Thread: A lil confused

Need to know how the following code would function...

Code:

#include<stdio.h>
int main()
{
int i=7;
printf("%d",i++*i++);
}

for the above mentioned the output is 56
if i were to change it to

Code:

printf("%d",i++*i)

still the same output

Code:

printf("%d",++i*i++)

outputs it as 64

Cant figure out how its going about executing the statement, would appreciate help on this.
