Thread: Returning a value from a function

err... what value are you returning, and why do you declare the return value as void if you want to return something?

Code:

void processL()
{
	.....
	.....
	if(nameLine==Name && passLine==Password)
	{
		valid = false;
		return valid
	}
// and what value are you returning if you get here?
}

A void function cannot return a value...it has to be an int function or float etc. Do you not also need to pass parameters?

Edited out: Why, if you are using the value returned from processA in processL is there no value returned in A?

Code:

int processL(int valid)
{
	int completeandutterloser = -1;
        .....
	.....
	if(nameLine==Name && passLine==Password)
	{
		valid = false;
		return valid
	}
        return completeandutterloser; 
}

Code:

void processA(int valid)
{
	.....
	.....
	check = customerLogin();
        if(check == true)
	  {
	      cout<<"success";
	  }
	else
	   cout<<"Failed";
          
}

I could be wrong as that might not do what you want it to (feedback if I am right please) If valid is not a parameter of processL then you have to define it in processL.....I think!

Woops

Apart from that was I right?


Edit: I had a dumb and dumberndumberer moment there for some reason I was thinking false was a variable and valid was now equal to that!

/me shoots homself in the foot!
