Like this

    vector<string> lines;
    string line;
    while ( getline(cin,line) ) {
        lines.push_back(line);
    }

[seeplus]

std::vector<std::string> lines;

for (std::string line; std::getline(std::cin, line); lines.push_back(line));

for (const auto& line : lines)
    std::cout << line << '\n'
