Program to convert Binary to Decimal Number
In this example, We will learn how to convert binary number to decimal number.
To understand this example, You must have knowledge in following topics
#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;
}The output of above program is
Enter a binary number: 110
110 in binary = 6 in decimalIn the above example, We have created one function convertBinaryToDecimal() which converts the binary number to the decimal number.
