C++ 5/12/2011 Programing with the problem Analysis-Coding-Execution Cycle Programing is a process of problem solving. Algorithm: A step by step problem solving process in which a solution is arrived at in a finite amount of time. Steps in programing to solve a problem: Step 1: Analyze the problem Outline the problem and its requirements Design steps (algorithm) to solve the problem Step 2: Implement the algorithm Implement the algorithm in code Verify that the algorithm works Step 3: Maintenance Use and modify the program if the problem domain changes

Unformatted text preview: The first step requires : • Thoroughly understand the problem • Understand problem requirements – Does program require user interaction? – Does program manipulate data? – What is the output? • If the problem is complex, divide it into subproblems – Analyze each subproblem as above • If problem was broken into subproblems – Design algorithms for each subproblem • Check the correctness of algorithm – Can test using sample data – Some mathematical analysis might be required...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
