Term by CodeChum Admin (JAVA CODE) Construct a class called Term. It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term. The second line contains the coefficient and the exponent of the second term. 1·1 4·3 Output Display the resulting product for each of the test case. 4x^4

# Coding - Simulate a robot Write a program that simulates the movements of a robot. The robot can have three possible movements: turn right turn left advance The robot is placed on a hypothetical infinite grid, facing a particular direction (north, east, south, or west) at a set of `{x,y}` coordinates,e.g., `{3,8}`, with coordinates increasing to the north and east. Create a Class `Robot` that contains a method `execute` which given a number of instructions will calculate the robot's new position, and the the direction in which it is pointing. ## Example The letter-string "RAALAL" means: Turn right Advance twice Turn left Advance once Turn left yet again Say a robot starts at `{7, 3}` facing north. Running this stream of instructions should leave it at `{9, 4}` facing west. ## Inputs and Outputs The argument of the `execute` is `string` in the format `X Y BEARING COMMANDS`. The method should return a one-liner `string` in the format `X Y BEARING`. In the…

Bookstore class uses a dynamic array to hold names book titles. class BookStore { public: BookStore (); BookStore (const Bookstore & b); // POST: object made from b -BookStore (); void insert(string title); // POST: add title to the end of the titles list private: string store; int capacity; int size; }; Describe two different situations in which the copy constructor function is called. Write a short code snippet illustrating each situation. Explain the problem if this class did not provide a deep copy constructor function. // POST: empty object with room for 10 titles // POST: object is destructed // pointer to dynamic array of book titles // capacity of array // number of books used in the bookstore

Error check and validate to ensure a legal integer was entered. If not, clear the cin buffer using clear() and ignore() and try again (Note: the buffer still needs to be cleared even if this step was successful). If a legal integer was entered, check its value to see if it is within the…
