Ok so I am having a really hard time with just the last part of my code.

If y is entered then the whole code should repeat itself.

If n is entered then the program should stop (THAT IS WHERE I AM HAVING THE HARDEST TIME TO GET THE PROGRAM TO STOP ALL TOGETHER I KEEP GETTING AN ERROR)

And if a letter other than y or n is entered then the code has to continuously ask to enter a valid input.

Please make sure your code works by trying it out, thank you!

while (letterToContinueOrStop != 88 letterToContinueOrStop !'n') { rintf("Enter a valid inputln"); rintf( ("Hould you like to perform another calculation? (y)" scanf(" %c", &letterToContinueOrStop); rintf("In"); while (letterToContinueOrStopy return main)
