Q1:

What will be the output of the program?

#include<stdio.h>
#include<stdarg.h>
void fun1(char, int, int *, float *, char *);
void fun2(char ch, ...);
void (*p1)(char, int, int *, float *, char *);
void (*p2)(char ch, ...);

int main()
{
    char ch='A'; int i=10;
    float f=3.14; char *p='Hello';
    p1=fun1;
    p2=fun2;
    (*p1)(ch, i, &i, &f, p);
    (*p2)(ch, i, &i, &f, p);
    return 0;
}
void fun1(char ch, int i, int *pi, float *pf, char *p)
{
    printf('%c %d %d %f %s \n', ch, i, *pi, *pf, p);
}
void fun2(char ch, ...)
{
    int i, *pi; float *pf; char *p;
    va_list list;
    printf('%c ', ch);
    va_start(list, ch);
    i = va_arg(list, int);
    printf('%d ', i);
    
    pi = va_arg(list, int*);
    printf('%d ', *pi);
    pf = va_arg(list, float*);
    printf('%f ', *pf);
    p = va_arg(list, char *);
    printf('%s', p);
}
