String initialization problem explanation

Question

I am just curious about this:

std::string s(10);

It doesn't work. I would like to know the reason why it doesn't make a string with 10 elements. This is probably an easy question but I can't figure it out.

There's no version of class std::string constructor that takes an int. If you want for some reason to create one: std::string s(10, ''); This will create a string object of size 10 empty characters. — Raindrop7

std::string has many constructors.

If You want a string with an explicit length, then a character has to be specified which will be used to fill this string:

std::string s(10, ' ');
