把开发过程经常用到的一些代码片段做个珍藏，下面的代码段是关于C语言统计终端输入的行数,单词数与字符数的代码，应该对各位有所用。

include <stdio.h>

main() {
int c, nl, nw, nc, state;
state = OUT;
nl = nw = nc = 0;
while ((c = getchar()) != EOF) {
++nc;
if (c == 'n') {
++nl;
}

    if (c == ' ' || c == 'n' || c == 't') {  
        state = OUT;  
    } else if (state == OUT) {  
        state = IN;  
        ++nw;  
    }  
}  
printf("%d %d %d", nl, nw, nc);  

}

输出结果
