Let’s review our original code.

Let’s hack!

As we can see the value in the memory address 0x10730 is equal to 2017. Let’s change that value in memory to 1981. Let’s continue and watch the value turn to 1981! Successful hack!

Let’s hack a second way! Re-start the program and set a breakpoint at main+28 and continue to the breakpoint.

Let's continue and we see the value in r1 is 2017. Let’s change the value in r1 to 1981. We continue and see the program successfully hacked to 1981!  

Next week we will dive into Character Variables.
