You are asked to write a Typing tutor program. This program should teach typing in which a sentence appears on the screen and the user must type it out within a certain amount of time or achieve a certain number of words per minute throughout a beginner level. Your program should have 5 sentences consisting of 8-12 word each. Each time a user plays the game a random sentence will be selected from array of strings After the user types the sentence, the program prints the time it took the user to print the sentence, number of errors (mismatch), number of words typed per sec. Also describe what test cases you used to check the validity of your system (you might have more cases). 1. Entering a correct sentence. 2. Entering incorrect sentence. 3. Not completing the sentence/ entering longer sentence. 4. Exceeding the time allowed You should submit your OWN code. i.e. you are not allowed to copy from the internet, any other person or references. You need to do a demo in my office to grade your assignment
