Question

i have a function that read config file and i wanted to reload this function to get the new variables

void readConfigFile()
{
    ifstream File;
    File.open("config.txt", ios::in);
    while (!File.eof()){
        string line;
        int Hour;
        int Minuts;
        getline(File, line);
        File >> Hour >> Minuts;
    }
    File.close();
}

int main()
{
    readConfigFile();
    while (1) {
        time_t now;
        struct tm *current;
        now = time(0);
        current = localtime(&now);
        if( current->tm_hour == Hour && current->tm_min == Minuts){
            std::cout <<  "Done" << std::endl;
        }
        Sleep(5000);
    }

    return 0;
}

how i can reload this readConfigFile() function to get the new Hour / Minuts while application running

for example

if(Clicked Button){

reload readConfigFile();

}

while i searching on internet about reload

i found that i can do that with operators overloading

but i couldnt use it

i am still begainner 🙁

Thank You 🙂

I’m guessing that the problem is that the variables Hour and Minuts (sic) are local to the readConfigFile function.

That means that whenever you call readConfigFile you only change those local variables, not whatever global variabled you might have.

If those variables were global, then you just have to call readConfigFile again, and it will read into them again.
