Header files are also called library of C, C++, which include definition of C, C++ built in functions. To create a header file in C, C++, we are using TURBOC as editor. First we need to create a file including macro or function and save it with .h extension in include folder of TC, (eg: c:/tc/bin/head.h).
code : head.h
void fun()
{
cout<<“Best Programming Institute in delhi”;
}
and after that we can include header file in our program,
code : file.cpp
#include<iostream.h>
#include<head.h>
void main()
{
cout<<“we are learning how to make header file in c++ \n”;
fun();
}

thankyou sir ………………
What is Macro?????????
to define a macros in c, c++ we are using #define preprocessor. The advantage of a macro is that the it can replace repeated statement.
for example :
define SQR(x) x*x
now we can call SQR(x) macro anywhere in our program
It’s the best institute for me.
