Concentration Program in C Language [closed]

Modify the Concentration Game to use a main menu. The menu should allow the user to select a level of difficulty and/or quit the game (a sample menu is shown below). The level of difficulty could be determined by how many separate numbers the user has to concentrate on and/or how many seconds the player has to concentrate. Each time the user completes a single game of Concentration, the menu should reappear allowing the user to continue at the same level, at a new level, or simply quit the game. 1 Easy (remember 3 numbers in 5 seconds) 2 Intermediate (remember 5 numbers in 5 seconds) 3 Difficult (remember 5 numbers in 2 seconds) 4 Quit
