【max num】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 【my answer】

#include<stdio.h> int main() {     int t, n, i;     double a[100], max;     scanf("%d",&t);     getchar();     while(t--)     {         scanf("%d",&n);         for(i=0;i<n;i++)         {             scanf("%lf",&a[i]);         }         max=a[0];         for(i=1;i<n;i++)         {             if(a[i]>max)             {                 max=a[i];             }         }         printf("%.2lf\n",max);     }     return 0; }
