Question

I’m pretty new to C++ and was looking for a good way to pull the data out of this line.

A sample line that I might need to tokenise is

f 11/65/11 16/70/16 17/69/17

I have a tokenisation method that splits strings into a vector as delimited by a string which may be useful

static void Tokenise(const string& str, vector<string>& tokens, const string& delimiters = " ")

The only way I can think of doing it is to tokenise with ” ” as a delimiter, remove the first item from the resulting vector, then tokenise each part by itself. Is there a good way to do this all in one?

Answer 1

I see the question is tagged as C++ but the absolutely easiest way to do this is with scanf

int indices[3][3];
sscanf(buffer, "f %d/%d/%d %d/%d/%d %d/%d/%d", &indices[0][0], &indices[0][1],...);
