What do the square brackets in C mean?
In C and other C-like languages, square brackets are used to provide a clear demarcation point for the beginning and end of a block of code. The compiler reads the open brace as the starting point, the code executes, the closing brace marks the end, and the code goes out of scope.

What are programming brackets?
Braces (also called simply “braces” or “brackets”) are an important part of the C++ programming language. After all, the same braces replace the RETURN statement in a subroutine (function), the ENDIF statement in a conditional, and the NEXT statement in a FOR loop.
Why do we need Make_pair?
make_pair() : This template function allows you to create a pair of values without explicitly typing the types.
What is the difference between the standard pair and the _ pair?
‘std::pair’ is not a function, it is a type. and make_par. What is the difference between pair and make_pair? ‘std::pair’ is a type, ‘std::make_pair’ is a function. [….] values. The library also provides a matching template feature to simplify your build. [….] 7 Returns: even (x, y). [….]
What is the difference between make par and make constructor?
There is no difference between using make_pair and explicitly calling the pair constructor with specified type arguments. std::make_pair is more convenient when types are verbose because a template method has a type inference based on its given parameters. For example,
When do you use brackets when writing?
Not commonly used in formal or informal writing, brackets still appear when writing poetry and music. In any use, they mark repeated or joined lines. Brackets are much more common in other fields like: The main uses of angle brackets occur in other fields. A selection of them includes:
What was the purpose of doing _ pair before c++17?
C++17 makes that syntax possible, and thus make_pair redundant. Before C++17, std::make_pair allowed us to write less verbose code: instead of more verbose:
