Plzz refer my c++ code for better understanding of the logic

#include <iostream>
using namespace std;


void maxi(){
    int a, b, c;
    cin >> a >> b >> c;
    int max_value = a;
    if (b > max_value) {
        max_value = b;
    }
    if (c > max_value) {
        max_value = c;
    }
    cout<< max_value <<endl;
}

int main() {
    int N;
    cin>>N;
    while(N--)
    {
        maxi();
    }
}
