C13-14 The problems in this problem set cover lectures C13 and C14 1. a. Define a robust algorithm to carry out integer division using repeated subtraction. Your algorithm accepts two integers and returns the quotient and the remainder. Hint : What are the preconditions and postconditions of your algorithm? b. Implement your algorithm as an Ada95 program, using exception handling to provide robustness. Turn in a hard copy of your algorithm and code listing, and an electronic copy of your code. 2. a. What is the cyclomatic complexity of the code fragment shown below?
