8.
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 */
}
}

Everything's more or less good, except that the factorial will be stored in i. After function call j will be destroyed.

The answer won't be 120 since s is static.
The answer will always be 0 you can copy this code in your compiler.

Why can I store the address of s in j? I also access the value of s through j because it store the address of s;

*j = &s means store the s address.
*j = s means store the s value.
*j = s means store the s value.

Please explain difference between *j=&s, *j=s.

@Udam: Same doubt here! Also, after each return from recursion, that value of s in the stack shall be copied to *j right?

Why j=&s is not workings?
