C Program to print all even and odd number in a given interval using recursion

#include <stdio.h>

void printEven(int, int);

void main()
{
    int start, end;

    printf("Enter the number to start: ");
    scanf("%d", &start);

        printf("%d\t", start);

    printEven(start+1, end);
}

{
    if (start > end)

    if (start % 2 != 0)
        printf("%d\t", start);

}

Output

Output

Enter the number to start: 1
Enter the number to end: 10

Even numbers are-
2       4       6       8       10
Odd numbers are-
1       3       5       7       9
