How to use the bind function in C++

How to use the bind function in C++? for this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible way.

The bind function is in the header file functional

The general form of calling bind:

Auto newCallable = bind (callable, arg_list)

NewCallable is a new callable object, and callable is the original callable object. When newCallable is called, callable is called and the arg_list parameter is passed.

Arg_list parameter

The parameter list contains _ n placeholders and other parameters, _ n is the parameter of the new callable object, and the other is the parameter of the original calling object, and the placeholder is defined in the std::placeholders namespace.

Auto g = bind (f _ a _ r _ b _ c _ r _ 1); / / g is a callable object with two parameters.

G (_ 1 recording 2); / / pass two parameters of g to f call execution

Suppose you call g (x ~ ~ y), then f (a ~ b ~ ~ y ~ c ~ x) will be called.

Bind reference parameter

Using ref or cref to bind, cref creates a const reference.
