Adding Chars to a Stringstream

I am trying to add the numbers only from a char array into a stringstream object. The code is: 

char[50] buffer = '<15>';
stringstream str;
int page;

str << buffer[1]+buffer[2];
str >> page;

Page should now hold the integer value of 15, but instead it holds the value 102. Any idea what is wrong with my code?

Change

str << buffer[1]+buffer[2];

to

str << buffer[1] << buffer[2];

The way your code is written, you add characters '1' and '5', which are equal to 49 and 53 respectively, so you get 102 and output it to the stream.
