convert a string position to int?

[DecemberStorm]

Hey guys, I'm encountering a problem when trying to convert a specific index of a string (like s1[x]) to an int.

After some searching I found methods such as atoi and stringstream to convert entire strings to an int, however those methods don't seem to work for individual positions.

can anyone please suggest what methods should I use?

string input;
int arr[100];

	stringstream convert(input[x]);
			convert>>arr[x];

input[x] gives you a char. So you want to convert a char to an int.

Do you want the ASCII (or whatever encoding you are using) value? Then all you have to do is
arr[x] = input[x];
or if you want to be explicit
arr[x] = static_cast<int>(input[x]);

If input is storing only digits and you want to convert the digits to int you can just subtract '0' from the ASCII value. That will give you the integer value.
arr[x] = input[x] - '0';

thanks a lot! I got it to work now!
