Question 1: Why we use Reference Variables. Give one example.
int x;
int& foo = x;
// foo is now a reference to x so this sets x to 56
foo = 56;
std::cout << x <<std::endl;
}
Answer:
C++ references allow you to create a second name for the a variable that you can use to read or modify the original data stored in that variable.
main() {int x;
int& foo = x;
// foo is now a reference to x so this sets x to 56
foo = 56;
std::cout << x <<std::endl;
}
