Read once before the loop and again at the end of each iteration.

Solution explanation

A sentinel value marks the end of the input; it is not processed itself.

#include <stdio.h>

int main() {
    int x, pos = 0, neg = 0, max = 0, any = 0;
    scanf("%d", &x);
    while (x != 0) {
        if (x > 0) pos++;
        else neg++;
        if (!any || x > max) max = x;
        any = 1;
        scanf("%d", &x);
    }
    printf("positive=%d negative=%d\n", pos, neg);
    if (any) printf("max=%d\n", max);
    else printf("max=none\n");
    return 0;
}
