To practice with variables, datatypes, and arithmetic
The speed of light in a vacuum is 186,000 miles per second. Create a C program that will prompt the user of the program to enter a number of days. Perform the arithmetic that is necessary to calculate how many miles light will travel in that number of days.
Make your program readable with good use of whitespace, good variable names, and comments where needed.
