Printing Size of Different Data Types

In this C# program – we are going to print size of various data types, to print size of a type, we use sizeof() operator.

It accepts a data type and returns its size in the memory.

C# code to print size of different data types

// C# program to C# program to print 
// size of various data types

using System;
using System.IO;
using System.Text;

namespace IncludeHelp {
  class Test {
    // Main Method 
    static void Main(string[] args) {
      Console.WriteLine("sizeof(int): {0}", sizeof(int));
      Console.WriteLine("sizeof(float): {0}", sizeof(float));
      Console.WriteLine("sizeof(char): {0}", sizeof(char));
      Console.WriteLine("sizeof(double): {0}", sizeof(double));
      Console.WriteLine("sizeof(bool): {0}", sizeof(bool));

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

Output

sizeof(int): 4
sizeof(float): 4
sizeof(char): 2
sizeof(double): 8
sizeof(bool): 1
