What will be the output of the program in 16 bit platform (Turbo C under DOS)?

#include<stdio.h>
int main()
 {
     int fun();
     int i;
     i = fun();
     printf("%d\n", i);
     return 0;
 }
 int fun()
 {
     _AX = 1990;
 }

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?

#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;
 }

4) What will be the output of the program?

#include<stdio.h>
int reverse(int);
int main()
{
     int no=5;
     reverse(no);
     return 0;
 }
int reverse(int no)
 {
     if(no == 0)
         return 0;
     else
         printf("%d,", no);
     reverse (no--);
 }

5) What will be the output of the program?

#include<stdio.h>
int fun(int);
int main()
 {
     float k=3;
     fun(k=fun(fun(k)));
     printf("%f\n", k);
     return 0;
 }
int fun(int i)
 {
     i++;
     return i;
 }
