## Introduction

I have used CodeBlocks compiler for debugging purpose. But you can use any C++ programming language compiler as per your availability.

#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; }
