    Making a new method

    Hello, programmers. I`ve made a code in C++, done some methods, but I cant get past this one. I need to make a method that shows the MaxRAM value for example the methods name would be GetMaxRAM.

    Bare in mind, GetAtm and SetAtm are methods for RAM therefore, Getting the RAM value and setting it.

    How could i make a method in ComputerNetwork class that gives me MAX Ram value at the end of the program?


    The code is here:

    Code:
    #include <iostream.h>#include <conio.h>
    #include <stdio.h>
    class OverflowException {
       public:
          OverflowException() {
                cout << endl << "Exception created!" << endl;
          }
          OverflowException(OverflowException&) {
             cout << "Exception copied!" << endl;
            }
          ~OverflowException() {
             cout << "Exception finished!" << endl;
          }
    };
    class Computer {
        protected:
            char* CPU;
            float freq;
            short RAM;
        public:
            Computer();
            Computer(char*, float, short);
            virtual ~Computer() {
                cout << "Message from the \"Computer\" - destroyed!" << endl;
            }
            char* GetProcesors() const {
                return CPU;
            }
            void SetProcesors(char* CPU) {
                this->CPU = CPU;
            }
            float GetFrekv() const;
            void SetFrekv(float);

    perhaps show your attempt on the function GetMaxRam() and describe what problem you are having with it, in light of the work you have posted so far.

    What does "MAX Ram value" mean?

    I don't understand what GetAtm or SetAtm are for either, i.e how they have any relation to what you are asking, and why they are of type 'short'.

    You're not getting a useful response quickly because you haven't explained the problem well enough.

    1. You're using void main(), this is wrong, you should be using int main().
    2. You're using deprecated headers, use <iostream> instead of <iostream.h>, and don't use <conio.h> at all, also, use <cstdio> instead of <stdio.h>.
    3. You're using char* instead of std::string, why?
    4. Don't use getch()
    5. Don't use raw array, use std::vector or some other form of STL container instead.
    6. I suggest using smart pointers instead of managing memory by hand.
    7. Are you by any chance a Java programmer? Stuff like this smells like Java to me:

    Code:
    inline void Computer::SetAtm(short RAM) {
        this->RAM = RAM;
    }
    Just use a different name for the parameter and lose the "this->". Imo atleast.

    8. I get the feeling you're using some ancient compiler from the 90's. Don't.
    9. Your indentation is inconsistent, it shouldn't be.
    10. Would it kill you to use some spacing? It's very crammed, which makes it harder to follow.

    Fix the above, and we will have a much easier time helping you.

    If he stole that, he needs to find a new place to take code from. It looks like C++ and C had a baby with a learning disorder, dropped it on its head at birth and made it live in a closet with nothing to eat but noodles and rat feces for 21 years, then released it into the world and said "Go crazy."

    Here's where OverflowException came from, as well as a lot of other structural stuff..

    Code:
         while (kbhit())
             getch();
          getch();
    This is ...unfortunate.
