I need some help with my homework please
Write a C++ program to prompts the user to enter the first character of shape name (Cycle, Rectangle, or Triangle). Then calculate the area of that shape.
„h If the user enters another character the program should print: You should insert C || c, R || r, or T || t „h
Output
Note:
1- Using Nested if ¡V else statements ). 2- Using Switch Structure
There are three seating categories at a stadium. For a softball game, Class A seats cost $15, Class B seats cost $12, and Class C seats cost $9. Write a program that asks how many tickets for each class of seats were sold, then displays the amount of income generated from ticket sales. Format your dollar amount in a fixed-point notation with two decimal points and make sure the decimal point is always displayed.
Sure! I can help you with that.
To solve this problem, we can use either nested if-else statements or a switch structure. I'll explain both approaches to you, and you can choose the one you prefer.
Approach 1: Using Nested if-else statements
1. Start by prompting the user to enter the first character of the shape name.
2. Read the user's input.
3. Use nested if-else statements to determine the shape and calculate its area:
a. If the user enters 'C' or 'c', it represents a circle.
- Prompt the user to enter the radius of the circle.
- Read the radius.
- Calculate the area of the circle using the formula "area = pi * radius * radius" (assuming you have already defined the constant pi).
b. If the user enters 'R' or 'r', it represents a rectangle.
- Prompt the user to enter the length and width of the rectangle.
- Read the length and width.
- Calculate the area of the rectangle using the formula "area = length * width".
c. If the user enters 'T' or 't', it represents a triangle.
- Prompt the user to enter the base and height of the triangle.
- Read the base and height.
- Calculate the area of the triangle using the formula "area = 0.5 * base * height".
d. If the user enters any other character, display the message "You should insert C || c, R || r, or T || t".
Approach 2: Using Switch Structure
1. Start by prompting the user to enter the first character of the shape name.
2. Read the user's input.
3. Use a switch structure to determine the shape and calculate its area:
a. If the user enters 'C' or 'c', it represents a circle.
- Prompt the user to enter the radius of the circle.
- Read the radius.
- Calculate the area of the circle using the formula "area = pi * radius * radius" (assuming you have already defined the constant pi).
b. If the user enters 'R' or 'r', it represents a rectangle.
- Prompt the user to enter the length and width of the rectangle.
- Read the length and width.
- Calculate the area of the rectangle using the formula "area = length * width".
c. If the user enters 'T' or 't', it represents a triangle.
- Prompt the user to enter the base and height of the triangle.
- Read the base and height.
- Calculate the area of the triangle using the formula "area = 0.5 * base * height".
d. If the user enters any other character, display the message "You should insert C || c, R || r, or T || t".
Remember to include the necessary header files, define constants, and print the calculated area as the output.
I hope this explanation helps you in writing your C++ program. Let me know if you need any further assistance!
