这是通过传递vector地址做到的。malloc返回的地址被赋给arr。解引整数指针的指针得到的时整数指针。因为这是vector的地址,所以我们修改了vector。 注:因为vector本身就是int *,如果想传递值的话参数本身就应该时int *,要想传递指针就应该时int **。 错误版本: voidallocateArray(int*arr,intsize,in...

To avoid these kinds of leaks and exception problems altogether, use the mechanisms that are provided by the C++ Standard Template Library (STL). These include shared_ptr, unique_ptr, and vector. For more information, see Smart Pointers and C++ Standard Library. See Also try-finally Statement...
In previous versions, <math.h> defined some, but not all, of the C++ overloads for the math library functions. The rest of the overloads were in the <cmath> header. Code that only included <math.h> could have problems with function overload resolution. Now the C++ overloads have ...
