(b)the expectation of how the system will work
(c)a system that is needed or wanted
(d) a best-case scenario for the final system
2. which of the following situations demonstrates a weakness of the systems development life cycle (sdlc)?
(a)the information systems department is finding the system difficult to maintain
(b)the manager cannot find documentation on the design process.
(c)the information systems staff cannot be changed because it would affect the development process.
(d)the client decides he or she wants to change the purpose of the project.
3. 3. which of the following is the worst reason to upgrade the operating system on your company’s computers?
(a)the new operating system has stronger security, so the company will not have to worry about data integrity

(b)planning; analysis; design; implementation; maintenance
(c)analysis; design; planning; implementation; maintenance
(d)planning; design; analysis; implementation; maintenance
7. which of the following situations demonstrates a strength of the systems development life cycle (sdlc)?
(a)the team is able to complete the project quicker than projects using other development methods.
(b)the cost of the project is relatively low.
(c)the client has lots of input on what will be in the final system
(d)the process set up by the team allows for lots of flexibility.
8. 8. during which phase of the systems development life cycle is the feasibility study conducted?
(a)analysis
(b)design
(c)implementation

Program using c++ only on visual studio pig is a simple two player dice game, played with one die. the first player to reach or surpass 50 is the winner. each player takes a turn rolling the dice. they add to the pot with each roll, having to decide to roll again and increase the pot, or cash out. the risk being they could lose the amount they’ve accumulated into the pot. the rules for each player’s die roll. 1. roll the dice. a. if user rolled a 1, i. the pot gets set to zero ii. the other player goes to step 1. b. a roll of 2-6 is added to the pot. 2. user can choose to hold or roll again. a. choice roll. return to step 1. b. choice hold. i. increment player score by the pot amount. ii. pot gets set to 0. iii. second player gets to roll and goes to step 1. program requirements: ● before each opponent begins ○ output the score for the person and the computer. ○ output the opponents whose turn is beginning and ask the user to hit enter to continue. ● with each dice roll. ○ output the die value, and amount of the round pot. ○ if it’s the users roll ask if they want to roll again ( r ) or hold ( h ). your program should allow r, r, h or h as valid input. if input is anything else, ask the user again until valid input is obtained. ○ the ai will continue playing until the round pot is 20 or more. ● once a player’s score is greater or equal to 50 then they have won, it will no longer ask if they want to keep rolling the die or not. ● once there is a winner ○ score totals are output along with who the winner was. user or computer ○ player is asked if they want to play again y or n. valid input should be y, y, or n, n. ● when a new game starts the starting roll goes to the player that did not roll last. if the user rolled last in the previous game, then the computer rolls first and vice versa. when the program first begins, the player will make the first roll of the first game. development notes : ● you will need a way to roll dice in your program. the rand() function works well, but returns an integer. if we want numbers 0 – 9 we can get the value modulus 10. ● call srand() with a value to seed it. it’s common to seed it with the current computer clock, include ctime, and then call srand(time(
