The code should be written in C++ with comments.

Option 1: Write a program that will convert miles to kilometers and kilometers to miles. The user will indicate both a number (representing a distance) and a choice of whether that number is in miles to be converted to kilo- meters or kilometers to be converted to miles. Each conversion is done with a value returning function. You may use the following conversions. 1 kilometer = .621 miles 1 mile = 1.61 kilometers Sample Run: Please input 1 Convert miles to kilometers 2 Convert kilometers to miles 3 Quit 1 Please input the miles to be converted 120 120 miles 193.2 kilometers Please input 1 Convert miles to kilometers 2 Convert kilometers to miles 3 Quit 2 Please input the kilometers to be converted 235 235 kilometers 145.935 miles Please input 1 Convert miles to kilometers 2 Convert kilometers to miles 3 Quit 3
