Program

#include<iostream>
using namespace std;
int reverseInt(int num)
{
    int remainder,rev=0;
    do
    {
        remainder=num%10;
        rev=rev*10+remainder;
        num/=10;
    }while(num>0);
    return rev;
}
int main()
{
    int num;
    cout << "Enter an Integer: ";
    cin >> num;
    cout << "Reversed Number: " << reverseInt(num);
    return 0;
}

Output

$ g++ reverse-integer-number-using-do-while.cpp 
$ ./a.out
Enter an Integer: 987456321
Reversed Number: 123654789
