[Error] expected ',' or '...' before '<' token

这个错误通常是因为在模板类型参数的声明中没有正确使用模板关键字“template”。在C++中,如果您想要声明一个带有模板参数的类或函数,您应该使用“template”关键字来声明模板参数。例如:
```
template<typename T>
class MyClass {
// ...
};
```
如果您在没有使用“template”关键字的情况下声明了模板类型参数,则会出现上述编译错误。请检查您的代码并确保正确使用了“template”关键字。

expected primary expression before '.'token
This error message typically occurs in programming languages like C++ or Java, and it means that the code contains a syntax error.
The error message "expected primary expression before '.' token" usually indicates that there is a problem with the code syntax, particularly with the use of a dot (.) character. This character is often used to access properties or methods of objects in object-oriented programming.
Possible causes of this error include:
- Missing or incorrect syntax, such as forgetting to declare a variable or function before using it, or using the wrong type of variable or function.
- Incorrect use of the dot (.) operator, such as using it on a non-object or non-class element, or using it with incorrect syntax.
- Incorrect placement of the dot (.) operator, such as using it in a place where it is not allowed or expected.
To fix this error, you can try checking the syntax of the code and ensuring that all variables and functions are properly declared and used. You can also double-check the use of the dot (.) operator and make sure it is used correctly and in the right place.
error: expected identifier before ‘.’ token是什么意思
这个错误通常是因为在代码中使用了不允许的符号或语法错误导致的。具体来说,这个错误信息表示在代码中使用了一个不被认可的符号"."。通常情况下,这个错误出现在对象或结构体成员的访问中,因为在C或C++语言中,成员的访问需要使用"."符号。解决这个错误的方法是检查代码中是否有语法错误或拼写错误,并确保正确使用了成员访问符号。
