Example 1: C++ Program to convert binary number to decimal
#include <iostream>
#include <cmath>
using namespace std;
int convertBinaryToDecimal(long long);
int main()
{
long long n;
cout << "Enter a binary number: ";
cin >> n;
cout << n << " in binary = " << convertBinaryToDecimal(n) << "in decimal";
return 0;
}
int convertBinaryToDecimal(long long n)
{
int decimalNumber = 0, i = 0, remainder;
while (n!=0)
{
remainder = n%10;
n /= 10;
decimalNumber += remainder*pow(2,i);
++i;
}
return decimalNumber;
}
Output
Enter a binary number: 1111
1111 in binary = 15
