Binary to Decimal conversion program

 3. Binary to Decimal conversion program using C language:-

The C program converts binary number to decimal number that is equivalent. A decimal number can be attained by multiplying every digit of binary digit with a power of 2 and totaling each multiplication outcome. The power of the integer starts from 0 and counts to n-1 where n is assumed as the overall number of integers in a binary number.

Ex:-  (101100001) 2 =(353)10

                                                

ALGORITHMS:-

Step 1: Start

Step 3: The user is asked to enter a binary number as an input

Step 4: Store the quotient and remainder of the binary number in the variable rem

Step 5: Multiply every digit of the entered binary number beginning from the last with the powers of 2 correspondingly

Step 6: Repeat the above steps with the quotient obtained until the quotient becomes 0

Step 7: The sum of the numbers will give the decimal number as a result, print the decimal value.

Step 8: Stop.

CODE:-

 #include<stdio.h>
int main()
{

    int Binary_no,Decimal_no = 0,rem , num , base=1;

    printf("Enter Binary no in(0's and 1's):");
    scanf("%d",&Binary_no);// take inpue from user 
    num = Binary_no; // num value updated.
    while(num>0)// while loop for condirtion.
    {   
       rem = num % 10;//calculate the remof any num.
       Decimal_no = Decimal_no + rem*base;
        /*Decimal value calculate using decimal value and base value  */
       num= num/10; // new number value update.
       base= base*2;// base value updated.
    }
    printf("The decimal value is %d ", Decimal_no);// print the value.
    return 0;// return zero.
}
