Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
C++ Program To Reverse A Number Using While And For Loop
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int num, rev = 0;
//Reading a number from user
cout<<"Enter any number:";
cin>>num;
//finding reverse number using while loop
while (num > 0) {
rev = rev * 10;
rev = rev + num % 10;
num = num / 10;
}
cout<<"Reversed number is: "<<rev;
return 0;
}
Reverse a Number using for loop
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
int num, rev = 0;
//Reading a number from user
cout<<"Enter any number:";
cin>>num;
//finding reverse number using for loop
for (rev = 0; num > 0; num = num / 10) {
rev = rev * 10;
rev = rev + num % 10;
}
cout<<"Reversed number is: "<<rev;
return 0;
}
Result
