#include

void main()

{

double Num1,Num2;

char Operation;

printf("请输入你想运算的两个数");

scanf("%lf%lf",&Num1,Num2);

printf("请输入运算符(+，-，*，/,%):");

switch(Operation)

{

case '+':printf("%lf%c%lf=%lf",Num1,Num2,Operation,Num1+Num2);

case '-':printf("%lf%c%lf=%lf",Num1,Num2,Operation,Num1-Num2);

case '*':printf("%lf%c%lf=%lf",Num1,Num2,Operation,Num1*Num2);

case '/':printf("%lf%c%lf=%lf",Num1,Num2,Operation,Num1/Num2);

case '-':printf("%lf%c%lf=%lf",Num1,Num2,Operation,(int)Num1%(int)Num2);//double 型不能取余

}

}
