Read an integer from keyboard and then print the result of the sum obtained by adding the entered integer to the integer formed by reversing the order of the digits. (For example: entered number = 123. Sum = 123+321 = 444)

Following are the program in C+ + language

#include / / header file

using namespace std; / / namespace std;

int main () / / main function

{

int number, n1, rem; / / variable declaration

int sum, sum1=0; / / variable declaration

cout<<"Enter the number : ";

cin>>number; / / Read the number

n1=number; / / initialized the value of number with the n1

while (n1>0) / / iteating the while loop

{

rem=n1%10; / / finding the reminder

sum1=10*sum1+rem; / / storing the sum

n1=n1/10;

}

sum=sum1+number; / / calculate the sum

cout<<"The sum is:"<
return 0;

}

Output:

Enter the number : 123

The sum is:444

Explanation:

Following are the Description of the Program

Read the value of "number" in the "number" variable of int type. Initialized the value of "number" in the "n1' variable. Iterating the while loop until the n1>0. In this loop we reverse the number in the "sum1" variable Finally print the sum in the "sum" variable
