Reference is the other name given to the same variable. Pointer is new variable created which can contain address of another variable. Try an experiment Code: # include<iostream> using namespace std; int main() { int i = 90; // variable int &j = i; // reference int *P; // pointer P =&i; cout<<endl<< "address of variable :i" <<&i; cout<< endl << "address of reference: j" <<&j; cout<<endl<<"address of pointer : P"<<&P; return 0; } OUTPUT: address of variable i: 0012FEDC address of reference j: 0012FEDC address of pointer p: 0012FEE0 so you see the address of i and reference j is same , address of pointer P is different.
