Function in c++
- The functions play an important role in C program development. Dividing a program into functions is one of the major principles of top-down , structured programming.
- A large program can be split into smaller sub-programs (blocks) called as functions where each sub-program can perform some specific functionality.
- Function can reduce the size and complexity of a program, makes it easier to understand ,test, and check for errors.
- The functions which are available by default are known as "Built-in" functions and user can create their own functions known as "User-defined" functions.
- A function can accept parameters, which are pieces of data.
Creating A Function
Create a Function C++ offers a few predefined functions, like main(), which are used to run code. However, you can also develop your own functions to carry out particular tasks.
Syntax
void myFunction()
{
// code to be executed
}
{
// code to be executed
}
