double dNan = Double.NaN; A double value must be cast to the integral type before it is assigned to a variable of any integral data type (int, long, byte, short, or char).
Thedoubledata type is commonly used in situations that require a large range of values or a high degree of precision, such as scientific calculations, financial applications, and complex mathematical computations. The range fordoublevalues is approximately from 4.9e-324 to 1.7e+308. ...

指定元素区间(range),这可以通过传递两个指针来完成:一个指针标识数组的开头,另一个指针标识数组的尾部。 #include <iostream> const int ArSize = 8; int sum_arr(const int * begin, const int * end); int main() { using namespace std; int cookies[ArSize] = {1,2,4,8,16,32,64,128}; /...
