Beginner problem URI 1066 -> Even, Odd, Positive and Negative

Before seeing the solution make sure that you tried enough. Don’t paste the whole code, just find out the logic. If you stuck in trouble, just inform me on comment.



#include<stdio.h>
int main()
{
    int num, i, oddcnt=0, evcnt=0, poscnt=0, negcnt=0;

    for(i=1; i<=5; i++){
        scanf("%d",&num);

        if(num % 2 == 0)
            evcnt++;
        if(num%2 == 1 || num%2 == -1)
            oddcnt++;
        if(num > 0)
            poscnt++;

        if(num < 0)
            negcnt++;

    }
        printf("%d valor(es) par(es)\n",evcnt);
        printf("%d valor(es) impar(es)\n",oddcnt);
        printf("%d valor(es) positivo(s)\n",poscnt);
        printf("%d valor(es) negativo(s)\n",negcnt);

    return 0;
}
