C++ 试图从txt文件中读取两条数据并将其输出[C+；+；]

void calcBMI:：getWeight（）{
search.open（“name.txt”）；//打开存储用户详细信息的文本文件
if（search.is_open（））
{
while（getline（search，line）和&（getline（search，line2））{//，程序在文本文件中搜索行
如果（line.find（“当前重量（KG）：”）=string:：npos&&（line2.find（“高度（米）”）！=string:：npos））{//
weight[loop]=line；//将从文本文件读取的字符串分配给名为weight的数组
高度[回路]=第2行；
cout这是一个重写版本：

        bool w = false, h = false;
        while (getline(search, line))
        {
            if (line.find("Current Weight(KG):") != string::npos)
            {
                weight[loop] = line; //Assings the strings read from the text file to the array called weight
                w = true;
            }
            else if (line.find("Height(Metres)") != string::npos)
            {
                height[loop] = line;
                h = true;
            }

            if (w && h)
            {
                cout << index[loop] << ". " << weight[loop] << ", " << height[loop] << endl; //Outputs the index array which loops through the numbers in the array and outputs the weight variable which loops through the strings in the array
                loop++; //Iterates the loop 
                w = false;
                h = false;
            }
        }

bool w=false，h=false；
while（getline（搜索，行））
{
if（line.find（“当前重量（KG）：”）=string:：npos）
{
weight[loop]=line；//将从文本文件读取的字符串分配给名为weight的数组
w=真；
}
else if（line.find（“高度（米）”）！=string:：npos）
{
高度[回路]=直线；
h=真；
}
if（w&h）
{
这能回答你的问题吗？你能告诉我你的文件是什么样子吗？
getline（search，line）和&（getline（search，line2）
搜索两行连续的数据，如果两次搜索都成功，则只进入
的正文。查看输入格式后，有一个观察：“哇！这两条线不是并排的！"你应该和duckie坐下来讨论一下这一点的含义。我已经上传了txt文件，我对代码进行了编辑。我相信它会对你的文件起作用。在这种情况下，
if
是没有用的。没有好的方法从错误对齐的文件中恢复。只要阅读这四行并假设它们是正确的，或者编写一个更智能的scanner以确保对齐。它确实有效，但只输出第一个用户和最后一个跳过中间用户的用户。我重写了它。请立即尝试。
