Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65 The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.

WebAug 23, 2012 · Anyway I don't understand what you actualy want - in the title you say you want to "turn off std::fixed" (you can do that by using std::scientific) and then you say you want just two decimal places in output (which you'll get if you just use the right precision, i.e. 2 instead of 16). – WebWrite a program with a car's miles/gallon and gas dollars/gallon (both doubles) as input, and output the gas cost for 20 miles, 75 miles, and 500 miles Output each floating point value with two digits after the decimal point, which can be achieved by executing cout << fixed << setprecision (2): once before all other cout statements. robot compliance
