Q. Write an algorithm to add two numbers using pointers.

 1. Start
2. Declare three integer variables: `i`, `j`, and `sum`.
3. Declare two integer pointers: `a` and `b`.
4. Prompt the user to enter two integers.
5. Read the two integers from user input into variables `i` and `j`.
6. Assign pointer `a` to the address of `i`.
7. Assign pointer `b` to the address of `j`.
8. Calculate the sum by dereferencing pointers `a` and `b` and adding their values.
- `sum = *a + *b`
9. Display the result of the addition.
10. End
