/*Exercise 4 Write a function called factorialN that will take an integer number n as input, and calculate 1*2*3…*n and print the result on the screen. Hint: the function header will be void factorialN (int n)*/ #include <stdio.h> #include <stdlib.h> void factorialN(int number); int main() { int number; int product=1; printf("please enter a number: "); scanf("%d",&number); int i; for(int i=1;i<=number;i++) { product=product*i; } printf("the product between 1 and %d is = %d",number,product); return 0; }
