The factorial of a nonnegative 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 to 1)
and
n! = 1 (for n = 0 or n = 1).
For example, 5! = 5 · 4 · 3 · 2 · 1, which is 120. Use while
structures in each of the following:
a) Write a program that reads a nonnegative integer and
computes and prints its factorial. Use the
following function prototype to calculate factorial:
int myFactorial(int n);
b) Write a program that estimates the value of the
mathematical constant e by using the formula:
Use the following function prototype to calculate e:
double myE( );
Hint: Use an accuracy of 10 terms.
c) Write a program that computes the value of ex by using
the formula
Use the following function prototype to calculate e:
double myEx(int x);
