A C++ function can return a reference in a similar way as it returns a pointer. When a function returns a reference, it returns an implicit pointer to its return value. This way, a function can be used on the left side of an assignment statement. The syntax of return a reference is dataType& functionName(parameters); let's take an example that will return a reference #include <iostream> using namespace std; int number; int& retByRef(){ return number; } int main(){ retByRef() = 2; cout << number; return 0; }
