计算字符，单词，行数-C/C++实例代码

#include stdio.h#include ctype.h// for isspace()#include stdbool.h// for bool, true, false

编程学习网为您整理以下代码实例，主要实现：计算字符，单词，行数，希望可以帮到各位朋友。

#include <stdio.h>
#include <ctype.h>         // for isspace()
#include <stdbool.h>       // for bool, true, false

#define Stop '|'
int main(voID)
{
    char c;                 
    char prev;              // prevIoUs character read
    long charCount = 0L;      
    int lineCount = 0;        
    int wordCount = 0;        
    int partiallineCount = 0; 
    bool inword = false;    // == true if c is in a word

    printf("Enter text to be analyzed (| to terminate):\n");
    prev = '\n';            // used to IDentify complete lines
    while ((c = getchar()) != Stop)
    {
        charCount++;          // count characters
        if (c == '\n')
            lineCount++;      // count lines
        if (!isspace(c) && !inword)
        {
            inword = true;  // starting a new word
            wordCount++;      // count word
        }
        if (isspace(c) && inword)
            inword = false; // reached end of word
        prev = c;           // save character value
    }

    if (prev != '\n')
        partiallineCount = 1;
    printf("characters = %ld, words = %d, lines = %d, ",
           charCount, wordCount, lineCount);
    printf("partial lines = %d\n", partiallineCount);

    return 0;
