int main()
 {
     int i=0;
     i++;
     if(i<=5)
     {
         printf("Study2Online");
         exit(1);
         main();
     }
     return 0;
 }

2) Point out the error in the program

#include<stdio.h>
int f(int a)
 {
   a > 20? return(10): return(20);
 }
int main()
 {
     int f(int);
     int b;
     b = f(20);
     printf("%d\n", b);
     return 0;
 }

3) Point out the error in the program

   f(int a, int b)
 {
     int a;
     a = 20;
     return a;
 }
