INTRODUCTION  Program development life cycle (PDLC) is an outline of each of the steps used to build software applications.  tool used to guide computer programmers through the development of an application.  Division of software development work into distinct phase(stage)  PDLC refers to the changes made from an old to a new program (recycle)

7 STEPS OF PROGRAMMING LIFE CYCLE

STEP 1:SPECIFY THE PROBLEM  Define the problem to be solved  Write the program specification: descriptions of the program input,output and user interface (UI) STEP 2:DESIGN THE PROGRAM  Develop a detailed logic plan using pseudocode,flowcharts,object structure diagrams

STEP 3: CODE THE PROGRAM  Translate the design into an application using a programming language or application development tool by creating the user interface and writing code include internal documentation comments and remarks within the code that explain the purpose of code statements. STEP 4: TEST AND DEBUG THE PROGRAM  Test the program, finding and correcting errors (debugging) until it is error free and contains enough safeguards to ensure the desired results.

STEP 5: RUN/EXCUTE (FORMALIZE THE SOLUTION)  To run the program on a computer. When you run a C++ program, first the program will compile the program. This translates the human code into binary language. When you run the program, you will do further testing.  There are two main types of errors, syntax and logic errors. Syntax errors are problems with grammar, spelling, or punctuation. If you have left of a semi colon or added one where you shouldn’t have or misspelled a reserve word, these are all syntax errors. These are the easiest one to find because the program itself helps you to find them.

STEP 6: DOCUMENT  To Document is to put together all of the materials that have been generated throughout the PDLC process. All of the flowcharts, messages, algorithms, lines of code, and the user manuals are part of this documentation. Internal documentation is used by other programmers to help them know why you did something a certain way or tell them how you wrote a program.

STEP 7: MAINTAIN THE PROGRAM  To maintain is to make sure that the program keeps running as it should and to do any needed updating or fixing. Maintenance is the longest phase of the PFLC.
