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 × 2 × 3 × 4 × 5 = 120. Step 4. Repeat Step 1 to Step 3 five (5) times. 5. Compile and execute the program.
