C++ sstream Library


Share

C++ sstream Library

The <sstream> library has classes that let you use a string as a stream (a flow of data). You can write to a string and read from a string, in the same way as you use cout and cin.

String streams are useful when you want to split a string into words, convert between text and numbers, or build a string from many values.

Name Description
stringstream A stream that you can both write to and read from, which keeps its data in a string
istringstream A stream that reads from a string, like cin reads from the keyboard
ostringstream A stream that writes to a string, like cout writes to the screen
str() Returns the content of a string stream as a string, or replaces it with a new string
