| the factorial of non-negative integer n is written n! and
is defined as follows:
n!=n*(n-1)*(n-2)........1(for values of n greater than or
equal to 1 and
n!=1(for n=0)
Perform the following
1.write a c program that reads a non-negative integer and
computes and prints its factorial.
2. write a C program that estimates the value of the
mathematical constant e by using the formula:
e=1+1/!+1/2!+1/3!+....
3. write a c program the computes the value ex by using the
formula
ex=1+x/1!+xsquare/2!+xcube/3!+....
