Is it possible to use output from void function in an if statment in another function

void RightsCheck()
{
    // Check if I have admin rights && save it to fReturn
    // cout << fReturn;
}

void RunApp()
{
    if (fReturn == 1)
    {
        printf("Admin");
    }
    
    else if (fReturn == 0)
    {
        printf("User");
    }
}

  • A void function by definition doesn't return a value in c++. You can pass a parameter by reference and check its value after calling the function.

  • Or make the function return a value. [Demo](https://godbolt.org/z/nfoxGE7PG) – rturrado Nov 15 '22 at 08:44
