| 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!+....

| a number is perfect if it is equal to the sum of its proper
divisor..
6 is perfect number coz its proper divisors are 1,2 and
three.. and 1+2+3=6...
a number is deficient if the sum of its proper divisor is
less than the number..
sample: 8 is deficient, coz its proper divisors are 1,2 and
4, and 1+2+4=7.
abundant number, if the sum of its proper divisor is greater
than the number..
sample..12 is abundant coz 1+2+3+4+6=16 which is geater than 12.
now write a program that prompts the user for a number, then
determines whether the number is perfect,deficient and
abundant.. | | 1 |
