Convert Binary Number to Decimal


Write a C++ Program to Convert Binary Number to Decimal. Here’s simple C++ Program to Convert Binary Number to Decimal in C++ Programming Language.


Numbers in C++


Normally, when we work with Numbers, we use primitive data types such as int, short, long, float and double, etc. The number data types, their possible values and number ranges have been explained while discussing C++ Data Types.


Here is source code of the C++ Program to Convert Binary Number to Decimal. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C++ Program to Convert Binary Number to Decimal  */

#include<iostream>
#include<math.h>

using namespace std;

int main()
{
    unsigned long i,n,num=0,d;
    cout<<"Enter any Binary number:";
    cin>>n;
    cout<<"\nThe Decimal conversion of [ "<<n<<" ] is :: ";

    for(i=0;n!=0;++i)
    {
    d=n%10;
    num=(d)*(pow(2,i))+num;
    n=n/10;
    }

    cout<<num<<"\n";
    return 0;
}

OUTPUT : :


/*  C++ Program to Convert Binary to Decimal  */

Enter any Binary number:1111111

The Decimal conversion of [ 1111111 ] is :: 127

Process returned 0

Above is the source code for C++ Program to Convert Binary to Decimal which is successfully compiled and run on Windows System.The Output of the program is shown above .

#include <iostream>
using namespace std;

int main(){

int bnum, bin, b=1, dec=0;

cout << Enter any binary number: ;
cin >> bnum;

cout << \nThe decimal conversion of [ <<bnum<< ] is: ;

while(bnum!=0){
bin=bnum%10;
dec += bin*b;
b=b*2;
bnum/=10;
}

cout << dec << endl;
}
