**You have been given A and B in range. Find the product of all numbers in the range. 1<=A<=100,000 and A<=B<=100,000**

#include<stdio.h>

int main(){

int a,b,prod=1;

scanf("%d %d",&a,&b);

if(a>=1 && a<=100000){

if(a<=b&&b<=100000){

for(int i=a;i<=b;i++) prod *= i;

}

}

printf("%d",prod);

}

i guess u cannot take calculate product of that much large numbers.
