no%init_local 不初始化局部变量。 如果未指定 -xcheck,则编译器缺省使用 -xcheck=%none。如果指定了没有任何参数的 -xcheck,则编译器缺省使用 -xcheck=%all。 在命令行上 -xcheck 选项不进行累积。编译器按照上次出现的命令设置标志。 B.2.85 -xchip[= c] 指定供优化器使用的目标处理器。 c 必须是以下...

struct S { mutable int &r; }; Previous versions of the compiler accepted this, but now the compiler gives the following error: Output Copy error C2071: 'S::r': illegal storage class To fix the error, remove the redundant mutable keyword. char_16_t and char32_t You can no longe...
Flatcc opts to allow arbitrary length fixed length arrays but limit the entire struct to 2^16-1 bytes. Tables cannot hold larger structs, and the C language does not guarantee support for larger structs. Other implementations might have different limits on maximum array size. Arrays of 0 lengt...
enum boole done; struct string str; union number x; 但是,在C++中,可以说明为: boole done; string str; number x; 5、函数原型 C语言建议编程者为程序中的每一个函数建立原型,而Cpp要求为每一个函数建立原型,以说明函数的名称、参数类型与个数,以及函数返回值的类型。 其主要目的是让C++编译程序进行类型...
