If I wanted to improve this program that would allow me to enter larger integers than 10, what would I do. I think I would use long. Any help or ideas??
#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);
}
}
/* n is a positive integer. The function returns its factorial */
int fact(int n) {
int lcv; /* loop control variable */
int p; /* set to the product of the first lcv positive integers */
for(p=1, lcv=2; lcv <= n; p=p*lcv, lcv++);
return p;
}
