Programa para encontrar el siglo para un año.

Dado un año, la tarea es encontrar el siglo en el año dado. El primer siglo comienza del 1 al 100 y el segundo siglo comienza del 101 al 200 y así sucesivamente.

Ejemplos:  

Input : year = 1970
Output : 20 century 

Input : year = 1800
Output : 18 century  

// C++ code for find the century
// in a given year
#include <bits/stdc++.h>
using namespace std;
 
void find_century(int year)
{
    // No negative value is allow for year
    if (year <= 0)
        cout << "0 and negative is not allow"
             << "for a year";
 
    // If year is between 1 to 100 it
    // will come in 1st century
    else if (year <= 100)
        cout << "1st century\n";
 
    else if (year % 100 == 0)
        cout << year/ 100 <<" century";
    else
        cout << year/ 100 + 1 << " century";       
}
 
// Driven code
int main()
{
    int year = 2001;
    find_century(year);
    return 0;
}

// Java code for find the century
// in a given year
class GFG {
static void find_century(int year) {
 
    // No negative value is allow for year
    if (year <= 0)
    System.out.print("0 and negative is not allow"
                    + "for a year");
 
    // If year is between 1 to 100 it
    // will come in 1st century
    else if (year <= 100)
        System.out.print("1st century\n");
 
    else if (year % 100 == 0)
        System.out.print(year / 100 + " century");
 
    else
        System.out.print(year / 100 + 1 + " century");
}

public static void main(String[] args) {
    int year = 2001;
    find_century(year);
