Can You Re-Assign Reference Variables in C++?🤔
To start with let us define what is meant by Reference Variable. Reference variable is a type of variable which is regarded as an alias name to an existing variable. Declaring a reference variable I have used a code snippet from C++ programming language Here as you can see that I have declared a variable of type integer and named it as val, As soon as the compiler compiles the statement memory is allocated for the variable val in the stack and initialized with the value 10. With the next statement we are creating a reference variable named ref which is referring the variable val. This also means that there is no separate memory allocated for the variable ref whereas it is just another name for the memory location identified by val. Can we Reassign it? The next question which comes to mind is whether it is possible to reassign the reference variable to refer some other variable at run time for example: In the above example I have created two integer variables val1 and val2 having
