编程学习网为您整理以下代码实例,主要实现:计算输入中的行,单词和字符,希望可以帮到各位朋友。
#include <stdio.h>
#define IN 1 /* insIDe a word */
#define OUT 0 /* outsIDe a word */
int main() {
int c = 0, nl = 0, nw = 0, nc = 0, state = OUT;
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\n", nl, nw, nc);
}
