# Found out Negative or Positive number in C++

In this page we will found out negative or positive number C++But question is,

How do we know whether a number is negative or positive.?

as we know

found out negative or positive number C++But how?

``-3 -2 -1 0 1 2 3``

means, All negative numbers are less than 0 while all positive numbers greater than 0, so here we can make two condition using of Relation Operator in C++ such as,

## for find out negative number

``(number<0)``

## for find out positive number

``(number>0)``

But we know zero is neither negative nor positive. So here we will add another one condition to these conditions.

for zero

``(number==0)``

Now we have three conditions, but we can use any two of these conditions.

Here is the program,

## Found out Negative or Positive number in C++

``````#include<iostream>
using namespace std;

int main()
{
clrscr();
int number;

cout<<"Enter number:";
cin>>number;

cout<<endl;

if(number<0)
cout<<"given number is negative";

else if(number>0)
cout<<"given number is positive";

else
cout<<"given number neither negative nor positive";

return 0;
}``````

OUTPUT

Explanation

In the program, a variable number is declared,

``int number;``

In which user-input will be stored.

The program has been executed twice.

1st execution

suppose user entered value 6 so,

``number = 6``

after value entered, In if-statement condition will be checked. such as,

``(number < 0 )``

means,

``6 < 0``

because here, the condition becoming false , so body of if will be skip and execution will be go the
next statement

After this, condition will also be checked in else-if statement

``(number > 0)``

means,

``6 > 0``

here, the condition is becoming true so else-if body will be printed,

thus program terminate successfully,

2nd execution

here user-entered value -6 so,

``number = -6``

after value entered, In if-statement condition will be checked. such as,

``(number < 0)``

means,

``-6 < 0``

here the condition is becoming true so body of if will be printed,

thus program terminates successfully,

here we can also use condition in else-statement such as

``````else if(number==0)
cout<<"given number neither negative nor positive``````
