Study Notes
Modular Programming
- Modular programming involves breaking a program into smaller, manageable functions or modules to improve maintainability and simplify the process of writing programs.
Functions
- A function is a collection of statements that perform a specific task.
- Functions can be called multiple times from different parts of a program.
Defining and Calling Functions
- A function call is a statement that causes a function to execute.
- A function definition consists of statements that make up a function.
Function Definition
- A function definition includes:
- Return type: the data type of the value returned to the part of the program that called the function.
- Name: the name of the function, following the same rules as variables.
- Parameter list: variables containing values passed to the function.
- Body: statements that perform the function's task, enclosed in {}.
Note
- The function header is the line that starts with the return type, such as
int main().
