// Please follow all the instructions Each of the class declarations and/or member function definitions below has syntax error(s). Find every error. All errors with explanation and fix the code. * Hint: You may use compiler to help you find the error. However, you need to set up the program correctly and to point out the true cause of the syntax error. Because the compiler messages are convoluted, due to the convoluted nature of language dependencies. 54. class Truck, public...
