Functions in C++

Declaring and Using Functions

 A function is a block of code that performs a specific task.

 Functions help break down a large program into small manageable tasks.

 A function can be called multiple times from different parts of a program.

 To declare a function, use the following syntax:

 return_type name(parameters) {

 // function body

 }

 The return_type specifies the type of value the function will return.

 The name is the identifier for the function.

 The parameters are optional and specify the input values for the function.

Example

int add(int a, int b) {

return a + b;

}

 To call the function, use the following syntax:

 int result = add(2, 3);

Best Practices

 Use descriptive names for functions.

 Include comments to explain the purpose of the function.

 Handle errors and exceptions within the function.

 Follow a consistent coding standard.
