This is a C# console app I created in Visual Studio to demonstrate some common data types.
using System;
namespace TypeConversionApplication
{
class StringConversion
{
static void Main(string[] args)
{
int i = 75;
float f = 53.005f;
double d = 2345.7652;
bool b = true;
Console.WriteLine("int: " + i.ToString());
Console.WriteLine("float: " + f.ToString());
Console.WriteLine("double: " + d.ToString());
Console.WriteLine("boolean: " + b.ToString());
Console.ReadKey();
}
}
}
Data Types
int : An integer(eg, 3).
Can be a whole number between -2147483648 and 2147483647
float : A fractional(floating point) number(eg, 3.25907).
Can be a number between roughly 1.5 x 10^45 to 3.4 10^38, in floating point format.
String : A sequence of characters(eg, “Hello User 6555”)
(no specified maximum length)
boolean : A true/false value.
Can only contain either the value true or false.
