Complete Modern C++ - Uniform Initialization (C++11)

The video tutorial explains the evolution of initialization methods from C98 to C++11, focusing on the concept of uniform initialization. It highlights the advantages of using a single syntax for initializing both scalar and array types, preventing bugs, and avoiding narrowing conversions. The tutorial provides examples of different initialization methods, including value, direct, and copy initialization, and discusses the benefits of uniform initialization, such as forcing initialization and preventing most vexing parse issues.

What is one of the main advantages of uniform initialization introduced in C++11?

• It allows the use of parentheses for all types.

• It provides a single syntax for initializing both scalar and array types.

• It requires the use of the assignment operator for all types.

• It eliminates the need for any initialization.

Which type of initialization involves using the assignment operator to set a value?

• Copy initialization

• Direct initialization

• Aggregate initialization

• Value initialization

What is the term for initializing an array by assigning a string directly to it?

• String initialization

• Copy initialization

• Aggregate initialization

• Direct initialization

What is the default value for primitive types when using value initialization with empty braces?

• 1

• 0

• null

• undefined

What common mistake is avoided by using uniform initialization instead of parentheses?

• Overloading the assignment operator

• Forgetting to include a semicolon

• Creating a function instead of initializing a variable

• Using the wrong data type

Which type of initialization should be avoided with user-defined objects?

• Copy initialization

• Aggregate initialization

• Direct initialization

• Value initialization

What is a narrowing conversion in the context of initialization?

• Assigning a larger integer to a smaller integer

• Assigning a floating point type to an integer

• Assigning a string to a character array

• Assigning a boolean to an integer
