Initializer List C Example

An object of type std initializer list t is a lightweight proxy object that provides access to an array of objects of type const t.

Initializer list c example. Initializer lists are mostly used in specific situations where it is not possible to initialize the values in the constructor body. In addition to letting you pick which constructor of the parent class gets called the initialization list also lets you specify which constructor gets called for the objects that are fields of the class. C uses initializer lists to initialize the data members to their values. 1 when no base class default constructor is present.

Explore all about initializer lists in c with examples in detail. 3 for initializing const data member. A braced init list is used to list initialize an object where the corresponding constructor accepts an std initializer list parameter. 2 when reference type is used.

Std initializer list lives in the initializer list header. Std initializer list t is introduced in c 11 to make initialization uniform in c. For instance if you have a string inside your class. Therefore if we create a constructor that takes a std initializer list parameter we can create objects using the initializer list as an input.

But there was no way no to initialize other containers like vector list and map etc. In inheritance base class constructor is called first order of constructor call followed. When a compiler sees an initializer list it automatically converts it into an object of type std initializer list. A std initializer list object is automatically constructed when.
