杭电2071 Max Num

题目最后要求的是输出一个最大值，边输入数据就可以边选出最大的值，另外使用动态数组比较好控制每一组所要的数组的长度，还有要注意输出的格式！！    

Problem Description

There are some students in a class, Can you help teacher find the highest student .

Input

There are some cases. The first line contains an integer t, indicate the cases; Each case have an integer n ( 1 ≤ n ≤ 100 ) , followed n students’ height.

Output

For each case output the highest height, the height to two decimal plases;

 

Sample Input

2

3 170.00 165.00 180.00

4 165.00 182.00 172.00 160.00

Sample Output

180.00

182.00

代码：

#include<iostream>
#include<iomanip>
using namespace std;
int main()
{
int t,n,i;
double temp;
cin>>t;
for(;t>0;t--)
{
temp=0;
cin>>n;
double *q;
q=new double[n];
for(i=0;i<n;i++)
{
cin>>q[i];
if(temp<q[i])
temp=q[i];
}
cout<<fixed<<setprecision(2)<<temp<<endl;
delete []q;
}
return 0;
}
