how to read an empty string in c++?

Question

consider this code snippet in c++ -

string str;
cin>>str;

If I simply press enter at this stage, the pointer moves to next line but keep waiting for the input even if I intentionally want to input an empty string.

My objective is to read a word. And If I press enter, it should be taken as a empty string.

Use std::getline:

std::string str;
std::getline(std::cin, str);
