Back To C++ Pointers

a pointer can be used to store the address of a variable, for example an integer pointer can store address of a integer variable. a float pointer can store address of a float variable
value of a variable can be retrieved through pointer to that variable using dereference operator(*)

//program to create a float pointer to float variable #include<iostream.h> #include<conio.h> void main() { float a; float *ptr; clrscr(); cout<<"\nenter a value for a "; cin>>a; ptr=&a; cout<<"\naddress of variable a is "<<ptr; cout<<"\nvalue of a can also be retrieved through pointer, value of a is "<<*ptr; getch(); }
