1 Calculate Areas calculateAreas.cpp contains several functions: calculateSquare, calculateCircle, calculateRight Triangle, printResult, and runProgram. runProgram is a void function with no parameters. It is simply the function that the main function will call. printResult will take two arguments: the shape whose area is to be printed and the value of that shape's area. It will print the result of the given calculation. calculateAreas will display a menu to the user, read in the user's choices based on the menu, act on the user's choices, and (eventually) end the program when the user decides. calculateSquare will take the length of a square's side as an argument and return the area of a square with that given side length. The formula for the area of a square is A = s where A is area and s is the side length. Figure 1: Square of area 36 calculateCircle will take the length of a circle's radius as an argument and return the area of a circle with that given radius. The formula for the area of a circle is A = x where A is area, r is the radius length, and is defined as MPI in the cmath library. O Figure 2: Circle of area 36m calculateRight Triangle will take the length of a right triangle's base and the height of a right triangle and return the area of a right triangle with those given dimensions. The formula for the area of a right triangle is A = xbxh where b is the length of the base of the triangle and h is the height of the triangle.
