Expexted identifier before …

Hello, i'm new.

I'm trying something, but it won't work.
Can you help me?

Here is the code:

/*

*/

void setup() {
    
}

void loop() {
    int a = 1;
    goto int(a);
}

1: {
  //some code here
}

We do not use goto in C++. We use functions.

OP code.
What is that supposed to do? That is not valid syntax.

but it won't work.
