The volatile keyword is a type qualifier used to declare that an object can be modified in the program by something such as the operating system, the hardware, or a concurrently executing thread. volatile declarator ; Was this answer useful? Yes ReplyRelated...
it can be modified even in a const function.” (在上面的代码中,我们在const成员函数myFunc中修改了成员变量myVar。由于myVar被声明为mutable,所以即使在const函数中也可以修改它。)
C mutable keyword - Mutable data members are those members whose values can be changed in runtime even if the object is of constant type. It is just the opposite of a constant. Sometimes logic requires to use of only one or two data members as a variable

So in C#, we have StringBuilder which is a mutable type. We have some advantages of immutable classes like immutable objects are simpler to construct, test, and use. immutable objects are always thread-safe and etc. StringBuilder StringBuilder is a mutable type, that means we are using the ...
1) 在for in 循环中删除数组内部对象。 NSMutableArray *arr = [[NSMutableArray alloc]initWithObjects:@"1",@"2",@"3",@"3",@"4",@"3",@"5",@"3",@"6",nil]; for (NSString *str in arr) { if ([str isEqualToString:@"3"]) { NSInteger index = [arr indexOfObject:@"3"];...

find a specific value valid or not in a particular situation. Generally speaking, dynamic checking is python - python函数的参数传递是传值还是传引用? 可更改(mutable)对象与不可更改(immutable)对象 str, tuple,和number是不可更改的对象, list,dict等则是可以修改的对象。 example 结论 mutable 变量,传...
1.mutable in class 四、核心概念对比表 conststaticmutable是我们常用的三大修饰关键字,决定了具体变量的访问权限,以及类成员函数的行为权限。 一、const const是一个标志不可改变的修饰词,"const在谁左边,谁就不可变!" 在程序中我们经常会碰见取值后不想被错误修改的情况,我们也不想仅仅是用来获取变量的函数,取...
