inferring the data type from the initializer (declaration assignment). However, in the case of out arguments, the signature of the call target can be used to support implicitly typed variables even if there is no initializer. Still, inference isn’t always possible and, further...
4. Using Const with Function Arguments In C++, the const keyword can be used with function arguments to indicate that a function does not modify the value of the argument. When a function argument is declared as const, it cannot be changed within the function. This helps to prevent unintenti...
