For C++ Driving is expensive. Given a car's miles/gallon and gas dollars/gallon (doubles), output the gas cost for 10 miles, 50 miles, and 400 miles. If the input is 20.0 3.1599, the output is: 1.57995 7.89975 63.198 (Note: Real per-mile cost would also include maintenance and depreciation).

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
