Write a C program that reads a single integer number from the keyboard via the scanf function, determines if the number is either, positive, zero, or negative and then prints out a message such as: "The number is positive." or "The number is zero." or "The number is negative.

Here is the solution for the above question:

#include <stdio.h>
int main(int argc, char *argv[])
{
    int num;
    
    printf("Please enter a number: ");
    scanf("%d",&num);
    
    if(num == 0)
    {
        printf("The number is zero.\n");
    }
    else if(num > 0)
    {
        printf("The number is positive.\n");
    }
    else if(num < 0)
    {
        printf("The number is negative.\n");
    }	
    return 0;
}
