英文:
Finding the lowest and largest number in a nested loop
问题
int smallest = 0;int largest = 0;int num;for (int row = 1; row <= 5; row++) {System.out.println();System.out.println("学生 #" + row + " 的成绩：");num = (int)(Math.random() * 50) + 50;double total = 0;smallest = num;for (int col = 0; col < 10; col++) {num = (int)(Math.random() * 50) + 50;System.out.print(num + ", ");total += num * 1.0;}System.out.println();double average = total / 10;System.out.println("学生的平均成绩为：" + average);if (num > largest) {largest = num;}if (num < smallest) {smallest = num;}}System.out.println("最高分数为：" + largest);System.out.println("最低分数为：" + smallest);
英文:
int smallest = 0;int largest = 0;int num;for (int row=1; row<=5; row++){System.out.println();System.out.println("Grades for student #" + row);num = (int)(Math.random()*50)+50;double total = 0;smallest = num;for (int col = 0; col<10; col++){num = (int)(Math.random()*50)+50;System.out.print(num+ ", ");total += num*1.0;}System.out.println();double average = total/10;System.out.println("Average for student is " +average);if (num > largest) {largest = num;}if (num < smallest) {smallest = num;}}System.out.println("The largest score is:" + largest);System.out.println("The smallest score is : " +smallest);
Trying to figure print out the lowest and largest score for random numbers generated in a loop for 5 students. The code is printing out the wrong number for lowest score.

最小和最大数都被初始化为0。它们应该用第一个值进行初始化。
英文:
The smallest and largest number are initialized with 0. They should be initialized with the first value instead.
答案2
得分: 0
你应该将这部分放在嵌套循环内部。
if (num > largest) {largest = num;}if (num < smallest) {smallest = num;}
否则它们只会比较每行最后一列的 num。
英文:
You should put this part inside the nested loop.
if (num > largest) {largest = num;}if (num < smallest) {smallest = num;}
Otherwise they are only comparing num of the last column of each row.

以下是从循环中查找最大值和最小值的代码片段。您可以根据您的要求进行调整。
int minMax = 0;int smallest = 0;int largest = 0;for (int i = 1; i <= totalNumbers; i++) {System.out.print("数字 " + i + ": ");int inputNumbers = console.nextInt();if (inputNumbers > largest) {largest = inputNumbers;} else if (inputNumbers < smallest) {smallest = inputNumbers;}}System.out.println();System.out.println("最小值 = " + smallest);System.out.println("最大值 = " + largest);
英文:
below is a code snippet of finding the largest and smallest value from a loop.you may adjust it with your requirement.
int minMax = 0;int smallest = 0;int largest = 0;for(int i = 1; i <= totalNumbers; i++){System.out.print("Number " + i + ": ");int inputNumbers = console.nextInt();if(inputNumbers > largest){largest = inputNumbers;} else if (inputNumbers < smallest){smallest = inputNumbers;}}System.out.println();System.out.println("Smallest = " + smallest);System.out.println("Largest = " + largest);
