👉 In programming, "undefalcated" refers to a condition where there is no value or object assigned to a variable. This can happen if an assignment statement is not properly placed at the end of the file where variables are declared, leading to undefined behavior. For example: ```c++ int x; x = 10; // Undefined ``` In this case, the compiler will complain that there is no value assigned to variable `x` and it cannot be used in subsequent code.
