Quickest solution to the problem of a class function holding a global variable's name

As the title states...

Code:

---

int MyVariable;

class MyClass
{
  public:
      int MyVariable;
      void MyFunction(int MyVariable);
};

void MyClass::MyFunction(int MyVariable)
{
  MyVariable = 3; //Access the argument variable
  ::MyVariable = 12; //Access the global variable
  this->MyVariable = 567; //Access the local variable
}

Not what i mean

Its a funtion not a variable that holds the same name as a
global variable and the compiler doesnt aprove it

Quote:

Error: param.cpp(7,2):Multiple declaration for 'Var'

You can't have two identifiers with the same name, wether they be variables or functions. Use another name (like put an i in front of the variable if it's an integer).

You can do this (i think this is what you mean)

Code:

---


int some_number(void) {
    return 10;
}

class myClass {
protected:
    int some_number;
public:
    void set(int);
};

void myClass :: set(int some_number) {
    this->some_number = some_number;
}

---

I think you are doing this:

Code:

---

int free;

void free(void *) {
    ....
}

---

And that is illegal. However, you can always use namespaces to do this.

Code:

---

namespace first {
  int free;
}

namespace second {
  void free(void *) { }
}

int main(void) {
    using namespace first;
    free = 10;
    void *someptr;

    for(int i = 0; i < free; i++) {
        using namespace second;
        free(someptr);
    }
}
