Check if a large number is divisible by 25 or not in C++
Here we will see how to check a number is divisible by 25 or not. In this case the number is very large number. So we put the number as string.
A number will be divisible by 25, when the last two digits are 00, or they are divisible by 25.
Example
#include <bits/stdc++.h>
using namespace std;
bool isDiv25(string num){
int n = num.length();
int last_two_digit_val = (num[n-2] - '0') * 10 + ((num[n-1] - '0'));
if(last_two_digit_val % 25 == 0)
return true;
return false;
}
int main() {
string num = "451851549333150";
if(isDiv25(num)){
cout << "Divisible";
} else {
cout << "Not Divisible";
}
}Output
Divisible
