Even Or Odd Number in C

Those Number is called even number if it is divisible by two,, otherwise odd. 

Example of even numbers: 0,2,4,8,9,10 etc.
Example of odd numbers: 1, 3,5,7,9 etc.

1. C program to check even or odd

#include<stdio.h>

int main()
{

    int number;

    printf("Enter any integer: ");

    scanf("%d",&number);

    if(number % 2 ==0)

         printf("%d is even number.",number);

    else

         printf("%d is odd number.",number);

    return 0;

}

Sample output:
Enter any integer: 5
5 is odd number.

2. How to print odd numbers in c

#include<stdio.h>

int main()

{

    int number;

    int min,max;

  

    printf("Enter the minimum range: ");

    scanf("%d",&min);

    printf("Enter the maximum range: ");

    scanf("%d",&max);

    printf("Odd numbers in given range are: ");

    for(number = min;number <= max; number++)

         if(number % 2 !=0)

             printf("%d ",number);

  

    return 0;

}

Sample output:
Enter the minimum range: 1
Enter the maximum range: 20
Odd numbers in given ranges are: 1 3 5 7 9 11 13 15 17 19

3. Even and odd numbers program In Range

#include<stdio.h>

int main()

{

    int number;

    int min,max;

    printf("Enter the minimum range: ");

    scanf("%d",&min);

    printf("Enter the maximum range: ");

    scanf("%d",&max);

    printf("Odd numbers in given range are: ");

    for(number = min;number <= max; number++)

         if(number % 2 !=0)

             printf("%d ",number);

    printf("\nEven numbers in given range are: ");

    for(number = min;number <= max; number++)

         if(number % 2 ==0)

             printf("%d ",number);

  

    return 0;

}

Sample output:
Enter the minimum range: 1
Enter the maximum range: 20
Odd numbers in given ranges are: 1 3 5 7 9 11 13 15 17 19
Even numbers in given ranges are: 2 4 6 8 10 12 14 16 18 20



4. Sum of odd numbers in c

#include<stdio.h>

int main()

{

    int number;

    int min,max;

    long sum =0;

  

    printf("Enter the minimum range: ");

    scanf("%d",&min);

    printf("Enter the maximum range: ");

    scanf("%d",&max);

    for(number = min;number <= max; number++)

         if(number % 2 !=0)

             sum = sum + number;

    printf("Sum of odd numbers in given range is: %ld",sum);

  

    return 0;

}

Sample output:
Enter the minimum range: 1
Enter the maximum range: 100
Sum of odd numbers in given range is: 2500
