Print Even and Odd Numbers in a Range using C

✅ Print Even and Odd Numbers Between Two Numbers in C

#include <stdio.h>

int main() {
    int start, end;

    // Input the range
    printf("Enter the starting number: ");
    scanf("%d", &start);
    printf("Enter the ending number: ");
    scanf("%d", &end);

    // Validate input
    if (start > end) {
        printf("Invalid input! Starting number must be less than or equal to ending number.\n");
        return 1;
    }

    // Print even numbers
    printf("\nEven numbers between %d and %d are:\n", start, end);
    for (int i = start; i <= end; i++) {
        if (i % 2 == 0) {
            printf("%d ", i);
        }
    }

    // Print odd numbers
    printf("\n\nOdd numbers between %d and %d are:\n", start, end);
    for (int i = start; i <= end; i++) {
        if (i % 2 != 0) {
            printf("%d ", i);
        }
    }

    printf("\n");
    return 0;
}
  

📘 Explanation:

✅ This program takes two integers from the user: starting and ending values.
✅ It uses two separate for loops to filter even and odd numbers:
➤ i % 2 == 0 condition is used to check even numbers.
➤ i % 2 != 0 condition is used for odd numbers.
✅ It handles invalid input if the start value is greater than the end value.

🧾 Sample Output:

Enter the starting number: 10
Enter the ending number: 20

Even numbers between 10 and 20 are:
10 12 14 16 18 20

Odd numbers between 10 and 20 are:
11 13 15 17 19
