Don't use `const char*`. Cut suggests removal, which `const` doesn't really allow. – erip Mar 23 '16 at 17:31

I need to use const char* because a sdl function need that.. – SMB Punt Mar 23 '16 at 17:32

Use `std::string` until you need the parameter, then create a `const char*` from the `std::string`. – erip Mar 23 '16 at 17:32

Be sure not to use a shallow copy of the object. – erip Mar 23 '16 at 17:37

I think what you are looking for is the std::strtok() function. There is a reference here.
You will need to copy your original data into a temporary area that does not have the const attribute. std::strtok() will split your string up according to the delimiter you specify, in this case a single blank character.
Each successive call to std::strtok() will advance a pointer to the next token in the string.

You can't use stroke on a constant string. It modifies the original. – Edward Strange Mar 23 '16 at 17:45

2@CrazyEddie That's why my answer included the sentence "You will need to copy your original data into a temporary area that does not have the 'const' attribute." – Logicrat Mar 23 '16 at 18:15
