Line 48: You're trying to enter a character into a float. That's not valid.
Line 50,54,58: You're using the assignment operator (=), not the equality operator (==).
Line 70: You're trying to enter a string into an int. Not valid.
Line 73, 77: Again you're using the assignment operator, not the equality operator.
Also, if you want to compare strings, you need to use std::string and quotes, not '.
' is for character literals.
