. int a = Math.abs(-5); B. int b = Math.abs(5.0); C. int c = Math.abs(5.5F); D. int d = Math.abs(5L);
Answer:
int a = Math.abs(-5)
Explanation:
Math.abs() is the function which gives the absolute value of the integer.
syntax:
Math.abs(int name);
the argument enter must be integer(int).
int b = Math.abs(5.0): here, 5.0 is not the integer, it is float. So, it gives error.
int c = Math.abs(5.5F): here, 5.5F is not the integer, it is float. So, it gives error.
int d = Math.abs(5L): L stand for long but it is not int. So, it also gives error.
Therefore, the correct result is int a = Math.abs(-5), -5 is integer.
2) What is the value stored in the variable z by the statements below?
int[ ] q = {3, 2, -2, 4, 7, 0, 1};
int z = q.length;
a) 1
b) 3
c) 6
d) 7
e) None of the above
Answer:
7
Explanation:
Because the q.length is a inbuilt function in the programming which used to get the length of the array. In the array, there are 7 values are store. Therefore, the size 7 store in the variable z.
For example:
int[] array={1,2};
int x = array.length;
the answer of above code is 2, because the elements present in the array is 2.
