It appears you are missing a brace.

The one above matches to the beginning of the function. There is a brace on the line after this but you are still in the function (I believe).

these 0000000000000 i put it just to marque the error for you it dose'nt find in the program
Sep 17 '12 #6
please can you explain in more detail like give me the line number
Sep 17 '12 #7
how i visit the forum

i try with the brace error in run

Did you mean for the close-brace on line 320 (tagged with 0000000000000000) to terminate the ConstructCalorimeter method? If not, then remove it. If so, then you need to declare the name of the next method before the open-brace on line 322.

By the way, if you add text to tag a line like this you may find it better to make the text a comment so that it doesn't alter the program.
