Introduction
I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.
Write C++ program to convert binary number to decimal
#include <iostream>
#include <math.h>
using namespace std;
//Function declartion
int convertBinaryToDecimal(long long n);
int main()
{
long long n;
cout<<"Enter a binary number: ";
// Inputting number from user
cin>>n;
//Printing binary number to decimal
cout<<n<<" in binary = "<<convertBinaryToDecimal(n)<<" in decimal";
return 0;
}
//Function to convert binary number to decimal
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;
}
Result
