I have a vector of strings "moves"
std::vector<string> moves;and the Chars:
char fromX, toX, fromY, toY;I use:
sscanf(moves[0], "%c%c %c%c", &fromX, &fromY, &toX, &toY);and Compiler says:
error: no matching function for call to 'sscanf(std::string&, const char[10], char*, char*, char*, char*)'What is the problem???
Jump to Postsscanf() is a C function, not c++, and knows nothing about c++ containers like std::string, you have to pass it a character array.
sscanf(xx.c_str(), "%c%c %c%c", &fromX, &fromY, &toX, &toY);
Jump to PostNote that sscanf isn't an ordinary method or built-in function, but a very special construction in Pike.
That link is not talking about C or C++ languages.
Jump to PostIn the code snippet you posted above, what string does xx contain? There is probably another way to do what you want without using sscanf(). Post an example of moves[0]

You are right. :S
Compiler says: has no member named 'c_str'

Was an error. its edited in the first post.
Yes I noticed that you changed the first parameter from xx to moves[0]. So what does moves[0] contain anyway?

contain a string
vector <string> moves;
I know that -- but post an example of the string -- such as "Hello World".
