Copy the following code over to a C++ file to create the structure: struct IsoscelesTriangle { float firstSide; float secondSide; float thirdSide; } In your main function, write code that implements the following steps: 1. Display a welcome message, Welcome to the Triangle Evaluation Program. 2. Request the dimensions for each of the three sides of a triangle. Store each side in an instance of the structure, IsoscelesTriangle. 3. Evaluate the triangle to determine if it is an isosceles triangle or not and, and display output to indicate to the user the result of this evaluation. (Hint: Isosceles triangles are triangles where exactly two sides of the triangle are the same length).
