#include<stdio.h>
int main()
{
    int firstNo = 2, secondNo = 4;
    firstNo = firstNo + secondNo;
    secondNo = firstNo - secondNo;
    firstNo = firstNo - secondNo;
    //Value of firstNo and secondNo swapped
    printf("fisrtNo=%d",firstNo);
    printf("\nsecondNo=%d",secondNo);
    return 0;
}

Output:

fisrtNo=4
