#define x 5+2 
int main(){     
int i;     
i=x*x*x;     
printf("%d",i);      
return 0;  
} 

main() 
{ 
xyz: goto abc;
printf("Hello"); 
abc: printf("World");
goto xyz;
}

int f(int a, int b); 
void main() 
{
int a = 12, b=154; 
printf("%d", f(a, b)); 
}
int f(int a, int b) 
{
if (a<b) return(f(b, a));
if(b==0) return(a);
return (f(b, a % b));
}

void change (char *k) 
{
k="Hello";
return; 
} 
main() 
{ 
char *ch = "World";;
change(ch); 
printf("%s", ch); 
}
