Code for reversing the digits of a given integer

Recently while browsing and I found one interesting question to reverse the digit of given integer. I thought to solve the same.

Solution is quite simple then I initially thought. Following is my solution.

    
    int origNum = 12304;
    int reverseNum = 0;

    while( origNum != 0) {
        int lastDigit = origNum % 10;
        origNum /= 10;
        reverseNum = reverseNum * 10;
        reverseNum = reverseNum + lastDigit;
    }

    printf("reverse number %d", reverseNum);
