Understanding C++ Const and Mutable Modifiers In C++, the const keyword is used to declare constants or immutable values. It can be applied to variables, pointers, function parameters, member functions, and more. Using const enhances code safety and readability by preventing accidental modifications...
Unlike var, identifiers declared with let are not initialized during the compilation phase. Accessing them before the declaration line triggers a ReferenceError. This behavior eliminates traditional hoisting and introduces the Temporal Dead Zone (TDZ). // Traditional var hoisting console.log(alpha);...
Variables with const When applied to variables, the const qualifier prevents modification after initialization. const int MAX_SIZE = 100; MAX_SIZE = 200; // Compilation error Function Parameters Using const with function parameters ensures the arguemnts remain unmodified within the function scope. v...
