Module Questions

  1. What are the steps in the Program Development Life Cycle?

  2. Create Psuedo-code for the following problem:

    Suppose you are asked to develop a program that converts dog years to human years. Assume that the computation for dog years is 7 times that of a human year. Your program should ask the user for their dog's name and their dog's age, followed by an output indication of the dogs name and how old it is in human years.

  1. What does the following code snippet output:

double gradeOne = 99.0; double gradeTwo = 97.00; double gradeThree = 95.0; double average = 0.0; string programHeader = "Welcome to my Grade Calculator!\n"; cout << programHeader; average = (gradeOne + gradeTwo + gradeThree) / 3; cout << "The Average is: " << average << endl;

 

 

  1. What does the following code snippet output and explain why there is a logical issue:

double gradeOne = 99.0; double gradeTwo = 97.00; double gradeThree = 95.0; double average = 0.0; string programHeader = "Welcome to my Grade Calculator!\n"; cout << programHeader; average = gradeOne + gradeTwo + gradeThree / 3; cout << "The Average is: " << average << endl;
