You must specify the size of the arry, and you can not use that syntax
to initialise an array of strings.

class obj{
string s[3];
public:
obj(){
s[0] = "bla";
s[1] = "blaaa";
s[2] = "...";
}
};

A C++ array requires a size to be specified for the
number of elements you require.

public:
obj(){
s = {"bla", "blaaa", "..."};

You cannot assign to a C++ array like that. You
may be able to assign a new std::string array to
a std::string* pointer, but I don't reccomend it.

I also do not reccomend what you're attempting to
do in the constructor with const string literals.

An appropriae data structure to use here might be a
std::vector<std::string>, which is initialised in the
constructor initialiser list.

Thank you very much

As other's stated the work around, I'll just mention that perhaps you should
use std::vector instead of a fixed array.

class obj
{
std::vector<std::string> s;
obj()
{
s.push_back("bla");
s.push_back("Blaaa");
s.push_back("...");
}
};
