Answer 1

#include<stdio.h>
int main()
{
        char *ptr[]={"Even","Odd"};
        int num;
        printf("Enter a number : ");
        scanf("%d",&num);
        printf("%s\n",ptr[num%2]);
        return 0;
}

Answer 2

odd_even[]={"Even", "Odd"};
printf("%s\n",odd_even[given_number % 2]);

We can use ternary operator.
n%2==0?printf("even"):printf("odd");
