expected primary expression

这是一个编程问题，我可以回答。"expected primary expression" 是编译器提示的错误信息，意思是在代码中缺少主要表达式。这可能是由于语法错误、拼写错误或缺少必要的标点符号等原因导致的。需要仔细检查代码并进行修正。

回答: 报错"expected primary expression"通常是由于语法错误导致的。根据引用\[1\]和引用\[2\]的描述，这个错误可能是由于在代码中使用了不正确的语法或符号导致的。在C++中，primary expression是指表达式中的基本元素，如变量、常量、函数调用等。而在你的代码中，可能存在一些语法错误，导致编译器无法识别这些表达式。你可以检查一下代码中是否有拼写错误、缺少分号、括号不匹配等问题。另外，根据引用\[3\]中的代码示例，你可能需要检查一下是否正确使用了指针和引用符号。希望这些信息对你有帮助。

Expected primary expression.

An expected primary expression is an error message that occurs when a programming language compiler encounters a syntax error in the code. It indicates that the compiler was expecting a valid primary expression, such as a variable, constant, or literal value, but instead encountered an unexpected token or symbol. This error can occur in various programming languages, including C++, Java, Python, and JavaScript, and typically requires the programmer to review the code and correct the syntax error in order to resolve the issue.
