The video tutorial explains the concept of compile time if in C++, highlighting its syntax and usage with the constexpr keyword. It discusses how compile time if can be used in both template and non-template functions, ensuring only the block with the true condition is evaluated. The tutorial provides examples of implementing a print function that handles different data types, such as pointers and arrays, using compile time if. It emphasizes the importance of having valid code in discarded blocks, even if they are not part of the final executable. The video concludes with a demonstration of how compile time if resolves issues with printing values from various data types.

Describe how compile time if can be utilized with different data types such as pointers and arrays.

How does the evaluation of conditions in compile time if differ from runtime evaluation?

What happens if the statements in the discarded blocks of a compile time if are invalid?
