C#上手练习

1、打印字符串。
2、调用简略办法，办法里有if句子、Swich句子。
usingKingTest01;usingSystem;namespaceKingTest01
{classProgram1
{staticvoidMain(string[]args)
{
Console.WriteLine(“1234的千分位是”+1234/1000);
Console.WriteLine(“1234的百分位是”+1234/100%10);//12.34Console.WriteLine(“1234的十分位是”+1234/10%10);//123.4Console.WriteLine(“1234的个分位是”+1234%10);
Console.WriteLine(“2的10次方是”+(2<<10));
Program1Test=newProgram1();
Test.year(2020);
Test.calculate(11);
Test.calculate1(10,20);
Program1Write=newProgram1();
Write.Write();
}publicvoidyear(inta)
{if(a%4!=0)
{
Console.WriteLine(a+”不是闰年”);
}else{
Console.WriteLine(a+”是闰年”);
}
}publicvoidcalculate(inta)
{
Console.WriteLine(a+”是”+(a%2==0?”偶数”:”奇数”));
}publicvoidcalculate1(inta,intb)
{
Console.WriteLine(a+”和”+b+”较大的是”+(a>b?a:b));
}publicvoidWrite()
{
Console.WriteLine(“请输入您的得分状况”);inta=int.Parse(Console.ReadLine());//将屏幕输入的字符串转换为int类型switch(a/10)
{case10:
Console.WriteLine(“您的得分是”+a+”;十分优异”);break;case9:
Console.WriteLine(“您的得分是”+a+”;优异”);break;case8:
Console.WriteLine(“您的得分是”+a+”;杰出”);break;case7:
Console.WriteLine(“您的得分是”+a+”;不错”);break;case6:
Console.WriteLine(“您的得分是”+a+”;一般”);break;default:
Console.WriteLine(“您的得分是”+a+”;十分糟糕”);break;
}
}
}
}
