A simple piece of modular arithmetic will give you the answer. The only possible trick is reading the months correctly (there are 13 of them and they are not all standard).

An example solution in C++14 is given below

#include <bits/stdc++.h>
using namespace std;

int main(){
    string months[13] = {"January", "February",
                         "March", "April",
                         "May", "June",
                         "July", "August",
                         "September", "Spooktober",
                         "November", "December",
    string month;
    int k, next_month;
    cin >> month >> k;
    for(int i = 0; i < 13; ++i){
        if(month == months[i]){
            next_month = (i+k)%13;
    cout << months[next_month];
    return 0;
