Explanation :
* Take the integer which you want to check as input and store it in a variable number.
* Using if,else statements check whether the integer is greater or lesser than zero.
* If it is greater than or equal to zero, then print the ouput as “it is a positive number”.
* If it is lesser than zero, then print the ouput as “it is a negative number”.
* Exit.
