What will be the output of the program?

#include<stdio.h>
int i;
int fun1(int);
int fun2(int);

int main()
 {
     extern int j;
     int i=3;
     fun1(i);
     printf("%d,", i);
     fun2(i);
     printf("%d", i);
     return 0;
 }
int fun1(int j)
 {
     printf("%d,", ++j);
     return 0;
 }
 int fun2(int i)
 {
     printf("%d,", ++i);
     return 0;
 }
 int j=1;

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) What will be the output of the program?

#include<stdio.h>
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);
 }

4) What will be the output of the program?

#include<stdio.h>

 {
     int k=35;
     k = func1(k=func1(k=func1(k)));
     printf("k=%d\n", k);
     return 0;
 }
 int func1(int k)
 {
     k++;
     return k;
 }

5) What will be the output of the program?

#include<stdio.h>
