I have done a program, it works but i used a book to help me as i was seriously stuck and unsure what i have actually done in fields

"register an integar" as i normally put int iCount (iCount my integar i nominate)

"Long factorial"

and "Return 0" as i use getch(); normally

My code:

Code:

#include<stdio.h>

int main()

{

register int count;                         

int iCount;                                

long factorial;

printf("Compute the factorial of what number?");               

scanf("%d",&iCount);

for (factorial =1L, count=1; count<=iCount; count++)

        factorial *=count;

printf("%d!=%d\n",iCount, factorial);                    

return 0;                                                                                                                

}

So what you could not understand?

The lines that i wrote
"register an integar"

"Long factorial"

"Return 0"

I would usually make a comment after each for my understanding,

eg.

if i wrote

getch(); // get a character from the keyboard

something along those lines

Code:

register int count; // declare the first counter  

int iCount;        // declare the second counter        

long factorial; // Declare the var for output 

printf("Compute the factorial of what number?");   // display message to user

scanf("%d",&iCount); // Get the input from user

// Loop through to multiply the numbers to calc fact

for (factorial =1L, count=1; count<=iCount; count++)

        factorial *=count;

printf("%d!=%d\n",iCount, factorial);  // Print output

Thank you so much, cleared it all up for me.
