4.Compile the Ex4.c file: ccsc100 -be Ex4.c -o Ex4.eld.

The Big Endian (-be) option is used in this exercise to make it easier to read the data in the simulator memory window. If desired, the Little Endian mode can also be used.

5.Run the GUI simulator: guisc100. In the simulator command window, type reset d m1 to put the simulator in Big Endian mode.

6.Open an assembly window: Windows->Assembly.

7.Load the file: Load Ex4.eld.

8.Set a breakpoint on “main” by typing break _main into the command window.

9.Type go. The code should now be at the start of main.

10.Open a memory window: Windows->Memory and click OK.

11.Type data into the Scroll box (of the memory window) to display the contents of the array data[ ] defined in Ex4.c. Verify that these contents are as expected.
