7. Write a program to find power of a number using for loop. Y = nx
8. Create a program that will calculate the factorial of any user entered integer. For any
positive integer, the factorial is given as: n! = n(n-1) (n-2)....... 3-2-1. The factorial
of 0 is 1. If a number is negative, factorial does not exist and this program should
display error message. Sample output dialogues should look like these:
Enter an integer: -5
ERROR!!! Factorial of a negative number doesn't exist
Enter an integer:
Factorial = 3628800
