c语言实现计算器小程序

计算器功能就是“+”“-”“*”“/”，利用switch语句和自带的计算功能实现就行了

程序代码：

#include

int main()

{

int num1,num2;

char function;

printf("please input num1 function num2 :\n");

scanf("%d%c%d", &num1, &function, &num2);

switch(function)

{

case &＃39;+&＃39; :

printf("%d + %d = %d\n",num1,num2,num1+num2);

break;

case &＃39;-&＃39; :

printf("%d - %d = %d\n",num1,num2,num1-num2);

break;

case &＃39;*&＃39; :

printf("%d * %d = %d\n",num1,num2,num1*num2);

break;

case &＃39;/&＃39; :

printf("%d / %d = %d\n",num1,num2,num1/num2);

break;

default:

   printf("error\n");

}

return 0;

}
