以有組織的方式計算嵌套的for-loops

Question

The wind chill index combines the temperature and wind speed to tell us how cold the wind makes it "feel." The new wind chill index (often called the 「wind chill factor」) used by the US and Canadian weather services is determined by iterating a model of skin temperature under various wind speeds and temperatures. The results of this model may be approximated, to within one degree, from the following formula. windchill = round(35.74 + 0.6215 * T – 35.75 * S 0.16 + 0.4275 * T * S 0.16) Where T is the temperature in degrees Fahrenheit, and S is the wind speed in miles per hour. Write a program that will produce the following wind chill table. You must use a nested loop.

我在做什麼錯？

我回來錯誤背靠背。謝謝！

如果‘cout’ was not declared in this scope是唯一的錯誤，那麼您的修復程序就在這裏。

添加using namespace std;到您的文件的開頭（後包括）或使用std::cout代替cout。
