When compiling and running your program with g++
$ g++ ./src/main.cpp ./src/DHT22.cpp -I./include -lwiringPi -o dht22
$ ./dht22
the output looks like
Temp : 12.00 °C, Humidity : 99.90 %
Temp : 0.00 °C, Humidity : 0.00 %
Temp : 12.00 °C, Humidity : 99.90 %
Temp : 24.00 °C, Humidity : 199.80 %

Note
I've been reformatting the output a bit and changing the loop delay to 5000ms inmain.cpp.
We can see zero values and sporadic doubled temperature values and +100 humidity values.
Why is that?
