Driving is expensive. Write a program with two inputs, a car's miles/gallon and the cost of gas/gallon both represented as double variables, and output the total drive cost for 10 miles, 50 miles, and 400 miles, all on the same line, each separated by a single space. Output each floating-point value with two digits after the decimal point, which can be achieved by executing the command
cout << fixed << setprecision(2); once before all other cout statements. That is done only once in the code before any cout stamtent.

Ps:(when i run the program it says this-
Enter miles per Gallon:
Gas cost for ten miles :-nan
Gas cost for fifty miles :-nan
Gas cost for four hundred miles:-nan

Write a program called assignment3 (saved in a file assignment3.java) that computes the greatest common divisor of two given integers. one of the oldest numerical algorithms was described by the greek mathematician, euclid, in 300 b.c. it is a simple but very e↵ective algorithm that computes the greatest common divisor of two given integers. for instance, given integers 24 and 18, the greatest common divisor is 6, because 6 is the largest integer that divides evenly into both 24 and 18. we will denote the greatest common divisor of x and y as gcd(x, y). the algorithm is based on the clever idea that the gcd(x, y) = gcd(x ! y, y) if x > = y and gcd(x, y) = gcd(x, y ! x) if x < y. the algorithm consists of a series of steps (loop iterations) where the “larger” integer is replaced by the di↵erence of the larger and smaller integer. this continues until the two values are equal. that is then the gcd.

David is in week 3 of his current ashford course and has a paper due by monday night at midnight. he has finished everything but the concluding paragraph. as he boots up his computer to work on it, he sees a flash across the screen and then the screen goes black. he begins to panic as he tries desperately to turn the laptop back on. david should have saved his work on what kind of portable device?
