Hi all,
Im compiling the code bellow for x86 with gcc 4.4.3 and 4.5. Is it correct
that at the end of main the value of variable b should have been 4? When 
executing I get value 3. 

#include "stdio.h"
int *ptr;

int inc(void){
    (*ptr)++;    
    return 1;
}

int main (void){
int a, b = 2;
ptr = &b;
b++ +  inc() ;
    
if(b==4)
    printf("correct\n");
else
    printf("incorrect %d\n",b);
return 1;
}
