How to Create your own Header File in C/C++? The source file contains #include which is responsible for directing the C/C++ compiler that this file needs to be processed before compilation and includes all the necessary data type and function definitions. Instead of writing a large and complex code, you can create your own header files and include it in the C/C++ library to use it whenever you wish as frequently as you like. It enhances code functionality and readability. Let us understand how to create your own header file in C++ with the help of an example.Ĭonsider a problem where you want to compute the factorial of a number. Since it not pre-defined in the standard C++ library, you can create it by yourself! The Steps involved are- Step – 1 INSTALL CONIO LIBRARY UBUNTU HOW TO

Write your own code in C++ and save the file with a.

cpp, because you are creating a header file, not a C++ program. h extension would be the name of your header file. int factorial(int number)įor(iteration=1 iteration – Enclosing the header file name within angular brackets signifies that the header file is located in the standard folder of all other header files of C/C++. Step – 3Īfter the code is written using your file with the. h extension, compile and run your program. This is a C++ program to find the factorial of a number using a self-created header file: #include INSTALL CONIO LIBRARY UBUNTU CODE Used to perform input and output operations in C like scanf() and printf(). Perform string manipulation operations like strlen and strcpy. Restart or Close your IDE and open it again.

Just copy file and paste file conio.h on /usr/include/ but don't forget before you want copy paste on /usr/include/ you must open folder as ADMINISTRATOR first !! Step 1 :

getch - Get char entry from the console.

cprintf - Formats values and writes them directly to the console.

cputs - Writes a string directly to the console.

putch - Writes a character directly to the console.

cscanf - Reads formatted values directly from the console.

gcgets - Reads a string directly from the console.

kbhit - Determines if a keyboard key was pressed.

Some of it's functions which are often used :
