| | Re: Project Which IDE are you using ? The process normally involves creating a new console project (if thats what you want), adding the required header and source files to it (preferably in the same folder). The header and the source files are generally added by right clicking on the project name … |

| | You need to tell the compiler that the class you are using exists. You do this by something known as forward declarations. [code=cplusplus] // Enemy.h #ifndef ENEMY_H #define ENEMY_H class Player ; // forward declaration class Enemy { int c ; int d ; public: int get (Player a) ; … |
| | [quote=joeprogrammer;324849]But the OP did this. Reread the code; there's nothing wrong with the way he/she implemented preprocessor directives.[/quote] ....albeit, in a wrong way. When you write guards like that to prevent recursive inclusion, you need to specify the Header file name in the preprocessor directives and not the class name. … |
| | The first sequence you posted has a distinct pattern, but I see no repeating or logical pattern in the second sequence ? Try to put down your thoughts in a more concise manner and you would yourself know the algorithm. |

| | Re: Class Error The way you are trying to incorporate the wrong concept of const variables in your program is causing all the problems. If you declare a variable as const, you need to specify the const qualifier before the dataype, like this: [code=c] const int SIZE = 10 ; // you must … |

 | As far as virtual functions are concerned, they definately incur some performance overhead, but in normal senarios, the cost and nightmares of maintaining repeatitive code is far more than that when virtual functions are used. The most important point you have to consider while using virtuals is that the [U]binding … |

[code=c] … |
| | Re: C++ on linux That is becuase the functions which you mentioned are compiler specific (Turbo C specific) and not part of the standard library. They can be easily removed and circumvented or replaced. For a list of all standard functions in C and C++ see [URL="http://www.cppreference.com"]this[/URL]... As an example, you can remove getche() …  |

| | Two problems I can see: • Your memory allocation is not proper. Each of your rows share a common vector variable because of the stmt: [code=cplusplus] vector<int> v(n); vector<vector<int> > data(n,v); [/code] Here the memory for each inner row is getting allocated only once and your two dimensional matrix gets … |

 | Some points: • You are missing two closing braces at the end of the program. • In your class definition remove the class names before the functions since they are only needed when you provide function body to your functions outside the class. [CODE=cplusplus]GridActive& GridActive::operator= (const GridActive & grid); // … |
 | [quote=iamthwee;319062]You just don't use malloc with c++ period. Unless you want undefined behaviour.[/quote]That would be only if you use them to allocate memory for non-POD (plain old data). For datatypes like integers, floats etc. you can still use malloc though is much frowned upon in the C++ community. |
