Here I go again this class is killing me, the instuctor is a nice guy and all is's just he really doesn't explain things well. This is what I have to do and I can't get started. The problem is there are no examples at all on factorial programs in the book and all the instuctor does is show a Power Point at the beginning of class and then gives us this and says now write this. I know it's very elementry I'm just not getting it.

1.) Write a program using FOR control statement to print the factorial of a number n. Factorial of positive number n in n*(n-1) *(n-2) *(n-3)...
For example:
Factorial of 5 is ( 1*2*3*4*5) = 20
Factorial of 4 is ( 1*2*3*4*5) = 24

2.) Your program should do the following
a. Ask the user to enter a positive integer.
b. Read the integer and print out the factorial of the number.
c. Ask the user if he/she wants to coninue.
d. If yes, repeat steps a,b,c, if no quit the program.

The structure of a for loop is
The initialization is usually "int i = 0" or something of that form, i being the variable that will be used to count the loop's iterations. The code in the loop runs, and then if condition is still true, increment (stereotypically "i++") is run and the loop code is run again, and then condition is checked...

For factorial, it looks like you need to declare a variable outside the loop to hold the factorial, then loop from 1 (initialize i to 1) up to the number (the condition could be "i < number" and in the loop multiply the factorial by i. Note that your examples are incorrect. They should read
Factorial of 5 is ( 1*2*3*4*5) = 120
Factorial of 4 is ( 1*2*3*4) = 24

Once you've tackled the factorial part, work on the continue part. (Very) slightly more advanced: since the multiplicative identity property says that n*1==n, always and forever, can you optimize the loop?
