en often play a memory game in which a deck of cards containing matching pairs is used. The cards are shuffled and placed face down on a table. The players then take turns and select two cards at a time. If both cards match, they are left face up; otherwise, the cards are placed face down at the same positions. Once the players see the selected pair of cards and if the cards do not match, then they can memorize the cards and use their memory to select the next pair of cards. The game continues until all the cards are face up. Write a program to play the memory game. Use a two dimensional array of 4 rows and 4 columns to use a deck of 16 cards with 8 matching pairs and you can use numbers 1 to 8 to mark the cards. (If you use a 6 by 6 array, then you will need 18 matching pairs, and so on.) Use random number generators to randomly store the pairs in the array. Use appropriate functions in your program, and the main program should be merely a call to functions.

Question

Children often play a memory game in which a deck of cards containing

matching pairs is used. The cards are shuffled and placed face down on a table. The players then take turns and select two cards at a time. If both cards match, they are left face up; otherwise, the cards are placed face down at the same positions. Once the players see the selected pair of cards and if the cards do not match, then they can memorize the cards and use their memory to select the next pair of cards. The game continues until all the cards are face up. Write a program to play the memory game. Use a two dimensional array of 4 rows and 4 columns to use a deck of 16 cards with 8 matching pairs and you can use numbers 1 to 8 to mark the cards. (If you use a 6 by 6 array, then you will need 18 matching pairs, and so on.) Use random number generators to randomly store the pairs in the array. Use appropriate functions in your program, and the main program should be merely a call to functions.

 

 

Extra credit:

Write a program that reads students’ names followed by their test scores. The program should output each student’s name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a struct variable of type studentType, which has four components: studentFName and studentLName of type string, testScore of type int (testScore is between 0 and 100), and grade of type char. Suppose that the class has 10 students. Use an array of 10 components of type studentType.

Your program must contain at least the following functions:

 

  1. A function to read the students’ data into the array.
  2. A function to assign the relevant grade to each student.
  3. A function to find the highest test score.
  4. A function to print the names of the students having the highest test score.

Your program must output each student’s name in this form: last name

followed by a comma, followed by a space, followed by the first name; the name must be left justified.
