c - 增加数组元素的值

Question

任务:

• 提示用户输入 10 个调查标记
• 根据响应进行分类(良好、优秀等)

问题:- 我的最终结果显示一些奇怪的负数 代码:

int marks[10], sum = 0, range[5];

printf("Enter the survey marks for the 10 questions:\n");
for (int i = 0; i < 10; i++){
    scanf("%d", &marks[i]);
    sum += marks[i];
    if (marks[i] == 0){
        range[0] += 1;
    }
    else if (marks[i] == 1){
        range[1] += 1;
    }
    else if (marks[i] == 2){
        range[2] += 1;
    }
    else if (marks[i] == 3){
        range[3] += 1;
    }
    else{
        range[4] += 1;
    }
}

printf("Response\tfrequency\n");
printf("--------\t---------\n");
printf("0-Very Bad\t%5d\n", range[0]);
printf("1-Bad\t\t%5d\n", range[1]);
printf("2-Good\t\t%5d\n", range[2]);
printf("3-Very Good\t%5d\n", range[3]);
printf("4-Excellent\t%5d\n\n", range[4]);

printf("Total mark = %d\n", sum);

Answer 1

呃，只需将我的范围初始化为 0。

range[5] = { 0 }

之后工作哈哈。
