Mismatch between the format specifiers and count and type of values results in undefined behavior and possibly program crash. There is a sequence point between these evaluations. The c date and time functions are a group of functions in the standard library of the c programming language implementing date and time manipulation operations

[1] they provide support for time acquisition, conversion between date formats, and formatted output to strings.
<format> contains format functions such as std::format() and the definition of classes formatter, range_formatter, etc
<print> contains the print functions, allowing for the printing of formatted strings to any output or file stream. The c++ programming language has support for string handling, mostly implemented in its standard library The language standard specifies several string types, some inherited from c, some designed to make use of the language's features, such as classes and raii Since the initial versions of c++.
The c programming language has a set of functions implementing operations on strings (character strings and byte strings) in its standard library Various operations, such as copying, concatenation, tokenization and searching are supported. Format is a function in common lisp that can produce formatted text using a format string similar to the print format string It provides more functionality than print, allowing the user to output numbers in various formats (including, for instance
Hex, binary, octal, roman numerals, and english), apply certain format specifiers only under certain conditions, iterate over data structures.
Comma operator in the c and c++ programming languages, the comma operator (represented by the token ,) is a binary operator that evaluates its first operand and discards the result, and then evaluates the second operand and returns this value (and type)
