Question

I am taking a Data Structures and Program Design class. BUT, I am having trouble getting access to the vectors so that I can compare the guesses with the random numbers. I’ve been working on this for several days and don't feel any closer to a solution and could really use some help as I really don't know how to get this to work. Thank you!

The assignment is:

Design an ADT for a one-person guessing game that chooses 4 random integers in the range from 1 to 9 and asks the user to guess them. The same integer might be chosen more than once. For example, the game might choose the following four integers that range from 1 to 9: 4, 6, 1, 6. The following interaction could occur between the user and the game:

Enter your guesses for the 4 integers in the range from 1 to 9 that have been selected:

User Input: 1 2 3 4

2 of your guesses are correct. Guess again.

User Input: 2 4 6 8

2 of your guesses are correct. Guess again.

User Input: 1 4 6 6

You are correct! Play again? No

Good-bye!

Submit header file guess.h, implementation file guess.cpp, main function file main.cpp You need to include a makefile, and Readme file (see Programming Guidelines).

output:

I have fixed your code and mentioned the error in the code. some of your functions are ambiguous , can delete it if it has no further use.

if you have any issues please do comments . if you found this solutions useful, please give me thumbs up.
