C++ File to Array: Read Files into Arrays

In C++, you can store files in an array variable by first reading the file contents and then saving them in the array. Here is an example code:

#include <iostream>
#include <fstream>
#include <vector>

int main() {
    std::ifstream file("example.txt");
    std::string line;
    std::vector<std::string> lines;

    if (file.is_open()) {
        while (std::getline(file, line)) {
            lines.push_back(line);
        }

        file.close();

        // 将文件内容存储到数组中
        for (const auto& l : lines) {
            std::cout << l << std::endl;
        }
    } else {
        std::cout << "Unable to open file" << std::endl;
    }

    return 0;
}

The code example above opens a file named “example.txt”, reads its contents, and stores each line in a vector. Finally, it prints out the file content. Feel free to modify the code to suit your needs.
