Programming

Question 14

What are the five-step process of programming?

Answer 14

1. Define the problem
2. Design the solution/program
3. Code the program
4. Test the program
5. Document the program

Question 15

It means that there should be clear understanding of the problem

Answer 15

Problem Definition Step

Question 16

the Problem Definitiion Step requires performing the following:

Answer 16

1. Specify program objectives and identify the users of the program.
2. Specify the output requirements.
3. Specify the input requirements.
4. Specify processing requirements.
5. Study feasibility of implementing the program.
6. Document the analysis.

Question 17

In designing the program, the following steps are done:

Answer 17

1. Determine the program logic through top-down approach and modularization, using
   hierarchy charts.
2. Design details using pseudo-code and /or flowcharts.
3. Test design with a structural walkthrough. Structural walkthrough consists of
   reviewing process with other programmers and system analyst and scrutinize
   (“walkthrough”) the programmer’s work.

Question 18

Is the step which translates the logic of the program based on the pseudo-code
(algorithm) or flowcharts into a high-level programming language using the syntax and
semantics of the specific language.

Answer 18

Program Coding

Question 19

It consists of desk checking, debugging, and running real data to make sure that
the program works.

Answer 19

Program Testing

Question 20

Is just reading through or checking the program manually to

ensure that it is free from errors and the logic works.

Answer 20

Desk Checking

Question 21

It means detecting, locating, and

removing errors in the computer program.

Answer 21

Debugging

Question 22

An Error that can be a typographical error or incorrect format of the statement used.

Answer 22

Syntax Error

Question 23

Errors that are

caused by incorrect use of control structures.

Answer 23

Logic Error

Question 24

It consists of the written descriptions of what the program is all about
and how to use it.

Answer 24

Documenting a program
