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
#includeusing 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; }
