## Problem statement

Given two integer number and find the subtraction of them using C program.

In this program, we are reading two integer numbers in variable a and b and assigning the subtraction of a and b in the variable sub.

Example 1:

```Input number 1: 40
Input number 2: 45
Output: -5
```

Example 2:

```Input number 1: 45
Input number 2: 40
Output: 5
```

## Program to find subtraction of two numbers in C

```#include<stdio.h>

int main()
{
int a,b,sub;

printf("Enter the first no.: ");
scanf("%d",&a);

printf("Enter the second no.: ");
scanf("%d",&b);

//formula of subtraction
sub= a-b;
printf("subtract is = %d\n", sub);

return 0;
}
```

Output

```First run:
Enter the first no.: 40
Enter the second no.: 45
subtract is = -5

Second run:
Enter the first no.: 45
Enter the second no.: 40
subtract is = 5
```
