What does insertions mean?

Question

C++

Answer 1

In terms of input/output in C++, there are two common operators being used, the insertion and extraction operator. Both these operators are defined with I/O stream and derived streams.

● The insertion operator `<<` inserts something into the output stream object. For example we commonly use std::cout object to output something to the screen

`std::cout << some_variable;`

● The extraction operator `>>` extracts something from the input stream object. For example we commonly use std::cin to get input:

`std::cin >> some_variable;`
