This C program is designed to compute the factorial of a user-entered integer. The program employs a `for`

loop to calculate the factorial and then displays the result. The user can continue inputting positive integers to obtain their factorials until a non-integer input is provided which terminates the program.

```
#include <stdio.h>
int fact(int n);
int main(void) {
int current;
printf("Enter a positive integer [to terminate enter non-positive] > ");
scanf("%d", ¤t);
while (current > 0) {
printf("The factorial of %d is %d\n", current, fact(current));
printf("Enter a positive integer [to terminate enter non-positive] > ");
scanf("%d", ¤t);
}
return 0;
}
/* n is a positive integer. The function returns its factorial */int fact(int n) {
// loop control variable
int lcv;
// set to the product of the first lcv positive integers
int p;
for (p = 1, lcv = 2; lcv <= n; p = p * lcv, lcv++);
return p;
