Can someone help me on functions in c++

[pears]

You'll need to be a bit more specific than that

[Rajnish Kaushik]

i did not understood anything on functions

[pears]

What exactly are you having trouble with? Do you have an example?

[Rajnish Kaushik]

How to i use it in programs and why?

A function is a piece of code with a name. You can provide it with values and it can return a value when it completes. It is a type of subroutine.

What are you asking, I know java, so it might not be the same for c++, but a function could be 8+4, if maybe you are trying to make a math application, or are you asking about something defining a function?

simple school level functions in c++

I'm going to have to do some research in it.

A function is a way to encapsulate a block of code. Say you have to do some computation multiple times. Instead of repeating the code that does the computation multiple times, you enclose that code in a function, and call the function every time you need to do the computation. A big advantage of this is that if you need to modify the computation code, you only need to do that in one place.

Another important use for functions is to decompose other long functions. Say you have a function where you first do A, then B, and then C. It is a good idea to separate the code that does A into a function, the code that does B into another function, and the code that does C into yet another function. Then you have your function just call those three functions. This makes it much easier to read and maintain you code.

If you find it difficult to use a function in a C ++ language that you can describe ???

Functions return a value but it can be an array... 

Recursive functions can call the same function again eg. Fibonacci
