C++: what is the optimal way to convert a double to a string?

Question

What is the most optimal way to achieve the same as this?

void foo(double floatValue, char* stringResult)
{
    sprintf(stringResult, \"%f\", floatV         


        

Answer 1

I'd say sprintf is pretty much the optimal way. You may prefer snprintf over it, but it doesn't have much to do with performance.
