code i correct why am i getting '++' needs l-value

12 Sep 2012 by __John_

the expression "sum + *((word16 *) addr)" is not an lvalue i.e. you cannot assign to it. I think you will need to do the increment as a seperate statement.

code i correct why am i getting '++' needs l-value

12 Sep 2012 by __John_

That will depend on what value you want to increment.If you want to increment the word16 that addr is pointing to, then ...(*((word16 *) addr))++;... should do it.Having sead that, I am not sure what you are trying to do, casting addr to a word16 pointer looks a bit wrong.

code i correct why am i getting '++' needs l-value

12 Sep 2012 by __John_

Having looked at your code a bit more I can say that you should not modify the data that addr is pointing to because it is constant data.char data[6]="CM00";data points to constant.const char data[6]="CM00";Would be correct.
