Initializer lists

Description

Example

Uniform initialization

Description

Example

Implicit variables

• Pass & return implicit variables with uniform initialization
• Works with const ref

Initializer lists vs initialization lists

MyStruct(int x, int y): m_nX(x), m_nY(y) {}; // m_nX and m_nY are part of the initialization list
Mystruct foo {3, 4}; //// foo initialized using an initializer_list

Back to quiz

• Create and use an initializer list constructor
• Pass & return some implicit objects using uniform initialization
