What is PDLC program development life cycle mean?

Answer 1

PDLC stands for the program development life cycle. It consists of various steps to develop a program for solving a particular problem. the following steps are used for development:

1. problem analysis

2. design of the program

3. algorithm and flow chart

4. coding of the program

5. debugging and testing

6. documentation

7. maintenance of program

1. Problem analysis includes the information attainment using interviews, questionnaires, discussion and reports so that designer can understand that what is the problem and what will required to solve it.

2. design of the program after problem analysis designer have the clear view of what a problem is? Now he have to decide about the input requirements, variables as well as control structures by keeping in mind the output required.

3. Algorithm and flowchart after design phase we have to made an algorithm. basically algorithm is the finite set of instructions written in sequential order to solve the problem. Then after flow chart is made on the basis of the algorithm whereas flowchart is the logical design of algorithm.

4. Coding phase It is the crucial job of programmer to develop a code by following the flowchart and that code is written in any computer language. The main point to keep in mind is that it should be effective enough to got the output and the number of statements should be less.

5. Debugging and Testing This phase includes the testing of the code developed by programmer. So that code can be made error free.

6. Documentation This task is performed by the programmer to made the code user friendly i.e. if new person got the code then he/she can easily understand that which statement performed what task...

7. Maintenance now the program is developed but it is required to made the code error free till the red signal is not get by the user.
