Write a C++ program to check whether a given number is positive, negative or 0.
Examples :
Number = -44 Output: Negative Number = 0 Output: 0 Number = 50 Output: Positive
C++ implementation :
#include<bits/stdc++.h> using namespace std; void check(int num) { // if number is negative if(num<0) cout<<"Negative number"<<endl; // if number is positive else if(num>0) cout<<"Positive number"<<endl; // if number is niether negative nor positive, i.e., 0 else if(num==0) cout<<"0"<<endl; } //Driver Program int main() { // take input int num; num = 50; check(num); return 0; }
Output :
Positive number
Note that number 0 is neither negative nor positive.
