The std::getline() functions reads data from an input stream and writes it to a string object. Unlike cin's >> operator, getline() also reads white spaces, which makes it useful for reading strings that contain blanks. For example:
#include <string>
#include <iostream>
int main()
{
std::string name;
cout<<"enter first name and last name: ";
std::getline(std::cin, name);
}
getline() has three parameters, the third of which is a delimiter serving as a string terminator. By default, the delimiter's value is '\n'. You can override this value and define a different delimiter. For example, you can define the sign '\t' (tab) as the delimiter:
std::getline(cin, name, '\t');
