The Program in C# Program to Check If Given number is Positive or Negative is given below:

using System;

namespace PositiveNegativeCheck
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello Codeauri Family,enter a number here to know whether the numbe is positive or negarive: ");
            int num = Convert.ToInt32(Console.ReadLine());
            if (num > 0)
            {
                Console.WriteLine("Okay,the number is positive.");
            }
            else if (num < 0)
            {
                Console.WriteLine("Okay,the number is negative.");
            }
            else
            {
                Console.WriteLine("The number is zero.");
            }
            Console.ReadLine();
        }
    }
}

Output:

Hello Codeauri Family,enter a number here to know whether the numbe is positive or negarive:
10
Okay,the number is positive.

Pro-Tips💡

Here are the step by step execution of above program:

1. using System;: This line includes the System namespace, which contains various classes and methods used in the program.
2. namespace PositiveNegativeCheck: A namespace is used to organize and group classes in a logical manner.
3. class Program: A class is a blueprint that defines the properties and methods of an object.
4. static void Main(string[] args): The Main method is the entry point of the program and is executed first when the program runs.
5. Console.WriteLine("Hello Codeauri Family,enter a number here to know whether the numbe is positive or negarive: ");: This line displays a message on the console asking the user to enter a number.
6. int num = Convert.ToInt32(Console.ReadLine());: This line reads a string from the console and converts it to an integer.
7. if (num > 0): This checks if the number is greater than 0. If the condition is true, the code inside the if block is executed.
8. else if (num < 0): This checks if the number is less than 0. If the previous if condition was false, and this condition is true, the code inside the else if block is executed.
9. else: If both the previous conditions are false, the code inside the else block is executed.
10. Console.ReadLine();: This line is used to keep the console open so that the output can be read.
