C++ prgramming
There is a memory game that children play in which a deck of cards containing matching pairs is used. The cards are shuffled and placed face down on a table. The players 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 position. 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 by 4 columns with a deck of 16 cards (8 matching pairs). Use the random number generator to store the cards into the array. Use matching pairs of letters (A through H) for the card names. For cards not turned overuse '*'. Display the array and ask the user to select two cards by giving array's row and column. Display the array with the two cards exposed. If the two cards don't match, tell the user and then display the array again with the two cards no longer turned over. If the two cards do match, leave them exposed. Play continues until all cards are exposed.
//My problem: How can I display matching pairs of letters (A through H) for the card names.
