Create a file named diamond.cpp$.$ Write a program that prompts the user for an integer, and then prints an ASCII art diamond where each side is made up of that number of slashes:

$[$alice@wonderland lab$2]$$ $./$diamond

Side length:

$3$

$/\backslash$

$/\backslash$

$/\backslash$

$\backslash /$

$\backslash /$

$\backslash /$

The left corner of the diamond should always be flush against the left edge of the console. Use spaces for indentation, but only where necessary: there should be no spaces to the right of the diamond. If the user enters a number less than one, there should be no further output.
