Assignment 04

Sooooo, your code will generate (at this time) passwords that have 9 characters rather than only 4 letters. Also, security is compromised by the fact that the character set is limited to alphabetics. Homer wants your program to randomly inject digits into the passwords. Thus, for every time your code generates a new character, there is a 50-50 shot that it is a randomly chosen digit between and including 0 and 9.

Specifications: You are to modify the solution posted for HW #1 (NOT your own solution for HW #1!) to use functions according to the specifications listed below.

1. Make a function to output the welcome message. There should be no parameters or return value for this function.

2. Make a function that will prompt for and get input for a short integer, validating the input. The parameters to this function should be a string prompt (which will be output to the screen), a short minimum value, and a short maximum value. The latter two parameters constitute the valid range of input values (inclusive) the user is allowed to enter. This function should return the (validated) short integer that the user entered.

3. Make a function to calculate a single character of the password. The parameters to this function should be the user’s age, brain weight, whether or not s/he is a glue eater, and the current value of the kFactor. The return value of this function should be the calculated character.

4. Make a function to output the sign-off message. There should be no parameters or return value for this function.

You are to use the above functions in your program. If you want to make other functions, you may do so. But your program should appropriately utilize these functions to perform the task described in HW #1. The function you write for (2) above should be used to get (each of) the inputs for age, brain weight, and whether or not the user regularly eats glue. The minimum and maximum values for age are 1 and 100, respectively. The minimum and maximum values for brain weight are 0 and 10, respectively. And, you will of course loop on the execution of function #3 above. Also, increment the kFactor only if you generate a character, not if you put in a digit.

By the time you submit this program, we will have covered multiple files in the lecture. However, you are to do this program in a single file only. As you were shown, put global constants and prototypes above main, and put function definitions below main. Also, you will be required to give full documentation of your functions (description, pre-, and post-conditions). That material will be covered very soon in your lecture.
