References in c++
This is a part of c++ language not in c.
-> References are the nick name or alias’s given to a variable.
//simple code to explain References int main() { int a =10; int &r=a; //printing the values of a and r cout<<a; ---------------------------------10 r++; cout<<r -----------------------------------11 cout<<a; --------------------------------11 }
why does we need a reference or a nickname to a variable.
-> This is very useful feature in c++ for parameter passing.
