Function Documentation

cat() [1/6]

std::string gul17::cat ( )

inline

Efficiently concatenate an arbitrary number of strings and numbers.

Numbers are converted to strings in the same way as done by std::to_string. cat() reserves the correct amount of space before concatenating the strings and can therefore save several memory allocations compared to concatenation with "+".

std::string str = gul17::cat(13.5, std::string(" quick "), "brown foxes ", "jump over ",
                           42, " lazy dogs'", std::string(" heads."));
// str == "13.500000 quick brown foxes jump over 42 lazy dogs' heads."

Returns

a string containing the concatenation of all arguments.
