数组的初始化的格式出了问题，需要花括号{},或者花括号没有写对。
3.Initializing An Array In C++ Separately Using Loops Arrays can also be initialized after their declaration using loops. This method is especially useful for dynamic initialization, where values may be determined at runtime. int arr[5];
C language Initialization Wheninitializingan object ofarraytype, the initializer must be either astring literal(optionally enclosed in braces) or be a brace-enclosed list of initialized for array members: =string-literal(1) ={expression,...}(2)(until C99) ...
A designator causes the following initializer to initialize of the array element described by the designator. Initialization then continues forward in order, beginning with the next element after the one described by the designator. int n5 = {4=5,0=1,2,3,4} // holds 1,2,3,4,5 int aMAX...
Under the hood, on ELF platforms, the initialization functions or constructors are implemented in two schemes. The legacy one uses.init/.ctorswhile the new one uses.init_array. .section .text.startup,"ax",@progbits _GLOBAL__sub_I_a.cc: ...
Using an additional = character would result in confusion in syntax between that of assignment of a new instance of the collection type and initialization of members to the collection. So using a keyword rather than a = character to determine the result of a Collection Initializer action avoids ...
In the previous example, notice that with implicitly typed arrays, no square brackets are used on the left side of the initialization statement. Also, jagged arrays are initialized by usingnew []just like single-dimensional arrays. When you create an anonymous type that contains an array, the ...

Agreed. I wasn't aware of this change in static member variables but it is logical and is a necessary extension with constexpr to also prohibit separate initialization. I guess this is one of the remaining bugs that has C++11 implementation of constexpr listed as "partial." It's an ...
