C语言版

#include <stdio.h>

#define MAXN 10
typedef float ElementType;

ElementType Max(ElementType S[], int N);

int main()
{
   
	ElementType S[MAXN];
	int N, i;

	scanf("%d", &N);
	for (i = 0; i < N; i++)
		scanf("%f", &S[i]);
	printf("%.2f\n", Max(S, N));

	return 0;
}

ElementType Max(ElementType S[], int N) {
   
	ElementType max = S[0];
	for (int i = 1; i < N; i++)
		if (max < S[i])
			max = S[i];
	return max;
}

C++版

#include<iostream>
#include<iomanip>
using namespace std;

#define MAXN 10
typedef float ElementType;

ElementType Max(ElementType S[], int N);

int main() {
   
	ElementType S[MAXN];
	int N;
	cin >> N;
	for (int i = 0; i < N; i++)
		cin >> S[i];
	cout << fixed << setprecision(2) << Max(S, N);
	return 0;
}

ElementType Max(ElementType S[], int N) {
   
	ElementType max = S[0];
	for (int i = 1; i < N; i++)
		if (max < S[i])
			max = S[i];
	return max;
}

Java版

public class Main{
   

	private static final int MAXN = 10;
	
	private static float Max(float []S, int N) {
   
		float max = S[0];
		for (int i = 1; i < N; i++) {
   
			if(max < S[i])
				max = S[i];
		}
		return max;
	}
	
	public static void main(String[] args) {
   
		int N =0;
		float [] S = new float[MAXN];
		Scanner scanner = new Scanner(System.in);
		if (scanner.hasNext()) {
   
			N = scanner.nextInt();
			for (int i = 0; i < N; i++) {
   
				S[i] = scanner.nextFloat();
			}
		}
		scanner.close();
		DecimalFormat decimalFormat = new DecimalFormat("#.00");
		System.out.println(decimalFormat.format(Max(S, N)));
	}

}
