My experimental const generic crate aljabar is blocked by this issue and currently has to rely on mem::uninitialized to move out of arrays with const generic params. What is especially annoying about this is that size_of, a const function, is totally valid for arrays with const generic param...
2. Object-oriented C++,包含C with classes的面向对象诉求,如classes(构造函数和析构函数), encapsulation, inheritance, polymorphism(多态), virtual函数(动态绑定)等。 3. Template C++,包含泛型编程(generic programming)部分。 4. STL,template程序库,包含containers, iterators, algorithms, function objects等内容。
5. void SomeFunction() { const int a = 10; ... } 6.private static string astr="abcd"; private const string str = astr+"efg"; 1:不能够换成const。new操作符是须要运行构造函数的,所以无法在编译期间确定 2:能够换成const。我们也看到,Reference类型的常量(除了String)仅仅能是Null。
function foo(pair: readonly [string, string]) { console.log(pair[0]); // okay pair[1] = "hello!"; // error} 1. 2. 3. const 断言 TypeScript 3.4 引入了一个名为 const 断言的文字值结构,它的语法是一个类型断言,用 const 代替类型。
...function fn(a: made_up_type) {} // throw with bad type 我们在函数参数上定义了一个不存在的类型,然后调用我们的函数,所以我们得到了两个错误(一个是定义的错误类型...fn(a: Person) {} 我们定义了一个接口,但是使用了一个名为 nam 的属性,这个属性不在对象上,错...
Both references and pointers can beused to change local variables of one function inside another function. Both of them can also be used to save copying of big objects when passed as arguments to functions or returned from functions, to get efficiency gain....

The second meaning is to use it to qualify a pointer. In this usage it means that the program may not change the value being pointed to by using the pointer. However, it does not mean that that value is immutable, as it may be changed by a different pointer, or by a function call...
