紧急!!!编写程序：输入一行字符,统计其有多少个单词,单词...

#include<stdio.h>
main()
{char c;
int word=0,speac=0;
printf("请输入一行字符:\n");
while((c=getchar())!='\n')
{if(c>='a'&&c<='z'||c>='A'&&c<='Z')
word=1+speac;
else if(c==' ')
speac++;
}
printf("单词=%d,空格数=%d\n",word,speac);
}

楼主是来转移积分的吧。我看你连什么是单词都没搞清楚。

#include <stdio.h>
#include <ctype.h>

int
countWords(void)
{
char c;
int i, state; // state of 1 in a word, 0 out of a word; i as counter

// get input from stdin, press Ctrl+D to send EOF in *nix, Ctrl+Z in M$ Windows
for (i = 0, state = 0; (c=getchar()) != EOF; state = isspace(c) ? 0 : (!state ? (++i,1) : state)); // increament i at the start of a word
return i;
}

int
main(void)
{
printf("%d\n", countWords());
return 0;
}
