excess elements in char array initializer 的意思是：在char数组初始化时，设置了多余的元素。如：const char ChDay[] = { //这里定义的是一个一维字符数组，并进行初始化，一维数组的元素只能是单个的字符，而下面的数据却是字符串，所以，在编译时会报错误。"","初一","初二","初三","初四"...

Structs support fixed length array fields, including char arrays. Empty structs never fully worked and are no longer supported, they are also no longer supported by flatc. NOTE: char arrays are not currently part of Googles flatc compiler - int8 arrays may be used instead. BREAKING: empty ...
