### C program for multiplication of two binary numbers

C code for product of two binary numbers

C program for multiplication of two binary numbers

#include
<stdio.h>

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;
}
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;
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

Algorithm:

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
