+
+Even though the above code works, a **much** better option is to structure your code such that `goto` is not needed for the program flow. For this reason, many modern programming languages (like java, javascript, python, etc.) do support `goto`. Instead, control statements like `break` and `continue` are used.
+
+The above example can be rewritten using `break` as:
+```C++
+#include <iostream>
+using std::cout;
+
+int main(){
+    for(;;){
+        if(1) break;
+    }
+    
+    cout << "lol";
+    
+    return 0;
+}
+```

+
+**However, care must be taken to use goto very carefully**, especially in the early days of coding as it can lead to crazy issues, if not understood well enough. `goto` violates the standard flow of the program, and as C++ is an object oriented language, goto should **NEVER EVER, EVER** be used in a normal program, under **ANY CIRCUMSTANCES**. The same effect can usually be replicated by using functions or loops, with the resulting code being easier to read as well as maintain.
