/* This program is giving me output 8, I don't know how it is possible. I am using Turbo C++ complier.. Please Explain it to me */

#include<stdio. h>
void main()
{
int a,b=2;
a = (++b)+(++b);
printf("%d",a);
}

Output: 8

8 is as good as anythig else. Modifying a variable more than once in a C++ statement produces indeterminate results since the compiler if free to evaluate the variable in any order.
