Program to find century for a year in C++

In this tutorial, we will be discussing a program to find the century for a year.

For this we will be provided with a year. Our task is to find the century in which the given year falls.

Example

#include <bits/stdc++.h>
using namespace std;
void find_century(int year){
   //year values can only be positive
   if (year <= 0)
      cout << "0 and negative is not allow"
         << "for a year";
   else if (year <= 100)
      cout << "1st century\n";
   else if (year % 100 == 0)
      cout << year/ 100 <<" century";
   else
      cout << year/ 100 + 1 << " century";
}
int main(){
   int year = 2001;
   find_century(year);
   return 0;
}

Output
