Pointers2

#include <stdio.h>
#include <stdlib.h>
 
int main()
{
    char *a;
 
    a = (char *) malloc (sizeof(char));
 
    *a = 48;
 
    //fprintf(stdout, "*a is %c\n", *a);
 
    return(0);
}

Questions

If we uncomment that fprintf() line, what will be displayed?
What is malloc() doing?
Why is it needed?
