c - 在 C 中使用 fscanf

Question

我正在尝试从文件中读入数组。我的名为 Players.txt 的文件包含:

Del Piero|3|Italy|Juventus|
Ronaldo|0|Portugal|Real Madrit

我使用了 fscanf ，但它没有正常工作，我没有做正确的转换。

谁能帮我读取它们并将它们存储到数组中。比如数组球员名字要包含{ Del Piero, Ronaldo}

#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <stddef.h>
#include <ctype.h>

#define NUM_PLAYERS 20
#define NAME_LENGTH 100
#define COUNTRY_NAME 20

int main (void)

{
    FILE *Players;

    char player_name [NUM_PLAYERS][NAME_LENGTH] = {0};
    char country_name[NUM_PLAYERS][COUNTRY_NAME] = {0};
    char team_name[NUM_PLAYERS][NAME_LENGTH] = {0};
    int goals_scored[NUM_PLAYERS] = {0};
    int i;

    Players = fopen("G:\\COP2220\\Project 5\\Players.txt", "r");
    if (Players == NULL)
    {
        printf("File not found.\n");
    }
    else

    {

       while (fscanf(Players, " %[^|]s %[^|]d %[^|]s %[^|]s",player_name[i],&goals_scored[i],country_name[i],team_name[i]))
       {
           printf("The player %s, scored %d from %s plays in %s\n", player_name, goals_scored,country_name, team_name );
       }
    }

   fclose(Players);
   return 0;
}

[] 本身就是一个类型，您不应该在它的结束。您真正需要做的就是将格式更改为:

"%[^|] | %d | %[^|] | %[^|]|\n"

并考虑更改您的 while 循环以在 fscanf 不返回 4 时中断。

这是一些工作代码:

#include <string.h>
#include <stdlib.h>
#include <stdio.h>
#include <stddef.h>
#include <ctype.h>

#define NUM_PLAYERS 20
#define NAME_LENGTH 100
#define COUNTRY_NAME 20

int
main (void)
{
    FILE * Players;
    char player_name [NUM_PLAYERS][NAME_LENGTH] = {0};
    char country_name[NUM_PLAYERS][COUNTRY_NAME] = {0};
    char team_name[NUM_PLAYERS][NAME_LENGTH] = {0};
    int  goals_scored[NUM_PLAYERS] = {0};
    int i = 0, ret = 0;

    Players = fopen("testfile", "r");

    if (Players == NULL)
        {
            printf("File not found.\n");
        }

    else
        {
            for (;;)
                {
                    ret = fscanf(Players, "%[^|] | %d | %[^|] | %[^|]|\n",
                            player_name[i],
                            &goals_scored[i],
                            country_name[i],
                            team_name[i]);

                    if (ret != 4)
                        {
                            printf ("only %d arguments were matched\n", ret);
                            break;
                        }

                    printf("The player %s, scored %d from %s plays in %s\n",
                            player_name[i],
                            goals_scored[i],
                            country_name[i],
                            team_name[i]);
                    i++;
                }
            fclose(Players);
        }
    return 0;
}
