读取多个字符串行，c++到多个变量；

#include <iostream>
#include <string>

int main() {
    std::string line1, line2, line3;

    std::cout << "Enter line 1: ";
    std::getline(std::cin, line1);

    std::cout << "Enter line 2: ";
    std::getline(std::cin, line2);

    std::cout << "Enter line 3: ";
    std::getline(std::cin, line3);

    std::cout << "Line 1: " << line1 << std::endl;
    std::cout << "Line 2: " << line2 << std::endl;
    std::cout << "Line 3: " << line3 << std::endl;

    return 0;
}
