This code gives me result 14. But I hope that result will be 12. so Why did this program give me this result?

What I have tried:

#include <stdio.h>

int main()
{
int i = 5;
int a = ++i + ++i;
printf("%d",a);

return 0;
}

This code:
C++
int a = ++i + ++i;

is in a gray zone, this means that the result is unpredictable and will depend on how it is handled by compiler. Result can be 12, 13 or 14.
Advice: Never do multiple increment/decrement on same variable in a formula.
