It is the most challenging aspect of programming to judge whether a program is wrong or why it is wrong. Here you build your preventative design by:
(1). Write the code clearly, you should indent it appropriately, using the literal description and descriptive variable name.
(2). Code should be simple, focus on complex expressions in simple statements, rather than some complex statements. Turbo C code optimization mechanism will greatly improve the efficiency of the Code, and debugging, reading, modified easily.
(3). Try to build the program with a function that is simple and well defined. This facilitates debugging and analysis, and is easier to read and modify.
(4). The data required by each function should be minimized and the number of elements changed. This also facilitates the preparation of test procedures and analysis results, as well as readability and modification of procedures. It also limits the potential for the huge clutter involved in an error function to run multiple functions several times in a debug section.
(5). Be mindful of writing common functions in programs, or functions that are reusable in other programs. Writing and debugging a generic function is usually easier than writing and debugging two or more special functions.
