BY  USING CONDITIONAL OPERATOR

#include <stdio.h>
int main() {
    int num,x;
    printf("Enter a number: ");
    scanf("%d", &num);
    
  x=(num<0?printf("negative value"):(num==0?printf("you entered 0"):printf("Positive Number")));
  
}

            printf("You entered 0");
        else
            printf("You entered negative number");
    } else
        printf("You entered positive number");
    return 0;
}
