C#学习第四天

今天都是一些基础的东西，希望以后不要忘记，好好努力下去。
1、输出

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace 输出{    class Program    {        static void Main(string[] args)        {            **Console.WriteLine("Welcome ");**        }    }}

输出为：Welcome

2、显示布尔类型的值

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace 显示布尔型变量值{    class Program    {        static void Main(string[] args)        {            bool content = true;            bool noconent = false;            Console.WriteLine("It is that C# Station provides C# programing language content.", content);            Console.WriteLine("The statement above is not {0}.", noconent);        }    }}

输出：It is that C# Station provides C# programing language content.The statement above is not false.

3、一元算子
一元算子指的是：x++，++x; –x,x–……;

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace 一元算子{    class Program    {        static void Main(string[] args)        {            int unary = 5;            int preIncrement;            int preDecrement;            int postIncrement;            int postDecrement;            int positive;            int negative;            sbyte biNot;            bool logNot;            preIncrement = ++unary;            Console.WriteLine("Pre-Increment:{0}", preIncrement);            preDecrement = --unary;            Console.WriteLine("Pre-Decrement:{0}",preDecrement);            postIncrement = unary++;            Console.WriteLine("Post-Increment:{0}", postIncrement);            postDecrement = unary--;            Console.WriteLine("Post-Decrement:{0}", postDecrement);            positive = +preIncrement;            Console.WriteLine("Positive:{0}", positive);            negative = -preIncrement;            Console.WriteLine("Positive:{0}", negative);            biNot = 0;            Console.WriteLine("Positve:{0}", biNot);            logNot = false;            Console.WriteLine("negative:{0}", logNot);        }    }}

输出为：Pre-Increment:6Pre-Decrement:5Post-Increment:5Post-Decrement:6Positive:6Positive:-6Positve:0negative:False

4、二元算子
二元算子：实际数学运算

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace 二元算子{    class Program    {        static void Main(string[] args)        {            int Num1=4, Num2=5, Result;            float floatResult;            Result = Num1 + Num2;            Console.WriteLine("Num1+Num2={0}", Result);            Result = Num1 - Num2;            Console.WriteLine("Num1-Num2={0}", Result);            Result = Num1 * Num2;            Console.WriteLine("Num1*Num2={0}", Result);            floatResult = Num1 / (float)Num2;            Console.WriteLine("Num1/Num2={0}", floatResult);            Result = Num1 % Num2;            Console.WriteLine("Num1%Num2={0}", Result);        }    }}

输出为：Num1+Num2=9Num1-Num2=-1Num1*Num2=20Num1/Num2=0.8Num1%Num2=4

5、数组学习

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Threading.Tasks;namespace 数组算子{    class Program    {        static void Main(string[] args)        {            int[] myInts = { 5, 8, 0 };            //bool[][] myBools = new bool[2][];            //myBools[0] = new bool[2];            //myBools[1] = new bool[1];            double[,] myDoubles = new double[2,2];            string[] myStrings = new string[3];            Console.WriteLine("myInts[0]:{0}\nmyInts[1]:{1}\nmyInts[2]:{2}\n", myInts[0], myInts[1], myInts[2]);            //myBools[0][0] = true;            //myBools[0][1] = false;            //myBools[1][1] = true;            //Console.WriteLine("myBools[0][0]:{0},myBools[0][1]:{1},myBools[1][1]:{2}", myBools[0][0], myBools[0][1], myBools[1][1]);            myDoubles[0,0] = 0.3;            myDoubles[0,1] = 4.98;            myDoubles[1,0]=9.72762;            myDoubles[1,1] = 89.34343462;            Console.WriteLine("myDoubles[0][0]:{0}\nmyDoubles[0][1]:{1}\nmyDoubles[1][0]:{2}\nmyDoubles[1][1]:{3}\n", myDoubles[0,0], myDoubles[0,1], myDoubles[1,0], myDoubles[1,1]);        }    }}

输出为：myInts[0]:5myInts[1]:8myInts[2]:0myDoubles[0][0]:0.3myDoubles[0][1]:4.98myDoubles[1][0]:9.72762myDoubles[1][1]:89.34343462

这些都是基础的东西，为了学习unity脚本！
给自己加油：你可以的，坚持下去！
