1. Construct a flowchart for this C/C++ program:
To construct a flowchart for this program, we need to break down the steps and decisions involved in calculating the area or volume for different shapes.
- Start
- Ask the user whether to calculate the area or volume
- If area, go to 2-D shapes
- Ask for the type of 2-D shape (triangle, square, rectangle, circle, or trapezium)
- Ask for inputs of required dimensions (base, height, side length, etc.)
- Calculate the area using the specific formula for the chosen shape
- Display the calculated area
- If volume, go to 3-D shapes
- Ask for the type of 3-D shape (cuboid, cylinder, cone, or sphere)
- Ask for inputs of required dimensions (length, width, height, radius, etc.)
- Calculate the volume using the specific formula for the chosen shape
- Display the calculated volume
- End
2. Develop a pseudocode for this C/C++ program:
To develop pseudocode for this program, we can follow the steps outlined in the flowchart.
```
start
ask user whether to calculate area or volume
if area
go to 2D shapes section
else if volume
go to 3D shapes section
2D shapes section:
ask user for the shape type (triangle, square, rectangle, circle, or trapezium)
ask user for the required dimensions based on the shape type
calculate the area using the specific formula for the chosen shape
display the calculated area
3D shapes section:
ask user for the shape type (cuboid, cylinder, cone, or sphere)
ask user for the required dimensions based on the shape type
calculate the volume using the specific formula for the chosen shape
display the calculated volume
end
```
3. Construct a hierarchy (structure) chart for this C/C++ program:
The hierarchy chart shows the structure of the program and how the different modules or functions are connected to each other.
```
Main Program
- Ask User
- Calculate 2D Area
- Calculate Triangle Area
- Calculate Square Area
- Calculate Rectangle Area
- Calculate Circle Area
- Calculate Trapezium Area
- Calculate 3D Volume
- Calculate Cuboid Volume
- Calculate Cylinder Volume
- Calculate Cone Volume
- Calculate Sphere Volume
- Display Result
```
4. Construct an IPO chart for this C/C++ program:
The IPO chart shows the inputs, processing, and outputs for each module or function in the program.
```
Calculate 2D Area
Inputs: 2D Shape Type (string), Dimensions (varies based on shape type)
Processing: Calculate Area using specific formula for the chosen shape
Output: Area (float)
Calculate 3D Volume
Inputs: 3D Shape Type (string), Dimensions (varies based on shape type)
Processing: Calculate Volume using specific formula for the chosen shape
Output: Volume (float)
