Q2:
Point out the error if any in the following program (Turbo C). 
#include<stdio.h>
#include<stdarg.h>
void display(int num, ...);

int main()
{
    display(4, 'A', 'a', 'b', 'c');
    return 0;
}
void display(int num, ...)
{
    char c; int j;
    va_list ptr;
    va_start(ptr, num);
    for(j=1; j<=num; j++)
