This lab will give you practice using the String class we developed in lecture (as well as some more help with randomness and files). Program Information Allow the user the choice of displaying either a random line or a random word from a file they specify. Your menu should allow them to choose these options either from the number of the option or from the capitalized letter. For example, 1) display random Word 2) display random Line 3) Quit Should allow the user to select a random line display by either entering the number 2 or by entering a letter L (lower or upper case!).Number guessing Game Write a C program that implements the “guess my number” game. The computer chooses a random number using the following random generator function srand(time(NULL)); int r = rand() % 100 + 1; that creates a random number between 1 and 100 and puts it in the variable r. (Note that you have to include <time.h>) Then it asks the user to make a guess. Each time the user makes a guess, the program tells the user if the entered number is larger or smaller than its number. The user then keeps guessing till he/she finds the number. If the user doesn’t find the number after 10 guesses, a proper game over message will be shown and the actual guess is revealed. If the user makes a correct guess in its allowed 10 guesses, then a proper message will be shown and the number of guesses the user made to get the correct answer is also printed. After each correct guess or game over, the user decides to play again or quit and based on the user choice, the computer will make…
