C program to Check Whether a Number is Positive or Negative or Zero?

A number which is greater than 0 is positive and less than 0 are negative. The concept of positive and negative is very important in number theory and programming also. Calculations rely on this concept only.

Input: 0
Output:0 is zero

Explanation

Using conditional statement check the number with 0 weather it is greater than 0 or smaller than 0.

Example

#include <iostream>
using namespace std;
int main() {
   int n=0;
   if(n>0) {
      printf("%d is positive",n);
   } else if(n<0) {
      printf("%d is negative",n);
   } else {
      printf("%d is zero",n);
   }
   return 0;
}
