Which of the following statements are correct about the function?

long fun(int num)
 {
     int i;
     long f=1;
     for(i=1; i<=num; i++)
         f = f * i;
     return f;
 }

2) What will be the output of the program?

#include<stdio.h>
int addmult(int ii, int jj)
 {
     int kk, ll;
     kk = ii + jj;
     ll = ii * jj;
     return (kk, ll);
 }
int main()
 {
     int i=3, j=4, k, l;
     k = addmult(i, j);
     l = addmult(i, j);
     printf("%d, %d\n", k, l);
     return 0;
 }

3) Point out the error in the program

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

4) What will be the output of the program?

#include<stdio.h>
int main()
 {
     void fun(char*);
     char a[100];
     a[0] = 'A';
 a[1] = 'B';
     a[2] = 'C';
 a[3] = 'D';
     fun(&a[0]);
     return 0;
 }
 void fun(char *a)
 {
     a++;
     printf("%c", *a);
     a++;
     printf("%c", *a);
 }

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;
 }
