distruibuted program... okay so sim having trouble with my:

Both programs are suppose attach to the same shared memory segment.

The consumer reads the message, modifies it $($e$.$g$.,$ converts it to uppercase$),$ and then writes the modified message back into the shared memory. please attach photo of the teminals showing the output:
