C语言编程Time Limit Exceeded问题

Posted 2022-03-12 CodeToMing

为什么我的代码会Time Limit Exceeded

#include<stdio.h>
int main()
int a,b;
char c;
float d;
int e;
while(scanf("%d%c%d",&a,&c,&b)!=EOF)
switch( c )
case ’ + ':

e=a+b;
printf("%d\\n",e);
break;

case ’ - ':

e=a-b;
printf("%d\\n",e);
break;

case ’ * ':

e=a * b;
printf("%d\\n",e);
break;

case ’ / ':

d=(float)a/b;
printf("%.2f\\n",d);
break;

default: break;


return 0;
