Hi,

How can wrap some code with a method?

for example I have this code:

C++

if(x=y)
{
  agent.gotox();
}

and I want to put this in a method. It's not in main and its in other .cpp file.

Thanks

Please kindly consider to stop asking any questions here at CodeProject until you learn the very basics of programming using some elementary book and do most simple exercises on all topic of, say, C++. It should give you enough confidence; and you also will be able to collect some more sensible questions.

When you get this experience, welcome back. This would only make all kind of help from CodeProject members much more effective. Right now, it's too much of time loss.

Thank you for your understanding.

ok,thanks for your advice,but to become a c++ programmer with good experience i need to ask my questions,if you are sad of my questions please dont see the questions that the writer is me,thnanks

Thank you for your advice, but I think I already know what to see or pay attention for. The purpose of my comment is really to help you; and I disagree with you. You do not have to ask your questions, especially here, because it won't be effective. You need to read some book and learn what you can learn yourself first. With this initial background, your questions will be appreciated and the answers will really help you. Right now, this is not the case. I'm only trying to point out more effective way and save your time and time of others.

Yep, definitely more practical, 5++!

Than you very much.

C++

public void SendToX(Agent agent, int x, int y)
{
    if (x == y)
    {
        agent.gotox();
    }
}

That's C# code, John.

He's a programmer - he should be able to adjust. Right?

Sergey Alexandrovich Kryukov 22-Apr-11 21:16pm

No, he is not a programmer; isn't that obvious? (Not that it's your fault :-)

Do it in this way:

void my_function(int y,int& x)
{
  if(x=y)
  {
    agent.gotox();
  }
}

but remember:
if(x=y) is like x=y; if(0!=x) //...

x and y and agent are some variables that defined before this method,now how should it define?thanks

Why do you downgrade answers? Refine your question to get better answers. Nobody can understand what you want from that fuzzy code snippet. You have to tell more from your code or what you want to do.
Regards.

All correct, my 5, but... I think OP is simply not ready yet.
Please see my answer -- I think it makes some more sense, practically...

Solution 3

Method of what class? And how is the agent object related to such class?
If the agent is a data member of the class then you may use something similar to:

C++

//MyClass header file
class MyClass
{
//...
Agent agent;
public:
  void checkAndGo(int x, int y);
//...

C++

// MyClass source file
void MyClass::checkAndGo(int x, int y)
{
  if (x==y)
    agent.goto(x);
}

on the other hand, if agent isn't member of the class then you've to change the method's signature, for instance:

C++

void checkAndGo(int x, int y, Agent & agent);

He told you, read carefully

All correct (up-voted with my 5, hope it would compensate the bad vote...), but... I think OP is simply not ready yet.
