Extracted text: 4. Write a simple factorial calculator program. The program should perform the following: Step 1. Ask the user to enter a positive integer. Step 2. Check if the entered integer is positive or negative. If it is positive, perform Step 3; otherwise, display an appropriate error message and the program should stop. Step 3. Calculate the factorial of the entered positive integer and display the result. Note: The factorial of n is denoted by n! and calculated by the product of integer numbers from 1 to n. For example, the entered integer is 5, the calculation of its factorial is: 5! = 1 x 2 x 3 x 4 x 5 = 120. Step 4. Repeat Step 1 to Step 3 five (5) times. 5. Compile and execute the program. 6. Debug syntax and logical errors if there is any in the program. 7. The following is an example output: Factorial Calculator -- Enter a positive integer: 5 5! = 1 x 2 x 3 x 4 x 5 The factorial of 5 is: 120 Enter a positive integer: 4 4! = 1 x 2 x 3 x 4 The factorial of 4 is: 24 Enter a positive integer: -5 Invalid input! Program stopped! Figure 1: Example output with entered negative number
