Do you know why??? #include #include void main() { int n, count, factorial; clrscr(); printf("Enter a positive integer: "); scanf("%i", &n); printf("Integer \t Factorial\n"); for (n = 1; n >= 1; --n) { printf(" %3i ", n); factorial = 1; for (count = 1; count <= n; ++count) factorial *= count; printf("%i\n", factorial); } getch(); } Thanks Xiang
