Accessing individual characters of strings in c++

Question

If I have a string in c++, is there a way for me to access/change certain letters of that string? (Such as the first letter, or fourth letter, etc)

Answer 1

Although you call it a string it is still is a char array.

So you just can use

test[1];

Why didn't you include the string header in the code? Omitting the string header just makes the code to rely on the implementation of the library since some headers has already included inside other headers ( <string> inside <iostream> in this case ) and therefore, shouldn't be count on.

That's A-OK, no problem. But then you see the OP didn't even aware of such identity!
And BTW, not just adding a necessary header doesn't take too much time and effort at the top of the list but also prevents further hiccups in case of executing the code in another compiler. And finally, I think you believe in promoting good programming practices, don't you?! ;)

You can use [] brackets to access individual characters of a string.
For ex:

char c = s[1];

/*Outputs 0*/
