Functions and Arguments

[newyorkcity]

hi everyone,

i am having trouble figuring out how to modify this function in such a way that it will return a default prompt (such as "enter string:") if called without an argument.

static string promptForString(string prompt)
{
	string ret_val;
	
	cout << prompt;
	getline(cin, ret_val);
	
	return ret_val;
}

my understanding is that the parameters must be supplied if declared within the prototype... however, my compiler (xcode) is throwing error messages if I have not supplied necessary params (i.e., calling 'promptForString();' will generate an error). can someone please enlighten me on how to do this? I would appreciate any help you can provide.

static string promptForString(string prompt = "enter it: ");

...

static string promptForString(string prompt)
{
	...
}

Hope this helps.

You need default arguments:

static string promptForString(string prompt="Enter String: ")
{
	string ret_val;
	
	cout << prompt;
	getline(cin, ret_val);
	
	return ret_val;
}

Great! That is exactly what I was looking for. Thanks Duoas and darkestfright!
