4-4 Advantages of structured programming 1. Structured programs are easier to write because the programmer can study the overall problem first and then deal with the details later. 2. Modules (functions) written for one application can be used for other applications (this is called reusable code). 3. Structured programs are easier to debug because each module is designed to perform just one task and thus it can be tested separately from the other modules. 4. Structured programming is effective in a teamwork environment because several people can work on a common program, each person developing one or more modules. 5. Structured programs are easier to understand and modify, especially if meaningful names are chosen for the modules and if the documentation clearly identifies the module’s task. Z.R.K
4-5 Steps for developing a computer solution Table 4.1–1 1. State the problem concisely. 2. Specify the data to be used by the program. This is the “input.” 3. Specify the information to be generated by the program. This is the “output.” 4. Work through the solution steps by hand or with a calculator; use a simpler set of data if necessary. 5. Write and run the program. 6. Check the output of the program with your hand solution. 7. Run the program with your input data and perform a reality check on the output. 8. If you will use the program as a general tool in the future, test it by running it for a range of reasonable data values; perform a reality check on the results. Z.R.K
