Why is the definition not placed in the header file?The reason is that variables with external links cannot be defined. Because there are multiple compilation units, multiple definitions are found at the time of the link, and the linker cannot

In C, the pointer is a type, storing the address, for example, Char*p, where p holds the address of the character data, int*p,p store the address of the shaping data, we can use the solution to get the address point to the content. An array is a

The accessor of a property contains an executable statement about the GET or set property. An accessor declaration can contain either a get accessor or a set accessor, or both. The declaration takes one of the following forms:get {}set {}Get
