Unit 3 - Structure Chart
Structure chart is also known as input-process-output or hierarchy chart shows the overall program structure. It refers to planning diagrams similar to a
company’s organization chart. Structure chart depicts the organization of program but omit the specific processing logic. They describe what each part, or module, of the program does and they show how the modules relate to each other. Each module may be subdivided into succession of sub-modules that branch out under it. The charts are read from top to bottom and left to right. Figures 3.3 shows an example of a structure chart. This price of discount item problem was solved by a series of instructions to read data, perform calculations, and display results. Each steps was in sequence; that is we moved from one line to the next without skipping over any lines.
The main benefit of structure charts is in the initial planning program. We break down the major parts of a program so we can see what must be done in general. From this point, we can then refine each module into more detailed plans using flowcharts.
