How do I read a file in which each line has a different format. I have a file that looks like this
如何读取每行具有不同格式的文件。我有一个看起来像这样的文件
James 0 14 12
Lucy
Lucas 0 45
Alice 87 23 10 23
etc...
And I have to store the values to use them later. How would I do that.
我必须存储值以便以后使用它们。我该怎么做
If each line had the same format I would use getline(), but can I use it here?
如果每行都使用相同的格式,我会使用getline(),但我可以在这里使用吗?

You can use a stringstream to help separate out your values once you get each line. For example:
获得每一行后,您可以使用字符串流来帮助分离您的值。例如:
std::string line = "James 0 14 12";
std::istringstream ss(line);
std::string piece;
while(ss >> piece)
std::cout << piece << '\n';
will print out:
将打印出来:
James
0
14
12
You could add each piece to whatever data structure you want.
您可以将每个部分添加到您想要的任何数据结构中。
