如何在C++中将文本文件的特定行读入int类型的数组？

ifstream inputFile("input.txt");

if (!inputFile.is_open()) {
    cout << "Failed to open the file." << endl;
    return 0;
}

vector<int> numbers;

string line;
int lineNumber = 1; // 要读取的行数
while (getline(inputFile, line)) {
    if (lineNumber == lineNumberToRead) {
        istringstream iss(line);
        int number;
        while (iss >> number) {
            numbers.push_back(number);
        }
        break; // 已读取到特定行，退出循环
    }
    lineNumber++;
}

inputFile.close();

int arraySize = numbers.size();
int* intArray = new int[arraySize];
for (int i = 0; i < arraySize; i++) {
    intArray[i] = numbers[i];
}

delete[] intArray;
