Question

please help!

Write a program that can be used as a math tutor for a young student. The program should display two random numbers to be added. The program should then pause while the student works on the problem. When the student is ready to check the answer, he or she can press a key and the program will display the correct solution. The output must be formatted correctly with the numbers aligned properly. You will build on this assignment in future chapters Note: You will need to use the rand and srand functions. You must also seed the random number generator with something that appropriately changes each time the program runs just send the seed time to the sand function once and only once!) before using rand the first time. Also, you will need to set the minimum and maximum ranges of the numbers to fall between 50 and 500 thint, use this code: const int MIN-50, and const int MAX - 450.). Remember to include the two libraries time for using the time and cstdlib' to use the sand and rand functions #include<time> #include <stdlib> The output should look something like this: 196 Press Enter to see the answer... 196 625 Compile, run, and test your program. Make sure there are no errors and it functions properly. You can hit F5 to compile and run the program. Your program must run without errors to get full credit Upload attach) your cop file here for grading. It must be named correctly and saved as a readable cpp file with the proper extension

I have given you the code with comments,and also code images and the output, Hope this helps
