a few problems that i dont have time to do, should take less than 1min per for a pro. pm me answers and u get 10fg each.


9)
#include<stdio.h>
void main(){
if('\0');
else if(NULL)
printf("a");
else;
}

10)
#include<stdio.h>
void main(){
int a=5,b=10;
clrscr();
if(a<++a||b<++b)
printf("%d %d",a,b);
else
printf("Can you reach me here?");
}

11)
#include<stdio.h>
void main(){
int x=1,y=2;
if(--x && --y)
printf("x=%d y=%d",x,y);
else
printf("%d %d",x,y);
}

12)
#include<stdio.h>
void main(){
signed int a=-1;
unsigned int b=-1u;
if(a==b)
printf("1");
else
printf("2");
}

13)
#include<stdio.h>
void main(){
char c=256;
char *ptr="ZANE";
if(c==0)
while(!c)
if(*ptr++)
printf("%+u",c);
else
break;
}

14)
#include<stdio.h>
void main(){
int a=2;
if(a--,--a,a)
printf("1");
else
printf("2");
}

What exactly is an answer? Text printed to stdout?

Anyway,


is not correct portable C, although it might be correct on some machines. It definitely isn't for x86 linux or windows.

9) Will print nothing.

10) Won't compile. If clrscr reference is removed, it's still undefined behaviour.

11) 0 2

12) 1

13) May be undefined behaviour, depending on platform (signed overflow).
On x86, the expected result would be:
0000

14) 2
