Config Defaults

A small settings struct keeps related project defaults together.

config_defaults.cpp

#include <iostream>

struct Settings {
    int retries;
    int timeout;
};

int main() {
    int requestedTimeout = ;

    Settings settings{3, requestedTimeout};
    int totalWait = settings.retries * settings.timeout;

    std::cout << "retries=" << settings.retries << std::endl;
    std::cout << "timeout=" << settings.timeout << std::endl;
    std::cout << "totalWait=" << totalWait << std::endl;
    return 0;
}

settings Grouping configuration values in a struct makes the data easy to pass and inspect.

defaults Defaults should be explicit so later calculations can use one named source of truth.
