大家帮忙看看这两个程序有什么不同～～
大家帮忙看看这两个程序有什么不同～～一个能出结果，一个出不了～～
坏的：
#include <stdio.h>
#define MAXLINE 1000

int getline(char line[], int maxline);
void copy(char to[], char from[]);

main()
{
int len;
int max;
char line[MAXLINE];
char longest[MAXLINE];

max = 0;
while ((len = getline(line, MAXLINE)) > 0)
if (len > max){
max = len;
copy(longest, line);
}
if (max > 0)
printf("%s", longest);
getch();
return 0;
}

int getline(char s[], int lim)
{
int c, i;

for (i = 0; i < lim-1 && (c = getchar()) != EOF && c != '\n'; i++);
s[i] = c;
if (c == '\n'){
s[i] = c;
++i;
}
s[i] = '\0';
return i;
}

void copy(char to[], char from[])
{
int i;

i = 0;
while ((to[i] = from[i]) != '\0')
++i;
}


好的：
#include <stdio.h>

#define MAXLINE 1000

int getline(char line[], int maxline);
void copy(char to[], char from[]);

main()
{
int len, max;
char line[MAXLINE], longest[MAXLINE];

max = 0;
while ((len = getline(line, MAXLINE)) > 0)
if (len > max){
max = len;
copy(longest, line);
}
if (max > 0)
printf("%s", longest);
getch();
return 0;
}

int getline(char s[], int lim)
{
int c, i;

for (i = 0; i < lim - 1 && (c = getchar())!= EOF && c != '\n'; ++i)
s[i] = c;
if (c == '\n'){
s[i] = c;
++i;
}
s[i] = '\0';
return i;
}

void copy (char to[], char from[])
{
int i;
i = 0;
while ((to[i] = from[i]) != '\0')
++i;
}



[解决办法]

C/C++ code

int getline(char s[], int lim) {     int c, i;          for (i = 0; i  < lim-1 && (c = getchar()) != EOF && c !=  '\n '; i++); //多了各分号        s[i] = c;     if (c ==  '\n '){           s[i] = c;           ++i;     }     s[i] =  '\0 ';     return i; }
