[Error] expected ';', ',' or ')' before '&' token这个错误是什么意思

Without additional context or code, it is difficult to provide a specific solution. However, the error message typically indicates a syntax error in the code. Check for missing or misplaced punctuation, such as a missing semicolon, comma, or closing parenthesis. Double-check any function or method calls to ensure the correct number of arguments are being passed. It may also be helpful to review any previous lines of code that may have caused the error.
