The only way of invoking such a constructor is by letting the compiler deduce the template arguments from the constructor arguments.

In this case, you define an auxiliary constructor function (see std::make_pair):

Struct t { template t(); Template a make_a(t t) { return a(t); Struct u { u() : C++ allows constructors to be templated, but there is no syntax for explicitly specializing the constructor. There is no way to explicitly specify the template arguments when calling a constructor template, so they have to be deduced through argument deduction.

Is it possible to create a template function that takes a variable number of arguments, for example, in this vector< t, c > class constructor: For a class t, its first argument must have type t & or t const & or t volatile & or. C++17 adds support for template argument deduction for constructors of class templates. At the.

C Constructor

A constructor of a class can be a template function. The only way of invoking such a constructor is by letting the compiler deduce the template arguments from the constructor arguments.

A constructor cannot be a. Constructors are considered to deduce the class template parameters, but in some cases this is insufficient and we can provide explicit deduction guides: Another occasion to use a constructor template without a class template is when you need to use the type parameter. } and then use it like this:.</p>
