CCS/TM4C1294NCPDT: Timer ADC interrupt

Part Number: TM4C1294NCPDT

Tool/software: Code Composer Studio

I am using Tiva C TM4C1294 connected launchpad to read ADC data from a sensor. I am sampling the ADC using timer interrupt. My code is shown below. In this program, I want the index of the array read_data to go to 0 once the whole of it is filled and the ADC should continuously fill new data to the array but if(i==99) condition does not execute and read_data array does not continuously get updated instead it remains the same after the first 100 fillings. Please, if someone can let me know where I am going wrong.
