C ++ stringstreams跳过一个字符 [英] C++ stringstreams skipping a character

问题描述
我有一个文件，第一行是> FileName.txt。我的目标是读取这一行，并将FileName.txt保存到名为name的变量。所以我有：
I have a file which the first line reads ">FileName.txt". My goal is to read this line, and save "FileName.txt" to a variable called name. So I have:
ifstream file;
/* File opening stuff */
string line, name;
getline(file,line);
stringstream converter(line);
converter >> name;
这会将> FileName.txt保存到变量 code>，但我需要删除'>'字符。我不知道如果我应该这样做之后，或者如果有一个方法可以跳过它完全使用 stringstream 。
This accomplishes saving ">FileName.txt" to the variable name, but I need to remove the '>' character. I am not sure if I should do that after this point, or if there is a way to skip over it entirely using the stringstream.
推荐答案
您可以很容易地跳过流：
You can skip over it with the stream fairly easily:
char ch;
converter >> ch; // skip initial >
converter >> name; // now read the name
