multiplication of two binary numbers in c language | CTechnotips


Rule of binary multiplication:

0 * 0 = 0
1 * 0 = 0
0 * 1 = 0
1 * 1 = 1

Q. what is the product of the binary numbers 0110 and 0011?

Answer: 0110 * 0011 = 10010



C code for product of two binary numbers
C program for multiplication of two binary numbers

#include
<stdio.h>


int binaryAddition(int,int);


int main(){


    long int binary1,binary2,multiply=0;

    int digit,factor=1;


    printf("Enter any first binary number: ");

    scanf("%ld",&binary1);

    printf("Enter any second binary number: ");

    scanf("%ld",&binary2);


    while(binary2!=0){

         digit =  binary2 %10;


         if(digit ==1){

                 binary1=binary1*factor;

                 multiply = binaryAddition(binary1,multiply);

         }

         else

             binary1=binary1*factor;

   

         binary2 = binary2/10;

         factor = 10;

    }


    printf("Product of two binary numbers: %ld",multiply);

   

   return 0;

}


int binaryAddition(int binary1,int binary2){


    int i=0,remainder = 0,sum[20];

    int binarySum=0;


    while(binary1!=0||binary2!=0){

         sum[i++] =  (binary1 %10 + binary2 %10 + remainder ) % 2;

         remainder = (binary1 %10 + binary2 %10 + remainder ) / 2;

         binary1 = binary1/10;

         binary2 = binary2/10;

    }


    if(remainder!=0)

         sum[i++] = remainder;

    --i;

    while(i>=0)

         binarySum = binarySum*10 + sum[i--];


    return binarySum;

}


Sample output:

Enter any first binary number: 1101
Enter any second binary number: 11
Product of two binary numbers: 100111
