C# int keyword

In C#, int is a keyword which is used to declare a variable that can store an integral type of value (signed integer) the range of -2,147,483,648 to 2,147,483,647. int keyword is an alias of System.Int32.

It occupies 4 bytes (32 bits) space in the memory.

Syntax:

    int variable_name = value;

C# code to demonstrate example of int keyword

Here, we are declaring an int variable num, initializing it with the value 12345 and printing its value, type, and size of an int type variable.

using System;
using System.Text;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            //variable declaration
            int num = 12345;

            //printing value
            Console.WriteLine("num: " + num);
            //printing type of variable
            Console.WriteLine("Type of num: " + num.GetType());
            //printing size
            Console.WriteLine("Size of a int variable: " + sizeof(int));
            //printing minimum & maximum value of int
            Console.WriteLine("Min value of int: " + int.MinValue);
            Console.WriteLine("Max value of int: " + int.MaxValue);

            //hit ENTER to exit
            Console.ReadLine();
        }
    }
}

Output

num: 12345
Type of num: System.Int32
Size of a int variable: 4
Min value of int: -2147483648
Max value of int: 2147483647
