TM4C123GH6PM: TM4C123GH6PM

Part Number:TM4C123GH6PM

Hi, I'm working on DHT11 humidity and temperature sensor. According to the datasheet, I have maintained all the protocols for the sensor to run in stable mode. However, my code does goes through my 4th while loop, that I have used to check if there's high data. The following is the loop that goes infinitely. 

while((GPIO_PORTC_DATA_R & 0x10) == High_Out) // Iterates until data line is high
{}

I have pasted the code below, I know how to retrieve data bit by bit, but I cannot go through this part. Any help wiill be appreciated.
