Study Notes
Functions in C++ Programming
- A function is a block of code that can be called multiple times from different parts of a program, making it reusable.
- Benefits of using functions include:
- Constructing programs from simple, small components
- Avoiding repeated code
- Enabling software reuse by packaging functions into library codes
- A function involves two parties: the caller and the function being called
- The caller passes arguments to the function, which receives them, performs operations, and returns a result back to the caller
- Functions promote ease of maintenance and understanding by reducing code repetition
- A function prototype (declaration) is required before its implementation
Example: Using Functions
- Suppose we need to evaluate the square of two integers multiple times
- We can write a function called
getSquare()to perform this operation - The
getSquare()function can be reused whenever needed, avoiding code repetition - The function would take an integer as an argument, perform the square operation, and return the result
