Use the following scenario to answer the following questions: Adriana is creating a point-of-sale (cash register) application for Fourth Coffee. Her responsibility is to create a password-protected login system to ensure security of the system. She has finished the login window and password check, but she is having trouble implementing it correctly. Adriana's project manager wants the system to give the user three attempts to login correctly before locking the system. In Adriana's most recent version, the system prompts the user for a name and password three times—even if the user correctly logs in on the first try. After the third attempt, the system always locks—even if the input is correct. 8. Adriana is using a for loop, which works best when: a. the number of iterations is known and is unlikely to change during execution b. the number of iterations is known but is likely to change during execution c. the number of iterations is unknown

SCENARIO: Ken is a soccer coach who has a difficult time keeping track of all of his players: At the beginning of the season, each of his players filled out a paper with personal data, but it always takes him a long time to find the information he needs. Cassie is one of his brightest players, and Ken knows that she's a computer programmer. Tired of shuffling through the huge stack of papers, he asks her to create a program to keep track of his records. The program will need to store each player's full name, jersey number, age, gender, height and weight, as well as goals scored and number of games played. Cassie agrees to develop the software for him, but she has some decisions to make . . . 10. Would you have to use the Convert.ToInt32 code for any of the variables collected? a. True b. False

4. You are developing a C# program. You write the following code: 01: int count = 0; 02: while (count < 5) 03: { 04: if (count == 3){ 05: break; 06: } 07: count++; 08: } How many times will the control enter the while loop? a) 5 b) 4 c) 3 d) 2

3. You are developing a C# program that needs to perform 5 iterations. You write the following code: 01: int count = 0; 02: while (count <= 5) 03: { 04: Console.WriteLine("The value of count = ", + count); 05: count++; 06: } When you run the program, you notice that the loop does not iterate five times. What should you do to make sure that the loop is executed exactly five times? a) Change the code in line 01 to int count = 1; b) Change the code in line 02 to: while (count == 5) c) Change the code in line 02 to while (count >= 5) d) Change the code in line 05 to count++;
