Factorial?
Please support our C++ advertiser: Intel Parallel Studio Home
 |
can anyone come up with a solution for this ? real quick for me?
the factorial of a nonnegative integer n is written n! ("n factorial") and is defined as follows: n!=n*(n-1)*(n-2)*.....*1(for values of n greater than to 1)
and n!=1 (for n=0 or n=1).
For example, 5!=5*4*3*2*1, which is 120. Use a while structure for the following..write a program that reads a nonnegative integer and computes and prints its factorial.
If anyone could this for me thanks.

Untested, this might work.

What output does it give?
Try int x;
int factorial=1; on two separate lines?
Try int x;
int factorial=1; on two separate lines?

Oops! Just realized
the last line should cout << factorial
not cout << x
edited post above to fix error

You're missing a } to end the if statement.

If you can't do the course go find something more suitable.
