编写一个函数，输入一行字符，输出最长的单词
#include<stdio.H>
#include<string.H>
main()
{int alphabetic(char);
int longest(char []);
int i;
char line[100];
printf("input one line");
gets(line);
printf("the longest word is:");
for(i=longest(line);alphabetic(line[i]);i++)
printf("%c",line[i]);
}

int alphabetic(char c)
{if((c>='a'&&c<='z')||(c>='A'&&c<='Z'))
return(1);
else
return(0);
}

int longest(char string[])
{int alphabetic(char c);
int i,length=0,len=0,place,inaword=0;
for(i=0;i<=strlen(string);i++)
{if(alpabetic(string[i]))
{inaword=1;
place=i;
len++;}
else
{inaword=0;
if(length<len)
{length=len;
place=i;
len=0;
}
}
}
return(place);
}

return(place);

修改过了，用MinGW可以编译。成功
