Answer 1

#include <stdio.h>

int main()
{
    int n，i;
    printf("Please enter number n: ");
    scanf("%d", &n);
    
    printf("Odd number between 1 and %d: ", n);
    for (i = 1; i <= n; ++i)
        if (i %2 == 1)
            printf("%d ", i);
    
    return 0;
}

// Output 
Please enter number n: 20                                                                                                                                                          
Odd number between 1 and 20: 1 3 5 7 9 11 13 15 17 19
