这题实在简单啊……连普及组难度都不及啊……提高组考语言篇吗?
c++

int ans(int point1,int point2,bool work,bool west,int art)

if(point1>85&&west==true)
re+=1000;
if(point2>80&&work==true)

return re;
}
int main()
{
cin>>n;
char ans_name[25];
int maxmoney=0,allmoney=0,i=n;
while(i--)

其实很简单,记录类型就ac,就是读入有点麻烦
```pascalprogram fds;

chang:longint;
end;

i,j,k,l,v,s,t,o,n,g:longint;
beginreadln(n);
for i:=1 to n do
begin
g:=0;
repeat
g:=g+1;
read(a[i].names[g]);
until a[i].names[g]=' ';
a[i].chang:=g-1;readln(a[i].kaofen,a[i].banfen,a[i].bangb,a[i].bangb,a[i].xibu,a[i].xibu,a[i].runwen);

最简单的选择分支,一个个写就行了
