Document Summary

The act of finding a solution to a perplexing, distressing, vexing, or unsettled question. Similar problems come up again and again. A good programmer recognizes a task/subtask that has been solved before and plugs in solution. Break up a large problem into smaller units and solve each smaller problem. Approach can be applied over and over until each subtask is manageable. Restate problem as a list of tasks (modules) Restate each abstract module as a list of tasks. Process ends when all steps (modules) are concrete. A set of unambiguous instructions for solving a problem or subproblem in a finite amount of time using a finite amount of data. E. x: write enter temperature , read temperature, determine what to wear. Top-down design- focuses on tasks to be done. Object-oriented design- focuses on that data involved in the solution. Control structure- an instruction that determines the order of execution of instructions in a program.
