In the following program add a statement in the function fact() such that the factorial gets stored in j.

#include<stdio.h>
void fact(int*);

int main()
{
    int i=5;
    fact(&i);
    printf("%d\n", i);
    return 0;
}
void fact(int *j)
{
    static int s=1;
    if(*j!=0)
    {
        s = s**j;
        *j = *j-1;
        fact(j);
        /* Add a statement here */
    }
}

Are the expression *ptr++ and ++*ptr are same?

Will the program compile?

#include<stdio.h>
int main()
{
    char str[5] = "IndiaBIX";
    return 0;
}

The following program reports an error on compilation.

#include<stdio.h>
int main()
{
    float i=10, *j;
    void *k;
    k=&i;
    j=k;
    printf("%f\n", *j);
    return 0;
}

Are the three declarations char **apple, char *apple[], and char apple[][] same?

Is there any difference between the following two statements?
char *p=0;
char *t=NULL;

Is this a correct way for NULL pointer assignment?
int i=0;
char *q=(char*)i;

Is the NULL pointer same as an uninitialised pointer?

Will the program compile in Turbo C?

#include<stdio.h>
int main()
{
    int a=10, *j;
    void *k;
    j=k=&a;
    j++;
    k++;
    printf("%u %u\n", j, k);
    return 0;
}

Will the following program give any warning on compilation in TurboC (under DOS)?

#include<stdio.h>

int main()
{
    int *p1, i=25;
    void *p2;
    p1=&i;
    p2=&i;
    p1=p2;
    p2=p1;
    return 0;
}
