Just started this class and new to C++

using bew editor called CodeLite

Write a C++ program that will calculate and display the areas or some standard geometric figures. Specifically, the program needs to display the areas of the following geometric figures for length of side 1, 2, 3, 4, 5, and 6 (36 total results). You need to have a separate area function for each geometric figure. Each function needs to "protect itself" from a violation of its precondition. equilateral triangle square regular pentagon regular hexagon regular heptagon regular octagon
