C++ Code to Reverse a Number

Reverse a Number using C++

#include <iostream>

int main() {

int a, b, c = 0;

// input a whole integer

// for example: 2485

std::cin >> b;

// for input failure

if( std::cin.fail() ){

std::cerr << "Wrong input!\n";

return 1;

}

std::cout << "Your number input : " << b << std::endl;

// reverse the input

while (b != 0){

a = b % 10;

c = ( c * 10 ) + a;

b = b / 10;

}

// output the reverse

std::cout << "The reverse number: " << c << std::endl;

return 0;

}
