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! %3D 1 х 2 х 3x4 х5 The factorial of 5 is: 120 Enter a positive integer: 4 |4! %3D 1 х 2 х 3х 4 The factorial of 4 is: 24 Enter a positive integer: -5 Invalid input! Program stopped! Figure 1: Example output with entered negative number

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sort…
