A programmer should adopt standard methodologies and approaches to program development. Software or program development life cycle is one such standard methodology that is applicable to all types of program development scenarios. It comprises of a number of interlinked phases with each phase serving a definite purpose.
Program creating and running comprises of four topics :
Program creating and running comprises of four topics :
- Structured Programming
- System Development Tools
- Developing a program
- Running a Program
1. Structured Programming :
Another important program developing approach is structured programming, which is subset of one of the key programming paradigms, i.e., procedural programming. It helps in making a program easily understandable and debug easily. A program that is not based on the structured programming approach is very difficult to maintain, debug, and understand.
Structured programming approach mainly focuses on the order of execution of the statements within a program. It suggests the use of sequential execution of statements in a program. Thus, structured programming approach suggests the use of mainly three types of control structure
- Sequential
- repetitive and
- Selective.
Further, it suggests avoiding the use of goto, break, and continue statements in a program as all these are unconditional branch statements.
System Development Tools will be explained in next post
