Question

1. Write a C++ Program to display address of elements of an array using both array and pointers

2. Write a C++ Program to insert and display data entered by using pointer notation.

3. Write a C++ Program to access Array Elements Using Pointer

Answer 1

1.

CODE

#include <iostream>

using namespace std;

int main() {

float arr[5];

cout<<"Displaying address using array notation: "<< endl;

for (int i = 0; i < 5; ++i) {

cout << &arr[i] <<endl;

}

cout<<"Displaying address using pointers notation: "<< endl;

for (int i = 0; i < 5; ++i) {

cout << arr + i <<endl;

}

return 0;

}

2)

CODE

#include <iostream>

using namespace std;

int main()

{

int data[5];

cout << "Enter elements: ";

for(int i = 0; i < 5; ++i)

cin >> *(data+i);

cout << "You entered: ";

for(int i = 0; i < 5; ++i)

cout << endl << *(data + i);

return 0;

}

3)

CODE

#include <iostream>
using namespace std;

int main()
{
   int data[5];
   cout << "Enter elements: ";

   for(int i = 0; i < 5; ++i)
      cin >> data[i];

   cout << "You entered: ";
   for(int i = 0; i < 5; ++i)
      cout << endl << *(data + i);

   return 0;
}

Output

Enter elements: 1
2
3
5
4
You entered: 1
2
3
5
4
