Complete Modern C++ - Changes

The video tutorial covers updates introduced in C++17, focusing on direct and copy list initialization, range-based for loop enhancements, and static assert improvements. It explains how C++17 changes the rules for list initialization, allowing more flexibility with iterators in range-based loops, and making the message parameter in static asserts optional. The tutorial provides examples and highlights the implications of these changes, ensuring a comprehensive understanding of the new features.

What happens when using auto with a direct list initialization containing multiple elements in C-17?

• It deduces the type from the last element.

• It is considered ill-formed.

• It results in an initializer list.

• It deduces the type from the first element.

In C-17, what is a key change regarding the begin and end iterators in a range-based for loop?

• They can be of different types.

• They must support the equal to operator.

• They must be initialized to zero.

• They must be of the same type.

What is required for iterators used in a range-based for loop?

• They must be of the same type.

• They must be initialized to null.

• They must be pointers.

• They must support certain overloaded operators.

What is a feature of static assert introduced in C-11?

• It allows runtime assertions.

• It can only check integer types.

• It requires a message parameter.

• It performs compile-time assertions.

In C-17, what is optional in a static assert?

• The type parameter.

• The message parameter.

• The condition parameter.

• The error code.
