Write a program in C++ to add two numbers using pointers

Algorithm to add two numbers using pointer

Firstly, Initialize two variables of integer type.
Secondly, Initialize two pointers of integer type.
Thirdly, Reference the pointers to variables with the help of ‘&’ operator.
With the help of * operator, access the address pointed by pointers.
Sum the values of variables, and store it on another variable.
Display the sum after calculations.

C++ Program to add two numbers using pointers

Write a program in C++ to add two numbers using pointers.

#include <iostream>
using namespace std;
int  main()
{
   int  FirstNumber, SecondNumber;
   int  *FirstPointer,* SecondPointer;
   int  sum;
   cout<<"\n Enter the first number: ";
   cin>>FirstNumber;
   cout<<"\n Enter the second number: ";
   cin>>SecondNumber;
   FirstPointer = &FirstNumber; //assigning an address to pointer
   SecondPointer = &SecondNumber; 
   sum = *FirstPointer + * SecondPointer; //values at address stored by pointer
   cout<<"\n The Sum is: "<< sum;
   return  0;
}

#include <iostream>

using namespace std;

int main()

{

int FirstNumber, SecondNumber;

int *FirstPointer,* SecondPointer;

int sum;

cout<<"\n Enter the first number: ";

cin>>FirstNumber;

cout<<"\n Enter the second number: ";

cin

>>SecondNumber;

FirstPointer = &FirstNumber; //assigning an address to pointer

SecondPointer = &SecondNumber;

sum = *FirstPointer + * SecondPointer; //values at address stored by pointer

cout<<"\n The Sum is: "<< sum;

return 0;

}

Output

Enter the first number:

Enter the second number:

The Sum is: 9
