C# variables

C# is a modern, general-purpose, object-oriented programming language developed by Microsoft and approved by Ecma and ISO.

C# was developed by Anders Hejlsberg and his team during the development of the .Net framework.

C# is designed for the Common Language Infrastructure (CLI). The CLI consists of executable code and a runtime environment that allows the use of a variety of high-level languages ​​on different computer platforms and architectures.

C# variables syntax

A variable is nothing more than the name of a storage area for the program to operate on. In C#, each variable has a specific type, and the type determines the memory size and layout of the variable. Values ​​within the range can be stored in memory, and a range of operations can be performed on the variables.

C# variables example

namespace VariableDefinition{
    class Program
    {
        static void Main(string[] args)
        {
            short a;
            int b ;
            double c;
            /* 实际初始化 */
            a = 10;
            b = 20;
            c = a + b;
            Console.WriteLine("a = {0}, b = {1}, c = {2}", a, b, c);
            Console.ReadLine();
        }
