How do you split a string into tokens in C++?
862
In C, the strtok() function is used to split a string into a series of tokens based on a particular delimiter. A token is a substring extracted from the original string.
split() The method split() splits a String into multiple Strings given the delimiter that separates them. The returned object is an array which contains the split Strings. We can also pass a limit to the number of elements in the returned array.
The first time the strtok() function is called, it returns a pointer to the first token in string1. In later calls with the same token string, the strtok() function returns a pointer to the next token in the string. A NULL pointer is returned when there are no more tokens. All tokens are null-ended.
In computer programming, a delimiter is a character that identifies the beginning or the end of a character string (a contiguous sequence of characters).
this works nicely for me :), it puts the results in elems. delim can be any char.
std::vector<std::string> &split(const std::string &s, char delim, std::vector<std::string> &elems) {
std::stringstream ss(s);
std::string item;
while(std::getline(ss, item, delim)) {
elems.push_back(item);
}
return elems;
}
