C++ Exercises: Add two binary numbers
C++ Basic: Exercise-60 with Solution
Write a program in C++ to add two binary numbers.
Pictorial Presentation:
Sample Solution:
C++ Code :
#include <iostream>
#include <math.h>
using namespace std;
int main()
{
long bn1,bn2;
int i=0, r=0;
int sum[20];
cout << "\n\n Addition of two binary numbers:\n";
cout << "-----------------------------------\n";
cout << " Input the 1st binary number: ";
cin>> bn1;
cout << " Input the 2nd binary number: ";
cin>> bn2;
while (bn1 != 0 || bn2 != 0)
{
sum[i++] = (int)((bn1 % 10 + bn2 % 10 + r) % 2);
r = (int)((bn1 % 10 + bn2 % 10 + r) / 2);
bn1 = bn1 / 10;
bn2 = bn2 / 10;
}
if (r != 0) {
sum[i++] = r;
}
--i;
cout<<" The sum of two binary numbers is: ";
while (i >= 0) {
cout<<(sum[i--]);
}
cout<<("\n");
}
Sample Output:
Addition of two binay numbers: ----------------------------------- Input the 1st binary number: 1010 Input the 2nd binary number: 0011 The sum of two binary numbers is: 1101
