我遇到的问题是使用标准输入从文件中读取多行整数.文件看起来像:
123
423
235
523
..etc
我目前的代码是:
/*
* Read in the initial puzzle configuration.
* Each line is 4 characters long:
* Row as a character '0' .. '9'
* Column as character '0' .. '9'
* Digit as character '0' .. '9'
* Terminating newline.
* Exits with an error message if there are syntactic
* or semantic errors with any configuration line.
*/
void configure(FILE *puzzle_file) {
int row;
int column;
int value;
while((fscanf(puzzle_file, "%i%i%i\n", row, column, …我正在为我的一个类编写一个简单的文件,这是一个简单的链表活动,我需要对链表进行排序.
这是我到目前为止的源代码:
/*
* Simple list manipulation exercise.
* 1. Create a list of integers.
* 2. Print the list.
* 3. Sort the list.
* 4. Print the list
* 5. Free the list nodes.
*/

#include <stdio.h>
struct node {
int value ;
struct node *next ;
} ;
extern struct node *mk_node(int v) ;
extern void print_list(struct node *head) ;
extern struct node *sort_list(struct node *head) ;
extern void free_list(struct node *head) ;
