In this example we will check if a number is positive or negative in C++
Example
We use an if -else statement in this example after taking input from the user
#include <iostream>
using namespace std;
int main()
{
cout << "number is positive or negative\n\n";
int myNumber;
//taking user input
cout << "Enter a non-zero Number: ";
cin >> myNumber;
//display output depending on result
if (myNumber > 0)
{
cout << "\nEntered number is positive";
}
else
{
cout << "\nEntered number is negative";
}
cout << "\n";
return 0;
}
When you run this you will see something like this
number is positive or negative Enter a non-zero Number: 6 Entered number is positive
number is positive or negative Enter a non-zero Number: -2 Entered number is negative
