Благодаря, за пореден път, за помощта. Мисля, че си оправих грешките и според мен програмата работи коректно, но judge не ми дава точки. Не мога да разбера защо.

#include<iostream>
#include<string>
using namespace std;
void showSuccessMassage(string operations, string massage);
void showWarningMassage(string massage);
void showErrorMassage(string operations, string massage, string errorCode);
void readAndProcessMassage(string massageType);
int main(){
int N;
cin >> N;
for (int i = 0; i <= N; i++){
    string massageType;
    getline(cin, massageType);
    readAndProcessMassage(massageType);
}
return 0;
}
void showSuccessMassage(string operations, string massage){
    cout << "Successfully executed " << operations << "." << endl;
    string line = "Successfully executed " + operations + ".";
    int length = line.size();
    cout << string(length, '=') << endl;
    cout << massage << "." << endl;
}

    cout << "Warning: " << massage << "." << endl;
    string line = "Warning: " + massage + ".";
    int length = line.size();
