- 3. 3 Modular Programming Modular programming allows the program designer to simplify problems within the program by breaking down or dividing the problem into smaller sub- problems in order to be easily solved
- 5. 5 Benefit of Modular Programming 1) Reduces development time 2) Improves reliability 3) Increases standardization of the software development process 4) Simplifies modifications
- 6. 6 Variable Variable is a name that represents a data element. Variable is also a temporary storage place for data in memory whose contents can change Variables consist of two types, namely local and global variable
- 7. 7 Local Variable Local variable is a variable declared in a function or procedure. This variable can only be recognized within the function or procedure itself. Local variables cannot be called, accessed and changed by other procedures or functions, even by the main program
- 8. 8 Global Variable Global variable is a variable that is defined in the main program and can be used in the main program or other sub-programs. The value of this variable can be called, accessed and changed by any procedure or function contained in the program
- 9. 9 What is Function? Function is a subprogram that receives input data, performs several processes, returns output values for use by the process that calls the function The function is also often called non-void functions. Called non-void because it returns value that comes from the output of the function
- 10. 10 Characteristics of Function 1) Have data type that starts the function 2) Don't have void keyword 3) Has a keyword return 4) Has a return value
- 12. What is Procedure? Procedure is a series of instructions named, and performs a specific purpose. As with functions, procedures work with a call- return mechanism The procedure is also often referred to as void function. Called void because the function does not return an output value obtained from the results of the function's process 12
- 13. Characteristics of Procedure 1) Does not have keyword return 2) Does not have a data type in the function declaration 3) Use the void keyword 4) Cannot immediately display the results 5) Has no function return value 13
- 15. What is Unit? Unit is a library that is generally in the form of procedures or functions The difference between unit and preprocessor directive is that the unit is a library developed by user while directive preprocessor is a standard library that has been provided by C 15
