int check (int, int);
int main()
 {
     int c;
     c = check(10, 20);
     printf("c=%d\n", c);
     return 0;
 }
 int check(int i, int j)
 {
     int *p, *q;
     p=&i;
     q=&j;
     i>=45 ? return(*p): return(*q);
 }

2) If int is 2 bytes wide.What will be the output of the program?

#include <stdio.h>
void fun(char**);
int main()
 {
     char *argv[] = {"ab", "cd", "ef", "gh"};
     fun(argv);
     return 0;
 }
void fun(char **p)
 {
     char *t;
     t = (p+= sizeof(int))[-1];
     printf("%s\n", t);
 }

3) What will be the output of the program?

     fun(a);
     return 0;
 }
void fun(int n)
 {
     if(n > 0)
     {
         fun(--n);
         printf("%d,", n);
         fun(--n);
     }
 }
