使用C++从文本文件中读取整数并将其存储到向量中

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

std::vector<int> numbers;

std::ifstream inputFile("filename.txt");
if (!inputFile.is_open()) {
    std::cout << "无法打开文件" << std::endl;
    return 0;
}

int number;
while (inputFile >> number) {
    numbers.push_back(number);
}

inputFile.close();

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

int main() {
    std::vector<int> numbers;

    std::ifstream inputFile("filename.txt");
    if (!inputFile.is_open()) {
        std::cout << "无法打开文件" << std::endl;
        return 0;
    }

    int number;
    while (inputFile >> number) {
        numbers.push_back(number);
    }

    inputFile.close();

    // 打印向量中的整数
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;

    return 0;
}
