}

为什么我按了一下 1 再按下回车键``就闪了``
再按ALT+F5什么都没有```

#include<stdio.h>
#include<conio.h>

void oftoc(void);

int main()
{
char xh;
clrscr();
printf("Please choses:");
scanf("%d",&xh);
switch(xh)
{
case 1:oftoc();
break;
default:
break;
}
return 0;
}

void oftoc(void)
{
float celsius;
printf("Input celsius:");
scanf("%f",&celsius);
printf("The fhar is:%.3f\n",5.0 * (celsius-32.0) /9.0 );
}

case '1': oftoc(); break ; 你这样是输如1的ASII
改为 case 1: oftoc(); break ; 就行拉
