$\huge{\red{\mathtt{\underline{Answer:}}}}$

Program :

#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;

}

Explanation :

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

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
