Every time it is called, the parameters can be variable, so that the position of the line could be changed. The new program is as follows: Program Lesson. Thus we introduce the use of parameters in our procedure so that we can change the position of the characters within the procedure accordingly. An effort should always be made to eliminate the duplication of code. Using Procedures with Parameters Returning back to program Lesson. The whole Software Developement Lifecycle is a critical software engineering process which is divided into different stages facilitating the development of highly complicated software. Coding (or writing up your program) is just one section of the whole software developement process. Do slice your program into smaller chunks, and this needs the planning and design of the whole problem in hand prior starting to code. It would be much more difficult to find a mistake in a program if it would be one whole piece of code. They also enlarge the size of a program! You may run the program and notice a mistake at a certain point and which is located in a particular procedure/function. So procedures are an essential way to avoid repitions in a program. Repetitions in a program can cause a hard time for a programmer. I think that the first program is cumbersome, whilst the other is not! What do you think?!

To have an exact definition of a procedure, you should compare a program which includes a repeated section with another program avoiding the repeated sections by using a procedure, which is called several times. It can also have its own variables, which cannot be used with the main- program. They help the programmer to avoid repetitions.Ī procedure start off with a begin and ends up with an end. ![]() In a nutshell, this lesson will cover: Procedures.
