can any one give here example for how to access function written in another file...??

Answer 1

Assuming you are using classes in a header file to write the functions, here is a simple example.

Let's say you have a function called help within a class in a header file. In the main Cpp file, you want to #include "headerfile.h" (headerfile is the name of your file)
If your class name is something like myClass, then in the cpp file, you will use dot notation to access those functions in the other file.

First, declare a variable for it
myClass ex;

Now, you can call your help function using this variable like so:
ex.help();
The function is now called from the other file.

If you have arguments in that help function calling an integer:
ex.help(15);

I hope this helps!
