In this article, we are going to learn How to find Binary Addition and Subtraction in C two numbers with examples.

C Program to find bnary addition two numbers

In this example, we are taking two input numbers from the user and defining a function that finds the addition of two binary numbers. We are passing these numbers to this function and return the result.

#include <stdio.h>

int BinaryAddition(int num1,int num2);

int main() 
{
	int num1,num2;
	int Result;
	
	printf("Please enter the First Number: ");
	scanf("%d",&num1);
	
	printf("Please enter the Second Number: ");
	scanf("%d",&num2);
	
	Result = BinaryAddition(num1,num2);
	
	printf("The Binary Addition of given Numbers is: %d\n",Result);
	
	
	return 0;
}
int BinaryAddition(int num1,int num2) 
{
	int c; 
	
	while (num2 != 0) 
	{
		//Calculate carry and perform left shift 
		c = (num1 & num2) << 1;
		
		
		num1 = num1^num2;
		num2 = c;
	}
return num1; 
}

Output

Please enter the First Number: 5
Please enter the Second Number: 5
The Binary Addition of given Numbers is: 10

C Program to find bnary substraction of binary two numbers

In this example, we are taking two input numbers from the user and defining a function that finds the subtraction of two binary numbers. We are passing these numbers to this function and return the result. 

#include <stdio.h>

int BinarySubtraction(int num1,int num2);
int BinaryAddition(int num1,int num2) 
{
	int c; 
	
	while (num2 != 0) 
	{
		//Calculate carry and perform left shift 
		c = (num1 & num2) << 1;
		
		
		num1 = num1^num2;
		num2 = c;
	}
	return num1; 
}

int main() 
{
	int num1,num2;
	int Result;
	
	printf("Please enter the First Number: ");
	scanf("%d",&num1);
	
	printf("Please enter the Second Number: ");
	scanf("%d",&num2);
	
	Result = BinarySubtraction(num1,num2);
	
	printf("The Binary Subtraction of given Numbers is: %d\n",Result);
	
	
	return 0;
}

int BinarySubtraction(int num1,int num2)  
{
	int c;
	
	num2 = BinaryAddition(~num2, 1);
	
	while (num2 != 0) 
	{
		//Calculate carry and perform left shift
		c = (num1 & num2) << 1;
		
		num1 = num1 ^ num2;
		num2 = c;
	}
	return num1;
}

Output

Please enter the First Number: 23
Please enter the Second Number: 7
The Binary Subtraction of given Numbers is: 16
