# C++ Program to Check If the Number is Positive or Negative

In this program, we will learn how to check if the number is positive or negative using C++ Programming language.

This program asks the user to enter a number, then we will use an if-else statement to check whether the number is positive or negative.

So, without further ado, letâ€™s begin this tutorial.

## C++ Program to Check If the Number is Positive or Negative

```// C++ Program to Check If the Number is Positive or Negative
#include <iostream>
using namespace std;

int main(){
int num;

cout << "Enter an integer: ";
cin >> num;

// Checking whether the number is positive or negative
if (num > 0){
cout << num << " is a positive number." << endl;
}
else if (num == 0){
cout << num << " is equal to zero." << endl;
}
else {
cout << num << " is a negative number." << endl;
}
return 0;
}
```

Output 1

``````Enter an integer: 12
12 is a positive number.
``````

Output 2

``````Enter an integer: -6
-6 is a negative number.
``````

Output 3

``````Enter an integer: 0
0 is equal to zero.
``````

## How Does This Program Work ?

```    int num;
```

In this program, we have declared an integer data type variable named num.

```    // Asking for input
cout << "Enter an integer: ";
cin >> num;
```

Now, the user is asked to enter an integer. This number gets stored in the num named variable.

```    // Checking whether the number is positive or negative
if (num > 0){
cout << num << " is a positive number." << endl;
}
else if (num == 0){
cout << num << " is equal to zero." << endl;
}
else {
cout << num << " is a negative number." << endl;
}
```

Now, we check whether the entered number is greater or smaller than zero.

• If num > 0, then the entered number is a positive integer.
• If num = 0, then the entered number is equal to zero.
• Otherwise if num < 0, then the entered number is negative.
