what does pointers work for in c++ code example
Example: c++ pointers
#include <iostream>
using namespace std;
int main () {
int var = 20; // actual variable declaration.
int *ip; // pointer variable
ip = &var; // store address of var in pointer variable
cout << "Value of var variable: ";
cout << var << endl; //Prints "20"
// print the address stored in ip pointer variable
cout << "Address stored in ip variable: ";
cout << ip << endl; //Prints "b7f8yufs78fds"
// access the value at the address available in pointer
cout << "Value of *ip variable: ";
cout << *ip << endl; //Prints "20"
return 0;
}
