- Operators - C++ Users
Operators Once introduced to variables and constants, we can begin to operate with them by using operators What follows is a complete list of operators At this point, it is likely not necessary to know all of them, but they are all listed here to also serve as reference Assignment operator (=) The assignment operator assigns a value to a variable
- Input output with files - C++ Users
Input output with files C++ provides the following classes to perform output and input of characters to from files: ofstream: Stream class to write on files ifstream: Stream class to read from files fstream: Stream class to both read and write from to files These classes are derived directly or indirectly from the classes istream and ostream We have already used objects whose types were
- printf - C++ Users
The length sub-specifier modifies the length of the data type This is a chart showing the types used to interpret the corresponding arguments with and without length specifier (if a different type is used, the proper type promotion or conversion is performed, if allowed):

- vector - C++ Users
Vectors are sequence containers representing arrays that can change in size Just like arrays, vectors use contiguous storage locations for their elements, which means that their elements can also be accessed using offsets on regular pointers to its elements, and just as efficiently as in arrays But unlike arrays, their size can change dynamically, with their storage being handled
