Draw the IPO chart for a program that reads a number from the user and displays the square of that number.
Answer:
See attachment for chart
Explanation:
The IPO chart implements he following algorithm The expressions in bracket are typical examples
Input
Input Number (5, 4.2 or -1.2) --- This will be passed to the Processing module
Processing
Assign variable to the input number (x)
Calculate the square (x = 5 * 5) Display the result (25) ----> This will be passed to the output module
Output
Display 25
Sure! The IPO (Input-Process-Output) chart for the given program can be represented as follows:
```
+----------+
| Input |
+----------+
|
|
|
V
+----------+
| Process |
+----------+
|
|
|
V
+----------+
| Output |
+----------+
```
Here's a step-by-step breakdown of each section:
1. Input: This is where the program reads the number from the user.
2. Process: In this step, the program calculates the square of the number.
3. Output: Finally, the program displays the square of the number to the user.
Please note that this IPO chart represents the high-level flow of the program.
To draw the IPO (Input-Process-Output) chart for a program that reads a number from the user and displays the square of that number, we need to define the inputs, process, and outputs of the program.
Inputs:
- User input: Number (input by the user)
Process:
- Calculate the square of the input number
Outputs:
- Display the square of the input number
IPO Chart:

Explanation on how to implement this program:
1. Prompt the user to enter a number.
2. Read the input number from the user.
3. Calculate the square of the input number by multiplying it by itself.
4. Display the square of the input number to the user.
Here is some code in Python that implements the program:
```python
# Prompt the user to enter a number
number = int(input("Enter a number: "))
# Calculate the square of the number
square = number ** 2
# Display the square of the number
print("The square of", number, "is", square)
```
This program will read a number from the user, calculate its square, and display the result.
