读取输入行的第一个单词
//自定义函数-readfw读入输入行中的第一个单词#include <stdio.h>
#include <string.h>
void readfw(char *str1,char *str2);
#define LENGTH 80
int main (void)
{
char str2;
char str1;
puts("enter some words within one line");
gets(str1);
readfw(str1,str2);//读取第一个单词并将其保存在str2中
puts("now this is the result of function readfw");
puts(str2);//输出该单词
return 0;
}
void readfw(char *str1,char *str2)
{
int i=0;
while ((('str1'<91)&&('str1'>64))||(('str1'<123)&&('str1'>91)))
{
*(str2+i)=*(str1+i);
i++;
}
}
