谢谢大神，不过里面有很多符号我还没有学，我学了之后会回来看您的程序的！

@[mythology](/user/816197) 你不必学，除非你学的就是C++，他的语言跑偏了，这是C++，不是C

```c
#include<stdio.h>
int main()
{
int i,s=0,back=0,mum;
int a[12];
for(i=0;i<=11;i++)
scanf("%d\n",&a[i]);
for(i=0;i<=11;i++)
{
s=s+300;
mum=0;
s-=a[i];
if(s<0)
{
printf("%d",-(i+1));
return 0;
}
mum=s/100;
s=s-mum*100;
back=back+mum*100;
}
s=s+(1.2*back);
printf("%d",s);
return 0;
}
```
就是一些小细节问题，仔细看看就知道了
