What will be the output of the program ?


#include<stdio.h>
int main()
{
int i=2;
printf("%d, %d\n", ++i, ++i);
return 0;
}
Options:
A .  3, 4
B .  4, 3
C .  4, 4
D .  Output may vary from compiler to compiler
Answer: Option D

The order of evaluation of arguments passed to a function call is unspecified.



Anyhow, we consider ++i, ++i are Right-to-Left associativity. The output of the program is 4, 3.


In TurboC, the output will be 4, 3.


In GCC, the output will be 4, 4.
