Question

PLEASE READ AND CODE IN BASIC C++ CODE. ALSO, PLEASE CODE USING THIS DO WHILE LOOP AND FORMAT:

#include <iostream>
using namespace std;

int main() {
//variables here
  
do {
// program here
  
  
  
  
}while (true);
  
}

Objectives To learn to code, compile and run a program containing SELECTION structures Assignment Write an interactive C++.program to have a user input the length of three sides of a triangle. Allow the user to enter the sides in any order. Declare them as integers. 1. Determine if the entered sides form a valid triangle. The triangle may not have negative sides. The sum of any two sides must be greater than the third side to form a triangle. 2. Determine the type of triangle: equilateral triangle-3 sides are equal length isosceles-2 sides are equal length scalene-no sides are equal 3. Use the Pythagorean Theorem, determine if the scalene triangle is a right triangle. (A squared plus B squared equals C squared, where is the hypotenuse.) Adequately check entered data for validity. Use adequate test data to process all valid data and representative combinations of invalid data. Label output clearly. Be sure your output printout contains user prompts and what was entered by the user in addition to the results of your program processing. As discussed in class, add a simple do..while loop so that you can run all tests in one run. Minimum test data 3 4 5 1 2 0 7 -3 5 6 6 4 7 7 2 2 4 You may use additional test data, but you MUST use the previous test data as a minimum. Input--length of three sides of a triangle. Output Length of three sides; type of triangle; whether or not a triangle is a right triangle. Output an appropriate error message for invalid lengths entered for one or more sides or side lengths that cannot form a triangle. Turn in Program listing and program output (Showing all test data which includes valid and invalid data) Include an algorithm written in pseudocode. Extra credit: Declare the sides as doubles. Include isosceles triangles as possible right triangles.
