"missing ; before statement" 的意思是在语句之前缺少分号。这通常是因为代码中的某个语句没有以分号结尾,导致解析器无法正确识别代码。需要在相应的语句末尾添加分号来解决这个问题。

'<' token
This error message is typically seen when the compiler encounters a syntax error in the code. In this case, it means that there is an unexpected '<' character in the code, and the compiler doesn't know what to do with it.
The most common cause of this error is a missing semicolon at the end of a statement, which can cause the compiler to interpret the following line of code as a continuation of the previous line. Another common cause is a missing header file, which can cause the compiler to fail to recognize a particular function or data type.
To fix this error, carefully check the syntax of the code and make sure that all statements are properly terminated with semicolons. Also, make sure that all necessary header files are included in the code.
expected expression before 'plant_2'
This error message is typically encountered in programming languages like C, C++, or Java when there is a syntax error in the code, usually involving a missing or misplaced operator or keyword.
Without seeing the specific line of code that triggered this error message, it is difficult to provide a more specific explanation. However, the error message suggests that there may be an issue with the syntax of the code related to the variable or identifier "plant_2".
Here are a few examples of code snippets that could trigger this error message:
Example 1:
```
if (plant_1 > 10)
{
// some code here
}
plant_2 = 5; // missing semicolon at end of previous line
```
In this example, the error message would be triggered because there is no semicolon at the end of the line that contains the if statement. The compiler thinks that the if statement is continuing onto the next line and sees "plant_2" as the start of a new statement, hence the "expected expression before 'plant_2'" error.
Example 2:
```
int plant_1 = 5;
int plant_2 = 10;
if (plant_1 > 10) // missing parentheses
{
// some code here
}
else if plant_2 < 5 // missing parentheses and curly braces
// some code here
```
In this example, there are a few syntax errors that could trigger the "expected expression before 'plant_2'" error. Firstly, the if statement is missing parentheses around the condition. Secondly, the else if statement is missing both parentheses around the condition and curly braces around the code block. These errors can cause the compiler to get confused and trigger the error message.
To fix this error, you will need to carefully review your code and look for any syntax errors or missing pieces of code. Make sure that all statements are properly terminated with semicolons, all conditional statements have the correct syntax and formatting, and all variables and identifiers are properly declared and initialized.
