The National Weather Service calculates windchill index by using the following formula:
35.74 + (0.6215 * t) - (35.75 * v^.16) + (.4275 * t * v^.16)
Write a program which prints nicely formatted table of windchill values. Rows must represent wind speed for 0 to 50 in 5 mph increments, and columns represent temperatures from -20 to +60 in 10-degree increments
