在计数在C段的句子数量 [英] counting the number of sentences in a paragraph in c

问题描述

由于我的课程的一部分，我一直在使用学习C的Turbo C（不幸）。

我们的老师要求我们做一件code的计数在段落的字，词，句的数量​​（只用printf，则getch（）和while循环..他不希望我们使用任何其他命令尚未）。这里是code我写的：

 的#include＆LT;＆stdio.h中GT;
＃包括LT＆;＆CONIO.H GT;无效的主要（无效）
{
clrscr（）;
诠释计数= 0;
INT字= 0;
INT句子= 0;
焦炭CH;而（（CH =残培（））！='\\ n'）
{
    的printf（％C，CH）;
    而（（CH =的getch（））！='。'）
    {
        的printf（％C，CH）;
        而（（CH =残培（））！=''）
        {
            的printf（％C，CH）;
            算上++;
        }
        的printf（％C，CH）;
        也就是说++;
    }
    句子++;
}的printf（字符数是％D，计数）;
的printf（字样的\\ n此数量％D字）;
的printf（句\\ n此数量％D，句子）;
残培（）;
   }
 

它的工作（计至少字符和文字的数量）。然而，当我编译code和检查它在控制台窗口中，我不能让程序停止运行。它应该只要我输入回车键结束。这是为什么？

解决方案

  INT CH;
INT标志;
而（（CH =残培（））！='\\ r'）{
    ++计数;
    标志= 1;
    而（旗＆安培;及（CH ==''|| CH ==''））{
        ++字; //没有好的例如连续空间，空间在句子的开头
        标志= 0 ;;
    }
    标志= 1;
    而（旗＆安培;＆放大器;'。CH ==）{
        ++句子;
        标志= 0;
    }
    的printf（％C，CH）;
}
的printf（\\ n）;
 

As part of my course, I have to learn C using Turbo C (unfortunately).

Our teacher asked us to make a piece of code that counts the number of characters, words and sentences in a paragraph (only using printf, getch() and a while loop.. he doesn't want us to use any other commands yet). Here is the code I wrote:

#include <stdio.h>
#include <conio.h>

void main(void)  
{  
clrscr();  
int count = 0;  
int words = 0;  
int sentences = 0;  
char ch;

while ((ch = getch()) != '\n')
{
    printf("%c", ch);
    while ((ch = getch()) != '.')
    {
        printf("%c", ch);
        while ((ch = getch()) != ' ')
        {
            printf("%c", ch);
            count++;
        }
        printf("%c", ch);
        words++;
    }
    sentences++;
}

printf("The number of characters are %d", count);
printf("\nThe number of words are %d", words);
printf("\nThe number of sentences are %d", sentences);
getch();
   }

It does work (counts the number of characters and words at least). However when I compile the code and check it out on the console window I can't get the program to stop running. It is supposed to end as soon as I input the enter key. Why is that?

解决方案

int ch;
int flag;
while ((ch = getch()) != '\r'){
    ++count;
    flag = 1;
    while(flag && (ch == ' ' || ch == '.')){
        ++words;//no good E.g Contiguous space, Space at the beginning of the sentence
        flag = 0;;
    }
    flag = 1;
    while(flag && ch == '.'){
        ++sentences;
        flag=0;
    }
    printf("%c", ch);
}
printf("\n");
