Let's say I had a string. How would I be able to get the value of the first character of that string?
For example:
string str = "apple";
I want to get the first character of str which would return 97.

4`the first character of str which would return 1` What? – DeiDei Dec 19 '16 at 02:12

Because `char test = 'a'` is 1? – John Dec 19 '16 at 02:13
-
Because `sizeof(test) == 1`, or because _a_ is the first letter of the alphabet? – Tas Dec 19 '16 at 02:14

2Oh wait. `a` actually has an integer value of `97`. My bad. – John Dec 19 '16 at 02:14

I was talking about this `(int)test`. Sorry. – John Dec 19 '16 at 02:15

So you're looking to retrieve the `char` representation of a character in a `std::string`? – Tas Dec 19 '16 at 02:15

@Tas Yes. How would one do that? – John Dec 19 '16 at 02:15

4Well, accessing separate characters in your string can be done with `str[i]` or `str.at(i)` or using iterators (`i` is the position). Cast that to `int` if you want the integer value. – DeiDei Dec 19 '16 at 02:16

It's that simple? Wow. – John Dec 19 '16 at 02:16

Yes, a string is an array of characters, right? You can handle it the way you handle a basic array. – DeiDei Dec 19 '16 at 02:18

All of the above is the long way of saying [you need a **good book**](https://stackoverflow.com/questions/388242/the-definitive-c-book-guide-and-list?s=1|32.8232) on C++. – WhozCraig Dec 19 '16 at 03:20

What you're looking for is the ASCII-Value/Code of the specific character.
string str = "apple";
char c1;
char c2;
c1 = str[0];
c2 = str.at(0);
std::cout << static_cast<int>(c1) << std::endl;
std::cout << static_cast<int>(c2) << std::endl;
