Size of the line parameter

Question

Is there any parameter that will read whole line from the input? I know there is getline(buffer, size_of_the_line) function, but I don't want to limit a size_of_the_line property to just the number I define, but limitless. Is there such a thing at all?

Thanks in advance.

Answer 1

Yes, a free function defined in <string> header:

std::getline

#include <iostream>
#include <string>

int main()
{
    std::string line_of_input;
    std::getline(std::cin, line_of_input); // limited only by the max size of string
}
