以上错误的原因可能是你在类之外声明了一个成员变量或者函数,或者代码中缺失了类的定义或模块的声明。
以下是一个简单的类的示例,可能对你有所帮助:
```java
public class MyClass {
private int myNumber;
public MyClass(int number) {
myNumber = number;
}
public int getNumber() {
return myNumber;
}
}
```
如果你在类外声明了一个成员变量或函数,可以将其移动到类的内部;如果代码中缺失了类的定义或模块的声明,可以添加相应的声明语句。
修改后的代码示例:
```java
public class MyClass {
private int myNumber;
public MyClass(int number) {
myNumber = number;
}
public int getNumber() {
return myNumber;
}
public void myMethod() {
// 方法体
}
}
```
请注意,以上代码只是一个示例,具体的修改方法取决于你的代码实现。

test.c:31:2: error: expected declaration or statement at end of input return 0;
This error message is indicating that there is a problem with the syntax of your code in test.c. The compiler is expecting another statement or declaration to follow the line that contains "return 0;", but it has reached the end of the file without finding anything.
To fix this error, you should check your code to make sure that all of your statements and declarations are properly closed and that there are no missing or extra brackets, parentheses, or semicolons. Also, make sure that you have included any necessary header files and that all functions are properly defined and declared.
A default export must be at the top level of a file or module declaration.ts(1258)
This error message occurs in TypeScript when a default export is not declared at the top level of a file or module. In other words, the default export statement must be the first line of code in the file or module.
For example, if you have a file named "myModule.ts" that contains the following code:
```
function myFunction() {
// code here
}
export default myFunction;
```
You will receive the error message because the `export default` statement is not at the top level of the module. To fix the error, move the `export default` statement to the top of the file or module:
```
export default function myFunction() {
// code here
}
```
This ensures that the default export is declared before anything else in the file or module.
