header files

[soniw23]

Im new to programming and i want to know can you make your own header files in C or C++?

[redhead]

yes, a description is to be found here a closer use of it in contence, is to be found here.

[fp_unit]

/* Filename: Simple.h */
/* These 2 lines below, and the final one at the bottom are recommended.
 * You should include them in all your header files so functions/data types
 * don't get defined (#included) twice.
 */
#ifndef YOUR_HEADER_NAME_DEFINED
#define YOUR_HEADER_NAME_DEFINED

/* put #defines, #includeds, const values, classes, 
 * typedefs and prototypes here */

#include <iostream>
#include <cstring>
using std::cout;
using std::strcpy;

class Simple
{
private:
   char * str_;

public:

    Simple(const char* str) { strcpy(str_, str); }
    char* getString() { return str_; }
    void print() const { cout << str_ << '\n'; }
};

#endif

/* Filename: main.cpp */
#include "Simple.h"

int main()
{
    Simple string1("I am a string!");
    string1.print();

    return 0;
}

If you're using Linux, make sure the two files are in the same directory and use g++ to compile:

[shell]$ g++ -o Simple main.cpp
[shell]$ ./Simple
I am a string!
[shell]$
