This best-selling publication is designed for readers who want to solve common business challenges through programming techniques. Readers are guided to properly define the problem, divide it into modules, design a solution algorithm, and prove the algorithms correctness, before commencing any program code. By using pseudocode and modern programming techniques, the programmer can concentrate on developing a well-designed and correct solution, and thus eliminate many frustrating hours at the testing phase. This comprehensive and practical text provides thorough coverage and practical examples relating to business applications, and features a consistently structured approach when representing algorithms in hierarchy charts. The text is divided into two sections, the first covering algorithm design in the context of traditional programming and languages, and the second addressing algorithm design in the context of object-oriented programming. Coverage of these two key contexts equips students with the knowledge to solve day-to-day common business programming errors.
