Variables in C# in CSharp

What are variables in C#?

When applications run they need to store temporary data in memory. This is done in things termed as variables. Below is a simple code which declares a variable of type integer. So this variable can only hold numeric values.

// DataType variableName

int num=10; // declares a variable with name “num” and data type integer

So let’s write a simple program which takes input from the end user , stores it in a variable and that data is displayed on the screen.

Below is the amended “program.cs” which does the same.

static void Main(string[] args)
{
       string str = Console.ReadLine().ToString(); // read data from the input keyboard
       Console.WriteLine(str); // display what is entered in the str variable
       Console.Read();// make the application wait
}

Let’s try to understand the above program step by step.

string str = Console.ReadLine().ToString();

Console.WriteLine(str)

Console.Read();
