Reply:
#include<conio.h>
Non-standard header.
#include<stdio.h>
void main()
Non-standard definition of main, it should always return int.
{
int a=13,b,c;
b=++a + ++a;
printf("%i",b) ;
getch();
Non-standard function, and is also redundant (I hate it when programs wait
for me to press a button instead of giving back the control to the console).
}
ANS: b=30.
Your program shows what on your compiler the 'undefined behavior' does. It
proves nothing.
What's your point?
