////加减乘除求余两边的操作数都是整数的话，结果还是整数，不过不能被整除的话，自动略去小数部分
//Console.WriteLine("加法的结果:{0} \n 减法的结果：{1} \n乘法的结果:{2}\n除法的结果:{3}\n求余运算的结果:{4}",res1,res2,res3,res4,res5);
//Console.WriteLine(res);
//关于加法运算符更多的使用
//1.字符串相加 用来连接两个字符串 返回一个字符串
//string str1 = "123adb";
//string str2 = "泰课在线www.taikr.com";
//string str = str1 + str2;
//Console.WriteLine(str);
//2,当一个字符串跟一个数字相加的话，首先把数字转变成字符串，然后连接起来 结果是字符串
//string str1 = "123";
//int num = 456;
//string res = str1 + num;
//Console.WriteLine(res);
