Common Error Messages

The example below contains two syntax errors: a missing curly brace on line 2 and a missing

semicolon on line 6. Once again, you should try to correct the rst error in the program before

moving on.

The rst error message comes up on line 4, saying “**Error**:Expected->’{‘. Found ‘int’”. When the

word “Expected->” appears in the Errors display screen, it usually indicates that a piece of syntax

is missing. In this case, it expected to nd the missing curly brace immediately after task main(),

but found the reserved word int instead. To correct this error, you should add the opening curly

brace on line 2 and then recompile your code.

After recompiling your code, any remaining errors will be displayed. Missing semicolons also

display an “Expected->” style error message, but notice that the error for the missing semicolon on

line 6 appears on line 7. This is because the compiler ignores whitespace (blank lines, spaces and

tabs), but expected a semicolon before it encountered the wait command. To correct this error, you

should add a semicolon after the forward command.
