C语言实现输入字符统计 实现统计字符的的功能 问题提出:
从键盘读入一段文本,统计其中的英文字母、数字、空格和除此之外的其他字符个数。
问题分析:
由于输入字符的个数不确定,需构建条件循环while((c=getchar())!=EOF),其中EOF为符号常量,用于表示文本输入结束,在PC机上通过输入Ctrl+Z组合键来输入此字符。所需数据与算法如下。
-C language input character statistics based on statistical character of function problems:
Reading from the keyboard into a text, statistics on the English letters, numbers, spaces, and in addition to other characters.
Problem analysis:
Because of the number of input characters is not identified, should build condition of circulating while ( ( C = getchar ( ) )! = EOF ), where EOF is a symbolic constant, is used to represent text input end, in the PC machine through the Ctrl+Z input key combination to input the character. Required data and the algorithm is as follows.
