CCS/EK-TM4C123GXL: EK-TM4C123GXL-UART

Part Number:EK-TM4C123GXL

Tool/software: Code Composer Studio

Hello i am trying to use following code to update my variables from pc using UART,  but using UARTgetc() i get only single character (i.e if i send 13 i will only receive 3), is there anyway i can get the full number.

Other issue is that i am receiving character but i need integers.
