直方图问题 [英] Histogram question
问题描述
致学生：
这是新任务。
Ex7垂直直方图
编写一个程序，读取文本并打印一个垂直直方图（条形图），表示文本中每个字母（AZ）的出现位置。字母（A-Z）以外的字符将被忽略。您可以假设文本中没有小写字母。
要测试的文本：
快速布朗的狐狸在懒鬼狗身上蹦蹦跳跳。这是如何测试你的直方图的一个例子
计划。你可以使用这个例子。

I don''t know .How do i start?
推荐答案
首先要有2维存储每个字母表出现的数组。
根据你读取的字符增加值。
最后你需要打印它
Raghu
First have a 2 dimensional array which stores the occurances of every alphabet.
Increment the value depending on the character u read.
Finally you need to print it
Raghu
<强> @gpraghuram
二维数组没有必要，一维数组就足够了。在打印阶段也不需要2d数组。
@gpraghuram
There is no need in two-dimensional array, one-dimensional array is enough. No need in 2d array during print phase as well.
@OP：我改变了你的主题标题。下次请使用正确的标题;文章发言在这个论坛上不太受欢迎。
