Write a program using C that computes factorial for any input number repeatedly until -7 is entered.

Example input and output:

Please enter number between 1 and 10 for factorial calculation (-7 to end) :5

factorial for 5 is 120

Please enter number between 1 and 10 for factorial calculation (-7 to end) :6

factorial for 6 is 720

Do not add any logic to limit the input. The limit between 1 and 10 is to keep the calculation and output simple.
