从.txt文件(fstream、c++)中排序整型变量

#include <fstream>
#include <iostream>

int main() {
    std::ifstream inputFile("file.txt");
    if (!inputFile) {
        std::cout << "Failed to open the file." << std::endl;
        return 1;
    }

    // 接下来的步骤...
    
    inputFile.close(); // 关闭文件
    return 0;
}

#include <vector>

std::vector<int> numbers; // 存储整型变量的容器

    numbers.push_back(number);
}

#include <algorithm>

std::sort(numbers.begin(), numbers.end());

std::ofstream outputFile("sorted_file.txt");

    return 1;
}

for (int num : numbers) {
    outputFile << num << std::endl;
}

outputFile.close(); // 关闭文件
