#include <stdio.h>
int main()
{
    int number;

    printf("Enter an integer: ");
    scanf("%d", &number);

    // True if the number is perfectly divisible by 2
    if(number % 2 == 0)
        printf("%d is even.", number);
    else
        printf("%d is odd.", number);

    return 0;
}

Program to display a number if user enters negative number

// If user enters positive number, that number won't be displayed

#include <stdio.h>
int main()
{
    int number;

    printf("Enter an integer: ");
    scanf("%d", &number);

    // Test expression is true if number is less than 0
    if (number < 0)
    {
        printf("You entered %d.\n", number);
    }

    printf("The if statement is easy.");

    return 0;
}

Output 1

Enter an integer: -2
You entered -2.
The if statement is easy.

When user enters -2, the test expression (number < 0) becomes true. Hence, You entered -2 is displayed on the screen.

Output 2

Enter an integer: 5
The if statement in C programming is easy.
