[Error] expected ';', ',' or ')' before '&' token

There are a few possible causes for this error message. Here are some common scenarios:
1. Missing closing parenthesis: If you have a function call or expression that requires a closing parenthesis, but you forgot to include it, the compiler will think that the rest of the code is part of that expression. For example:
```
if (x == y {
// do something
}
```
In this case, the closing parenthesis after `y` is missing, which causes the error. Adding a `)` at the end of the line will fix it.
2. Typo in variable or function name: If you mistyped a variable or function name, the compiler won't recognize it and will assume that it's a new identifier. For example:
```
int x = 42;
printl(x);
```
Here, `printl` should be `printf`, but the compiler doesn't know that and thinks it's a new identifier. Adding an `f` at the end of the line will fix it.
3. Missing semicolon: If you forgot to end a statement with a semicolon, the compiler will think that the next line is part of the same statement. For example:
```
int x = 42
int y = 10;
```
Here, the first line is missing a semicolon, which causes the error. Adding a `;` at the end of the line will fix it.
To fix this error, carefully check your code for any missing or incorrect syntax. Sometimes, the error message might not point to the exact location of the problem, so you may need to look at the surrounding lines as well.
