单词计数以及1.12

Posted 2020-10-11 忘忘它吧

统计行数，单词数与字符数

 1 #include <stdio.h>
 2 
 3 #define IN 1
 4 #define OUT 0
 5 
 6 int main()
 7 {
 8     int c, nl, nc, nw, n;
 9     n = nc = nw = 0;
10     nl = OUT;
11     while((c = getchar()) != EOF){
12         n++;                                     //统计字符数
13         if(c == ‘\n‘)
14             nc++;                                //统计行数
15         if(c == ‘ ‘ || c == ‘\n‘ || c == ‘\t‘)
16             nl = OUT;                            //单词外nl记为OUT 0
17         else if(nl == OUT){                      //输入到单词首字母时执行，nl复制IN 1，并统计单词数
18             nl = IN;
19             nw++;
20         }
21     }
22     printf("字符数%d 行数%d 单词数%d", n, nc, nw);
23     return 0;
24 }

1.12 编写一个程序，以每行一个单词的形式打印其输入

#include<stdio.h>

#define OUT 0
#define IN 1

int main(){
    int c, nl;
    nl = OUT;
    while((c = getchar()) != EOF){
        if(c == ‘ ‘ || c == ‘\n‘ || c == ‘\t‘){
                if(nl == IN){
                    putchar(‘\n‘);
                    nl = OUT;
                }
        }
        else if(nl == OUT){
            nl = IN;
            putchar(c);
        }
        else
            putchar(c);
    }
    return 0;
}
