![]() To use getline to read input from the standard input stream, we can simply call the function with std::cin as the input stream and a string variable as the second parameter. By default, the delimiter is the newline character '\n'. Here input_stream is the input stream from which input will be read, string_variable is the string variable in which the input will be stored, and delimiter is an optional parameter that specifies the character at which the input reading should stop. ![]() The syntax of C++ getline is as follows: std::getline(std::istream& input_stream, std::string& string_variable, char delimiter='\n') For more information, read our affiliate disclosure.

Important disclosure: we're proud affiliates of some tools mentioned in this guide. This can save a significant amount of time and reduce the complexity of the code required to handle input. The getline function simplifies this process by allowing programmers to read input from a stream and store it in a string variable in a single line of code. ![]() Input handling is a critical aspect of programming, as it involves taking input from users or external sources and processing it in a meaningful way. It is a member function of the C++ standard library's string class, and its purpose is to streamline the input handling process in C++ programs. C++ getline is a powerful input handling function that is used to read input from a stream, such as the standard input stream, and store it in a string variable.
