从键盘输入8个浮点数，编程求出其和、平均值、最大值以及最小值，用函数，在线等~

#include
double sum( double b[],int n);
double average(int n);
double max( double b[],int n);//函数声明与定义要一致
double min( double b[],int n);
double s;
void main()
{
double b[8];
cout<<"请输入8个浮点数:";
for(int i=0;i<8;i++)
cin>>b[i];
s=sum(b,8);
//a=average(8);
//ma=max(b,8);
//mi=min(8,b);
cout<<"sum="< cout<<"average="< cout<<"max="< cout<<"min="<}
double sum(double b[],int n)
{
double sum=0;
for(int i=0;i sum=sum+b[i];
return sum;
}
double average(int n)
{
/*a=0;
for(int i=0;i s=s+b[i];
a=s/n;*/
return s/n;
}
double max(double b[],int n)
{
double max=b[0];
for(int i=1;i {
if(max max=b[i];
}
return max;
}
double min(double b[],int n)
{
double min=b[0];
for(int i=1;i {
if(min>b[i])
min=b[i];
}
return min;
}
