Description: A member initializer list is used to initialize member variables in a constructor. In C++, this feature allows programmers to initialize class member variables more efficiently and clearly. The initializer list is placed after the constructor’s name and before the body, using a colon followed by a comma-separated list. This is particularly useful for initializing member variables that are constants or references, as these must be initialized at the time of the object’s construction. Additionally, using initializer lists can improve performance by avoiding default initialization followed by assignment. In summary, the member initializer list is a powerful tool in C++ that allows for more controlled and efficient initialization of class attributes, contributing to cleaner and optimized code.
