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.
