C++ program that asks the user to enter his age in days
#include <iostream>
using namespace std;
void Findage() //Defining function
{
int a=0,d=0, m=0, y=0, r=0;
cout<<"Enter Age in Days= "; //Taking input
cin>>a;

r=a%365;
if(r>30)
{
m=r/30;
d=r%30;
}
else

d=a;
}
}if(a==365) //Printing output
{ cout<<"Your Age in Calender"<<endl;
cout<<"Year = 1"<<endl;

cout<<"Your Age in Calender"<<endl;
cout<<"Years= "<<y<<" Month="<<m<<" Days= "<<d<<endl;
}
}
int main()
{
Findage(); //Calling function
return 0;
}
Output
Enter Age in Days= 3697
Your Age in Calender
Years= 10 Month=1 Days= 17
A C++ program can be written to calculate a user's age in years, months, and days by dividing the total number of days provided by the user by 365 to find years and then dividing the remainder by 30 to calculate months, with the final remainder indicating the days.
A C++ program that calculates a user's age in years, months, and days from the age in days can be composed using simple arithmetic operations. Given that 1 year is 365 days, 1 year is 12 months, and 1 month is 30 days, the following process can be followed:
Ask the user for their age in days.
Use the remainder of the previous division to calculate the number of months by dividing by 30.
The remainder of the last division will give the number of days.
The resulting calculations will give the user's age in years, months, and days.
A final class can't be extended.
*True
*False
Answer:
The answer is True.
Explanation:
The final class cannot be extended because in java final keyword means "no modification". If it is applied to a variable or anything else then that value becomes a constant after that it cannot be modified.So in cases of class if final keyword is used it means that class cannot be extended.
Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10}, print: 7 9 11 10 10 11 9 7
Answer:
JAVA program to display the array elements both forward and backward is given.
public class MyProgram {
public static void main(String args[]) {
int len = 5;
int[] courseGrades = new int[len];
courseGrades[0] = 7;
courseGrades[1] = 10;
courseGrades[2] = 11;
courseGrades[3] = 9;
courseGrades[4] = 10;
System.out.println("The elements of array are ");
for(int i=0; i<len; i++)
{
System.out.print(courseGrades[i]+" ");
}
// new line is inserted
System.out.println();
System.out.println("The elements of array backwards are ");
for(int i=len-1; i>=0; i--)
{
// elements of array printed backwards beginning from last element
System.out.print(courseGrades[i]+" ");
}
// new line is inserted
System.out.println();
}
}
OUTPUT
The elements of array are
7 10 11 9 10
The elements of array backwards are
10 9 11 10 7
Explanation:
This program uses for loop to display the array elements.
The length of the array is determined by an integer variable, len.
The len variable is declared and initialized to 5.
int len = 5;
The array of integers is declared and initialized as given.
int[] courseGrades = new int[len];
We take the array elements from the question and initialize them manually.
First, we print array elements in sequence using for loop.
for(int i=0; i<len; i++)
To display in sequence, we begin with first element which lies at index 0. The consecutive elements are displayed by incrementing the value of variable i.
The array element is displayed followed by space.
System.out.print(courseGrades[i]+" ");
Next, we print array elements in reverse sequence using another for loop.
for(int i=len-1; i>=0; i--)
To display in reverse sequence, the last element is displayed first. The previous elements are displayed by decrementing the value of variable i.
At the end of each for loop, new line is inserted as shown.
System.out.println();
The length and elements of the array are initialized manually and can be changed for testing the program.
Loops are used to perform operations that would be repeated in a certain number of times; in other words, loops are used to perform repetitive and iterative operations
The loop statements are as follows:
for(int i = 0; i<sizeof(courseGrades)/sizeof(courseGrades[0]);i++){
cout<<courseGrades[i]<<" ";
}
cout<<endl;
for(int i=sizeof(courseGrades)/sizeof(courseGrades[0]) - 1; i >=0; i--){
cout<<courseGrades[i]<<" ";
}
cout<<endl;
The flow of the above loops is as follows
The first for loop prints the elements in a forward order.The second for loop prints the elements in a backward order.Read more about loops at:

After you create an array variable, you still need to ____ memory space.
a.
reserve
b.
create
c.
organize
d.
dump
Answer:
Answer is (a) reserve
Explanation:
Usually when we create an array variable, in some language the memory is allocated automatically. But in some the memory is not allocated automatically. So we need to reserve the memory space for the array.
For example in C++ dynamic memory allocation we need to allocate memory using new keyword.
Mergesort uses the divide-and-conquer technique to sort a list.
True
False
Answer:
True: Merge Sort sorts a list using divide-conquer approach.
Merge_Sort(B,p,n) //p is the starting index of array B and n is the last index.
1. if(p<n)
2. q ← (p+n)/2 //divides the list into two sub-lists
2. Merge_Sort(B, p, q) //sorts the left half
3. Merge_Sort(B, q+1, n) //sorts the right half.
4. Merge(B, p, q, n)
Merge(B, p, q, n)
1.l ← q-p+1. //no. of elements in left half
2.m ← n-q //no. of elements in right half.
3.for x ← 1 to l
4. Left[x] = B[p+x -1] //The elements of left half are copied to Left array
5.for y ← 1 to m.
6. Right[y]= B[q+y] //The elements of right half are copied to right array
7. x ← 1, y ←1
8.for z ← p to n.
9. if( Left[x] ≤ Right[y] ) // to merge the two lists Left and Right, the //elements are compared.
10. { A[z] ← Left[x] //smaller one comes to the merged list.
11. x++. }
12. else
13. { A[z] ← Right[y]
14. y++ }
Explanation:
The Merge_Sort(A, p, n) algorithm first divides the whole array into two halves. Then again divides the sub-lists into it's halves and so on.
Then using merge algorithm it compares the elements of both halves one by one and keep it in sorted order.
If the list above is named list1 and is implemented as a list, whatstatement would you use to find the number ofelements?list1.size()list1.numElementslist1.lengthlist1.contains
Answer:
list1.size()
Explanation:
In order to find the number of elements in a List , we can use the size() method defined in the java.util.List interface.
This method returns an integer which corresponds to the number of elements in the list.
The usage syntax example is as follows:
int num = list1.size();
If the list referenced by list1 contains 6 elements, then this method will return the value 6.

What is the output of the following code segment? int n = 0; for (int k = 0; k< 2; k++) {n=n +2;} cout << n; oo 0 1 O O O
Answer:
4
Explanation:
The loop is used to execute the part of code or statement again and again until a condition is not true.
syntax of for loop:
for(initialize; condition; increment/decrement){
statement;
}
in the question, the value of n is zero.
then, for loop check the condition k<2, initially the value of k is zero. so, the condition is true and execute the code n = 0 +2=2
Then, k is increment by 1. so, the value of k is 1.
then, again loop run and check the condition 1<2, it true. then n = 2+2=4.
then, k is increment by 1. so, the value of k is 2.
Then, again check the condition 2<2, condition false and program terminate the loop and finally print the value 4.

A while loop is somewhat limited, because the counter can only be incremented by one each time through the loop.
True False
Answer:
False
Explanation:
In a while loop we can increment the counter by any number that we wish. It is not that the counter can only be incremented by one each time through the loop.
Below is an example of a while loop with counter incremented by 5 each time.
int count=0; //initialize count to 0
while(count<50){ //continue the loop till count is lesser than 50
cout<<count; //display the value of count
count = count + 5; //increment counter by 5 each time
}
Final answer:
The statement is false; a while loop can increment a counter by any amount based on the code within the loop's body.
Explanation:
The statement that a while loop is limited because the counter can only be incremented by one each time through the loop is false. In programming, a while loop can be used to increment or alter a counter variable by any amount, as dictated by the statements within the loop's body. The control of a while loop is based on a condition, and as long as the condition remains true, the loop will continue to execute.
For example:
int counter = 0;
while (counter < 10) {
counter += 2; // Increment counter by 2
}
In this example, the counter variable starts at 0 and increases by 2 on each iteration of the loop. You can increment the counter by any number, or even apply other operations to change its value in complex ways.

Which of the following statements isNOT true about abstract data types (ADTs)?A list is anexample of an ADT.ADTs hide theimplementation details of operations from users.Java provides allthe ADTs you need, therefore you do not need to create any newones.An ADT is anabstraction of a commonly appearing data structure.
Answer:
Java provide all the ADTs you need,therefore you do not need to create any newones.
This statement is not true.
Explanation:
ADTs are those data types which we use but we didn't know their inner working that is how it is working what is happening inside.It is commonly used for Data Structures for example:- In stack we use push and pop operations to insert and to delete element from a stack respectively but we didn't know how it is happening inside.How the stack is implemented and etc.Java provides most of the ADT's but not all.
The statement that is wrong as regards abstract data types in this question is C: Java provides all the ADTs you need, therefore you do not need to create any new ones.
The abstract datatype can be regarded as special kind of datatype, whereby the behavior of the data is been defined by a set of values as well as a set of operations.ADTs can perform operation such as hiding of the implementation details of operations from users. It can be regarded as an abstraction of data structure that appear more oftenExamples of ADT are;
StackQueueListTherefore, option C is correct.

Write a C++ programthat reads in the side of a square and prints out a pattern on$
symbols representing thatsquare. The program should work for side sizes between
2 and 10. For example, ifa size of 4 is entered, the following output should be
produced:
$$$$
$$$$
$$$$
Answer:
#include<iostream>
using namespace std;
//main function
int main(){
//initialize the variables
int side;
//print the message
cout<<"Please enter the side of square: ";
cin>>side; //read the vale and store in the variable.
// for loop
for(int i=1;i<=side;i++){ //lop for rows
for(int j=1;j<=side;j++){ //loop for column
cout<<"$"; //print the '*'
}
cout<<endl;
}
}
Explanation:
Create the main function and declare the variable side.
print the message on the screen for the user and then store value enter by the user on the variable side.
take the nested for loop for print the pattern.
nested for loop means, loop inside another loop it is used for print the pattern having rows and columns.
the first loop updates the row number and the second the loop print the character '$' in the column-wise.
in the code,
if i = 1, for loop check the condition 1 <= 5 if the value of side is assume 5.
condition is true and the program moves to the second for loop and starts to print the character '$' five times after that, print the new line.
then, the above process repeat for different rows and finally, we get the pattern in square shape.

their names?
Answer:
Serial communication are connected using 2 types of connector
Explanation:
The two types of connector for serial communication are:
1. Nine pin connector.
2. Twenty five pin connector.
for 9 pin connector we have:
pin 1 = data carrier detect
pin 2= received data
pin 3= transmitted data
pin 4= data terminal ready
pin 5= signal ground
pin 6= data set ready
pin 7= request to send
pin 8= clear to send
pin 9= ring indicator
Here, the minimum number of pins can be pin 2,3 and 5 which are receive, transmit and ground signal to establish a communication without handshaking.
The minimum number of pins actually depend on the type of software we use.
