Returning a value from a function

hi there, i tried to return a value from a function and the value returned will be used another function. here is my code

Code:

---


void processL()
{
        .....
        .....
        if(nameLine==Name && passLine==Password)
        {
                valid = false;
                return valid
        }
}

---

Code:

---

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

---

i meant to use the value returned on processA(), but i'm unable to do it. can u give some help or advice ??

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!

You would want to return a bool, not int, since the code uses true and false. And there is no need for a parameter here.

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!
