在C++中合并两个文件并将数据放在一起

#include <iostream>
#include <fstream>
#include <string>

int main() {
    std::ifstream file1("file1.txt");
    std::ifstream file2("file2.txt");
    std::ofstream outputFile("merged_file.txt");

    if (!file1 || !file2 || !outputFile) {
        std::cerr << "Error opening files!" << std::endl;
        return 1;
    }

    std::string line;
    // Copy content from file1 to outputFile
    while (std::getline(file1, line)) {
        outputFile << line << std::endl;
    }

    // Copy content from file2 to outputFile
    while (std::getline(file2, line)) {
        outputFile << line << std::endl;
    }

    file1.close();
    file2.close();
    outputFile.close();

    std::cout << "Files merged successfully!" << std::endl;
    return 0;
}
