Introduction to Template

A template in C++ programming helps to pass data type as a parameter to make the code reusable. The goal is to write a generic code that can be reused for specific types depending upon the need.

First programming homework Create a class of records for a gradebook called Rec. The data should be private, and should include a firstname, lastname, array of three grades, and a field for average grade. Build two constructors: a default constructor and a constructor that takes the first and last name. Build a function to read the data, either from a file or from cin. The read function reads the two names and three grades, but does not read the average grade. Build a write function that writes the data either to a file or to cout. The write function prints all of the data on one line with spaces between fields. Build a function to calculate the average grade field. Build an overloaded operator == to compare two records. This should be implemented as a friend function. Declare the constructors and functions in the body of the class, but implement them outside the class.

Game of Hunt in C++ language Create the 'Game of Hunt'. The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…
