Assuming you're doing object oriented compiled programming (java, c++, etc..) Well they're two kind of data types in programming. There's the primitive ones and the objects. If we declare a primitive type variable (like int, boolean, ...) without giving it a value, It will have a default value (0, false, ...) On the contrary, more complicated data types (objects) will not have a default value but a null value (value = null), and the comoilator warns you about it To correct it, simply give it a value when you declare it.

Please link the code in the postđŸ˜¶ It means that you tried to access a variable and the system couldnt find it For example (Python example) print(m) m = "hello" It will raise an error because m didn't "exist" yet

it means you should initialize the variable before using it eg- int a; // this is declaration a=20; // this is initialization or int a=20;

ThewyShift sorry but you are wrong. Only Instance variable and Static variable gets a default value if not initialized. You need to initialize local variable before using it.
