We can define multiple references in a single type definition. Each identifier that is a reference must be preceded by the & symbol:
Example
#include <iostream> int main() { int a = 10; int &b = a; int &c = a; int &d = a; int &e = d; int &f = e; std::cout<<"Before Incrementing\n"<<a; std::cout<<"\n"<<b; a = 60; std::cout<<"after Incrementing\n"<<a; std::cout<<"\n"<<b; std::cout<<"\n"<<c; std::cout<<"\n"<<d; std::cout<<"\n"<<e; getchar(); return 0; }
Output
Before Incrementing 10 10after Incrementing 60 60 60 60 60
