C语言的,帮我编一下.谢谢了

主要是1、2题哇？？？那我就开工了，直接输入的，没经过编译，自己查一下错。

第一题：

#define MAX 0

#define MIN 1

float fun(float a[],float maxmin[])

{int i;

float average,s=0.;

maxmin[MAX]=maxmin[MIN]=a[0];

for(i=0;iN;i++)

{s+=a[i];

if(a[i]maxmin[MAX])maxmin[MAX]=a[i];

if(a[i]=maxmin[MIN])maxmin[MIN]=a[i];

}

average=s/N;

return average;

}//返回的是平均分，主函数定义一个数组maxmin[2]存放最高分和最低分

第二题：

e.....好像n久前做过一次，找找...

哈哈，拿分拿分！！

求大神用函数根据基本工资对应的扣款标准求扣款合计

D2用公式：

=C2*VLOOKUP(B2,IF({1,0},H$2:H$100,SUBSTITUTE(I$2:I$100,"元/班","")),2,)

数组公式，需要按CTRL+SHIFT+回车，完成公式。
