[Solved] Passing value from one function to another [closed]

by


You can pass objects to functions as arguments. Here, fnMainMenu takes a reference to a constant std::string object as parameter and prints it out to stdout:

void fnMainMenu(const std::string& msg)
{
  std::cout << msg << "\n";
}

Then fnLogin() can call the function and pass it any string it likes:

void fnLogin()
{
  std::string s = "hello";
  fnMainMenu(s); // call Main Menu and I want to pass "hello"

}
