# How to find Binary Addition and Subtraction in C

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 main()
{
int num1,num2;
int Result;

printf("Please enter the First Number: ");
scanf("%d",&num1);

printf("Please enter the Second Number: ");
scanf("%d",&num2);

printf("The Binary Addition of given Numbers is: %d\n",Result);

return 0;
}
{
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 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;

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
```
