Study Notes
Functions in Computer Science
- Modularization is the process of breaking large programs into smaller subprograms called functions.
- Merits of modular programming include reducing program size, decreasing chances of errors, reducing complexity, and improving reusability.
- Functions are named units of statements in a program that perform specific tasks.
- C++ provides predefined functions for various tasks, some of which require parameters or arguments.
- Parameters or arguments are provided within the parentheses of the function name.
- Some functions return a value after performing a task, while others only perform the specified task without returning a value.
- Mathematical functions can be accessed using the "math.h" library.
- String functions can be accessed using the "string.h" library.
- There are also other types of functions available, which are not specified in the given text.
- Functions help in organizing and structuring code, making it easier to understand and maintain.
- Using functions can improve code reusability and save time in programming.
- Functions play a crucial role in the modular design and development of software programs.
