As the title says, how can I seperate a string into individual characters in c++? For example, if the string is "cat" how can I separate that into the characters c,a, and t?
Thanks

2what do you want to do with the characters? They are already separate inside the string, you can access them at will. – Kerrek SB Nov 29 '14 at 16:35

By using the operator[]. e.g.
std::string cat{"cat"};
if(cat[0] == 'c')
//stuff

If you're using std::string you can simply use .c_str( ) that will give you an array of the chars.
In c++11 you could also do:
for( auto c : a )
{
cout << c << '\n';
}

If you want to store them in a vector:
string str("cat");
vector<char> chars(str.begin(), str.end());
for (char c : chars)
cout << c << endl;

You don't even need to make a vector. You can just say `for(char& c: str)` – Cory Kramer Nov 29 '14 at 16:38
