c# 实现 加减乘除

namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
Console.Write("输入第一个数字:");
string a = Console.ReadLine();
char c = char.Parse(a);

Console.Write("输入第二个数字:");
string b = Console.ReadLine();
char d = char.Parse(b);
Console.Write(Environment.NewLine);

int addNum = c + d;
int subNum = c - d;
int purNum = c * d;
int divNum = c / d;

Console.WriteLine("两大数相加结果为：{0}", addNum);
Console.WriteLine("两大数相减结果为：{0}", subNum);
Console.WriteLine("两大数相乘结果为：{0}", purNum);
Console.WriteLine("两大数相除结果为：{0}", divNum);

Console.ReadLine();
