yes desktop c++ is totally different from code that will run on 8052. My approach to coding a complex C algorithim is to test it using TC. that is why i tested all dates to seconds conversion algorithim in TC because it is very easy to debug in TC on desktop than testing on 8051 where i do not have monitor but only few LED's.

But you an see that the function i am trying to run on 8051 has been compiled correctly on KEIL C and it run correctly in the debugger. its only when i burn it on 8052 and try to verify the results.

so should i modify the question as

"Is it possible that some code is compiled with Keil C and results are also verified in Keil Debugger, but it does not run when the code is burn in 8052."


i am really having bad experience when it comes to complex maths programming on 8052. as can be seen its only operations like y % 400 in the function which is creating problems


Is this possible that i convert all mathmatical operations divisions or getting reminder using only addition and subtractions operations because i am much more comfortable working with only additions and subtractions on 8052
