FAQs on C++ Programming Tutorials - Member Initializers Video Lecture - Learn to Program with C++: Beginner to Expert - Back-End Programming
| 1. What are member initializers in C++ programming? |  |
Ans. Member initializers in C++ programming are used to initialize the member variables of a class at the time of object creation. They allow us to specify the initial values for the member variables directly in the class declaration, rather than initializing them in the constructor body.
| 2. How are member initializers different from assignment in constructors? | |
Ans. Member initializers are different from assignment in constructors because they directly initialize the member variables using a colon (:) followed by the variable name and its initial value. On the other hand, assignment in constructors initializes the member variables using the assignment operator (=) within the constructor body.
| 3. Can member initializers be used for all types of member variables? | |
Ans. Yes, member initializers can be used for all types of member variables. Whether it is a primitive data type or a user-defined class object, member initializers can be used to provide initial values for the member variables.
| 4. What is the advantage of using member initializers? | |
Ans. The advantage of using member initializers is that they allow us to initialize the member variables directly in the class declaration, which can make the code cleaner and more concise. It also helps in reducing the execution time by avoiding unnecessary default initialization followed by assignment in the constructor body.
| 5. Can member initializers be used with constructors having parameters? | |
Ans. Yes, member initializers can be used with constructors having parameters. In such cases, the member initializers can be placed after the parameter list of the constructor, allowing us to initialize the member variables using the provided parameter values. This helps in providing initial values to the member variables without the need for additional assignment statements in the constructor body.
