# Find Even Odd Program In C

Finding that a given number is even or odd, is a classic C program. We shall learn the use of conditional statement `if-else` in C.

## Algorithm

Algorithm of this program is very easy −

```START
Step 1 → Take integer variable A
Step 2 → Assign value to the variable
Step 3 → Perform A modulo 2 and check result if output is 0
Step 4 → If true print A is even
Step 5 → If false print A is odd
STOP
```

## Flow Diagram

We can draw a flow diagram for this program as given below − ## Pseudocode

```procedure even_odd()

IF (number modulo 2) equals to 0
PRINT number is even
ELSE
PRINT number is odd
END IF

end procedure
```

## Implementation

Implementation of this algorithm is given below −

```#include <stdio.h>

int main() {
int even = 24;
int odd  = 31;

if (even % 2 == 0)
printf("%d is even\n", even);

if (odd % 2 != 0 )
printf("%d is odd\n", odd);

return 0;
}
```

## Output

Output of the program should be −

```24 is even
31 is odd
```
