# include <stdio.h> # define N main(){ int a, b; ,,,,,,,,,,,,,,,,}; //array中输入需要排序的数字 ]; ; a < N; a++){ if(array[a]>max){ max = array[a]; //使用max函数,快速筛选出最大值 } } printf("Max = %d\n",max,b); }

总结:对象调用方法,与在main 里直接输出没什么大的区别,少用方法, 乱搞++++ package com.c2; import java.util.Scanner; public class DD { // 求数组的平均值即 :a[i]/a.length public static void main(String[] args) { Scanner c = new Scanner(System.in); int a[] = new int[4]; DD b = new DD(); // D
package com.c2; import java.util.Random; import java.util.Scanner; //输入10个数,找出最大一个数,并打印出来. public class IO { public static void main(String[] args) { Scanner c = new Scanner(System.in); System.out.println("请输入3个数------"); int b = c.nextInt(); in
import java.util.Arrays; import java.util.Scanner; //输入3个数a,b,c,按大小顺序输出. public class Test34 { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int[] arr = new int[3]; int count = 0; int s = 0; ; while (count <= 2) { Syst
import java.util.Arrays; import java.util.Scanner; //输入三个整数x,y,z,请把这三个数由小到大输出. public class Test { public static void main(String[] args) { Scanner sc = new Scanner(System.in); int[] arr = new int[3]; int count = 0; int s=0; ; while (count <= 2) { Sy
总结:1.谢谢程老师,一个很好的老师,人很普通,但是浑浊的世界里,那一份真实感动到底~~~~很感谢他 2.这里注意两个方面,也是我最大的弱点:循环和数组的length属性.前者运用不灵活,后者自己总是不能理解.很桑心啦~~~~ package com.c2; public class DD { // 求数组的平均值即 :a[i]/a.length public static double getAva(int a[]) { double s = 0; for (int i = 1; i < a.
1. 编写程序,从键盘上获得用户连续输入且用逗号分隔的若干个数字(不必以逗号结尾),计算所有输入数字的和并输出,给出代码提示如下. n = input() nums = ____①____ s = 0 for i in nums: ____②____ print(s)
