it does nothing

[barren hedge]

i wrote this code but it does nothing,why?and how can i fix it?
#include <iostream>
#include <fstream>
using namespace std;

int main() {
ifstream input("maximpar.in");
ofstream output("maximpar.out");

if (!input.is_open() || !output.is_open()) {
    cout << "Eroare la deschiderea fisierelor de intrare/iesire." << endl;
    return 1; // Returneaza cod de eroare
}

int n, numar, maxPar = -1, ap = 0;

input >> n;

for (int i = 1; i <= n; ++i) {
    input >> numar;

    if (numar % 2 == 0) {
        if (numar > maxPar) {
            maxPar = numar;
            ap = 1;
        } else if (numar == maxPar) {
            ap++;
        }
    }
}

if (maxPar != -1) {
    output << maxPar << " " << ap << endl;
} else {
    output << -1 << endl;
}

input.close();
output.close();

return 0;

}

what does "nothing" mean here

honestly step trough it with a debugger to see whats up

I run it,but it starts and stops.I saw that maximpar.in is never created,just maximpar.out.idk what to do

Did you try debugging it

[barren hedge]

ye,it says that it exited with error code 0,there isnt't any error,just that the program doesn't do anything,and it should

[upbeat lintel]

The code seems to be perfectly fine tho

Aren't you supposed to create the file yourself? it's the input

create the file, put in the numbers you want and it should work
