2) for both triangle and diamond, first display a triangle of requested size, and then if the choice is a diamond, add the bottom part 3) displays the shape We want to create a program that draws a diamond or a triangle with a size that the user selects using a specific character that will be entered at the keyboard. Here are two examples: To write this program, we will assume that we have the following functions: 1) void instructions() II This function describes the program and how it works A triangle of size 4, using *: 2) int menu() I // This function will return a choice to the main ; 1) draw triangle, 2) draw diamond, and 3) quit 3) draw_shape(int choice) I/ This function calls on appropriate function depending on the choice to draw a shape A diamond of size 4, using *: 4) int get_size() II This function will return the size of the shape, same function for either of the shapes *** 5) char get_char() // This function will ask users to select a character that will be used to draw the shape *** What do we need for this program? 6) void draw_triangle(int size, char c) I/ This function draws a triangle of size size using character e Problem definition We first need to clearly define the problem, the inputs and the outputs. Inputs: 1) a choice to draw one of the two shapes or to quit the program, 2) a character choice which will be used for drawing the selected shape, and 3) the size of the shape 7) void draw diamond(int size, char c) II This function first calls draw_triangle, then draw_bottom to draw the diamond 8) void draw_bottom(int size, char c) II This function actually draws an upside down triangle of size size-l as the bottom of the diamond Output: One of these will be the output: 1) a triangle, 2) a diamond, 3) quit Now that we have defined the functions, it is time to design the algorithm for the program. However, we can write the main part of the program. Analysis of the problem We need to break down the tasks that this program is supposed to complete. The main tasks are: 1) ask for the input data int main () { int choice;
