四则运算

#include<stdio.h>
void main()
{
 char c;
 float x,y;
 int result;
 scanf("%c %f %f",&c,&x,&y);
 if(c=='+')
  result=(x+y);
 else if(c=='-')
  result=(x-y);
 else if(c=='/')
  result=(x/y);
 else if(c=='*')
  result=(x*y);
 else
 {
  printf("符号不合法\n");
  return ;
 }
 printf("%d \n",result);

}
