有吗?通过字符串,我的意思是 std::string
well is there? by string i mean std::string
这是我使用的 perl 风格的拆分函数:
Here's a perl-style split function I use:
void split(const string& str, const string& delimiters , vector<string>& tokens)
{
// Skip delimiters at beginning.
string::size_type lastPos = str.find_first_not_of(delimiters, 0);
// Find first "non-delimiter".
string::size_type pos = str.find_first_of(delimiters, lastPos);
while (string::npos != pos || string::npos != lastPos)
{
// Found a token, add it to the vector.
tokens.push_back(str.substr(lastPos, pos - lastPos));
// Skip delimiters. Note the "not_of"
lastPos = str.find_first_not_of(delimiters, pos);
// Find next "non-delimiter"
pos = str.find_first_of(delimiters, lastPos);
}
}
这篇关于在 C++ 中是否有内置的拆分字符串的方法?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
