2) How many times the program will print "Study 2 Online" ?

  #include<stdio.h>
  int main()
 {
     printf("Study 2 Online");
     main();
     return 0;
 }

3) What will be the output of the program?

#include<stdio.h>
int main()
 {
     int fun(int);
     int i = fun(10);
     printf("%d\n", --i);
     return 0;
 }
int fun(int i)
 {
    return (i++);
 }

4) 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);
 }

5) What will be the output of the program?

#include<stdio.h>
int check(int);
int main()
 {
     int i=45, c;
     c = check(i);
     printf("%d\n", c);
     return 0;
 }
int check(int ch)
 {
     if(ch >= 45)
         return 100;
     else
         return 10;
 }
