decimal

Program in C

### Here is the source code of the C Program to convert binary to a decimal using a while loop.

Code:

#include <stdio.h>
#include <math.h>
int
main ()
{
int binary;
printf("Enter Binary number:");
scanf("%d", &binary);
int decimal= 0, temp = 0, reminder;
while (binary!=0)
{
reminder = binary % 10;
binary = binary / 10;
decimal = decimal + reminder*pow(2,temp);
temp++;
}

printf("Decimal number is: %d",decimal);
return 0;
}

Input/Output:
Enter Binary number:
1011110
Decimal number is: 94

Program in C++

### Here is the source code of the C++ Program to convert binary to a decimal using a while loop.

Code:

#include <iostream>
#include<cmath>
using namespace std;
int
main ()
{
int binary;
cout<<"Enter Binary number:";
cin>>binary;
int decimal= 0, temp = 0, reminder;
while (binary!=0)
{
reminder = binary % 10;
binary = binary / 10;
decimal = decimal + reminder*pow(2,temp);
temp++;
}

cout<<"Decimal number is: "<<decimal;
return 0;
}

Program in Java

### Here is the source code of the Java Program to convert binary to a decimal using a while loop.

Code:

import java.util.Scanner;
public class BinaryToDecimal {

public static void main(String[] args) {
Scanner cs=new Scanner(System.in);
int binary;
System.out.println("Enter Binary number:");
binary=cs.nextInt();
int decimal= 0, temp = 0, reminder;
while (binary!=0)
{
reminder = binary % 10;
binary = binary / 10;
decimal = (int) (decimal + (reminder*Math.pow(2,temp)));
temp++;
}
System.out.println("Decimal number is: "+decimal);
cs.close();
}
}

Input/Output:
Enter Binary number:
110110
Decimal number is: 54

Program in Python

### Here is the source code of the Python Program to convert binary to a decimal using a while loop.

Code:

print("Enter Binary number:")
binary=int(input())
decimal= 0
temp = 0
while (binary!=0):

reminder = binary % 10
binary = binary // 10
decimal = decimal + reminder*pow(2,temp)
temp=temp+1
print("Decimal number is: ",decimal)

Input/Output:
Enter a Decimal Number:
5
The Binary Number is:  101
