‘while’ statement ??

[SilviaJamieson]

Hi, as i said i am new to all this computer stuff, I think that if i can see how codes are written a few times, then i can start to understand it better. Please help me to better understand this language.

Write a C program using a while-statement to compute n factorial (n!) of a nonnegative integer n where
p = 1 (for n = 0)
p = double = n*(n-1)*(n-2)*…*2*1 (for n€1)
„ For example : 5! = 5*4*3*2*1 = 120
„ Prompt user to enter the value of n, computes
and prints its factorial (p)
