用Xcode在c++中写文件，终端运行

#include <iostream>
#include <fstream>

int main() {
    std::ofstream file("example.txt");
    if (file.is_open()) {
        file << "Hello, World!";
        file.close();
        std::cout << "File created and written successfully." << std::endl;
    } else {
        std::cout << "Failed to create file." << std::endl;
    }
    return 0;
}

g++ main.cpp -o output
./output
