Writing code for a program in C

sure · #1 08-Jun-2005, 18:37

Tryin to learn c prog on my own at home.... havin a hard time with a few of the review Q's

What i need to do:

The factorial of a non-negative integer n is written n! (pronounced "n factorial") and is defined as follows:
n! = n * (n-1) * (n-2) * ... * 1 (for values of n greater than or equal to 1)
and
0! = 1
For example 5! = 5*4*3*2*1, which is equal to 120.

Write a program that inputs a non-negative integer and computes and prints its factorial. Use a "while loop" as part of your program implementation. only between 0 and 12 .

heres my psudocode

Code:

/*	
    PSEUDO CODE FOLLOWS:

    General Statement 

		Compute factorials between 0 and 12

	First Refinement

		1) Initialize Variables
		2) Compute the factorial in a while loop 
		3) Calculate and print the factorial result

	Second Refinement

		1) Factorial = 1
		   
		2) Input num 
           Do print "Enter a positive integer less than 13 
	          input value for n 
	          while ( n<0 || n>12 )

		3) Counter = n
				while (counter>1)
				factorial = factorial*counter
				counter = counter - 1

   END OF PSEUDO CODE
*/

thx ...

You should read the sticky. You forgot an important posting point, namely you have to ask a question and/or tell us the trouble you are having.
