Here, we’ll write a program to print the sum of two numbers using a pointer in C++. A pointer in programming holds the address of a variable.

Logic:

We will first initialize two numbers and two pointers. Then reference the pointers to the numbers. Then, using the ‘*’ operator, we will dereference them and store the sum in a variable.

Algorithm:

Declare two integer pointers, ptr1 and ptr2, and initialize them to NULL.
Assign the address of x and y to ptr1 and ptr2, respectively, using the & operator.
To access the values stored at the addresses pointed by ptr1 and ptr2, use the * operator.
Calculate the sum of the values pointed by ptr1 and ptr2, and store the result in a new variable, sum.
Print the value of sum .

Code:

#include <iostream>\nusing namespace std;\nint main()\n{\n    int num1, num2;\n    int *ptr1, *ptr2;\n    int sum;\n    cout << \"\\n Enter first number: \";\n    cin >> num1;\n    cout << \"\\n Enter second number: \";\n    cin >> num2;\n    ptr1 = &num1; //assigning an address to pointer\n    ptr2 = &num2;\n    sum = *ptr1 + *ptr2; //values at address stored by pointer\n    cout << \"\\n Sum is: \" << sum;\n    return 0;\n}\n

Output:

Enter first number: 3\nEnter second number: 4\nSum is: 7\n
