What is a function?

Question

function is very complicated can anyone tell me an easy way for learning functions?

Answer 1

A function is a group of statements that together perform a task. Every C++ program has at least one function, which is main(), and all the most trivial programs can define additional functions.
A function declaration tells the compiler about a function's name, return type, and parameters. A function definition provides the actual body of the function. A C++ function definition consists of a function header and a function body.

Answer 2

A function is a set of orders that are ready to do something!
when you need to do the same task in many programs, you can write a function and save it
then you can access it and give him related arguments and get the results
thus you have saved your self some time and didn't write the same set of orders over and over again
for example plus action is predefined in a function by the platform that sums arguments
you can create a function that can uses plus sign to multiply argumants

Answer 3

Function is nothing but the action taken on different attributes. Set of statements are used in function to perform particular task.
eg. If I want to add two integers then I'll just call the add() function and pass it 2 integers it'll return me the addition..

Answer 4

functions are mathematical objects that return a value upon input. You can think in something similar in the case of programming. You define your function passing arguments and returning values or nothing (void).

Answer 5

A function is a set of statements used to resolve a problem located out the main program, it's used to avoid repetition of code it's written once and called many times, and for program modulation that means divide the program into subprograms a program that use functions is more visible, understandable, robust and efficient than a program that write everything in a single program

Answer 7

For solving any programming problem,we devided large programme into number of entities ,these entities known as functions.
I hope ! I define the function in very easy way.

Answer 8

a function is group of code which can act as we want
