#include #include #include #include #include /* Code By: Zeke Williams Date: Aug. 18, 2017 Description: This is a C++ drawing program that draws the shape you enter. Since I've been gone on a trip to Peru, I wanted something decent to show to let you know I'm back! Correction: I'll be back the 19th INPUT FORMAT*************INPUT FORMAT JUST HIT SUBMIT FOR A HEART! string = "square" int length_of_side example: square 7 string = "rectangle" int length int width example: rectangle 5 9 string = "triangle" int height example: triangle 8 string = "circle" int radius example: circle 12 string = "heart" string = "star" ************************************ Version: 1.2 Update: 1.1 - Added a 'heart' as available command! Just enter "heart" into the command list and be amazed :) 1.2 - Added a 'star' as a command! I give credit to Ace for this inspiration, so give him/her a like or two or check out their code! Just type heart into the input box to draw it. Update Plans: Add more shapes maybe Perhaps make classes to handle everything Add hollow parameter for each shape Remove the cout's I used for debugging in xcode Should I use a class for this? Maybe add that if it makes sense to do that */ struct DispChar { static const char dispChar = '*';// change the character that draws the shapes HERE!!!! }; void toLowerCase(std::string& input); bool inputIsValid(const std::string& input); unsigned int convertInputToInt(const std::string& input); void drawSquare(unsigned int d); void drawRect(unsigned int l, unsigned int w); void drawTriangle(unsigned int h); void drawCircle(unsigned int r); void drawHeart(); void drawStar(); int main(int argc, const char * argv[]) { std::string input = "heart"; std::cout << "Enter a shape you want drawn:\n"; std::cin >> input; std::cin.ignore(); toLowerCase(input); if (input == "square") { // SQUARE unsigned int sideLength; //std::cout << "Input length of the sides of the square: "; std::getline(std::cin, input); if (!(inputIsValid(input))) { std::cout << "\nPlease input a number next time!\n" << std::endl; } else { sideLength = convertInputToInt(input); if (sideLength > 25) { std::cout << "Limit is 25.
