我学习 C 编程已经有一段时间了，我遇到了一个我觉得很难解决的任务，因为我根本不知道如何继续。基本上，我必须查找并打印那些进球数达到 7 个或更多的比赛从附加的文本文件中获取信息。我不知道该怎么做。
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LINE 500 /* MAX NO. OF CHARACTERS FROM THE WHOLE FILE */
#define MAX_NAME 100 /* MAX NO. OF CHARACTERS OF WEEKDAY, HOME- AND GUEST TEAM */
/* DATA STRUCTURES */
struct match {
char weekday[MAX_NAME];
int date;
int the_time;
char home_team[MAX_NAME];
char guests[MAX_NAME];
unsigned int home_goals;
unsigned int guest_goals;
unsigned int spectators;
};
typedef struct match match;
/* FUNCTION PROTOTYPES */
int read_file(const char *file_name, match matches[]);
/* MAIN FUNCTION */
int main() {
return 0;
}
/* FUNCTIONS */
/* function to read the given text-file */
int read_file(const char *file_name, match matches[]) {
FILE *ifp;
int match_nbr = 0;
match games;
ifp = fopen(file_name, "r");
if(ifp != NULL) {
while(fscanf(ifp, "%s %d %d %s %s %d %d %d", games.weekday, &games.date, &games.the_time,
games.home_team, games.guests, &games.home_goals,
&games.guest_goals, &games.spectators)) {
matches[match_nbr] = games;
match_nbr++;
}
fclose(ifp);
}
else {
printf("The file could not be opned %s\n", file_name);
}
return match_nbr;
}
我还没有打开并读取该文件。我认为这应该发生在主函数中，但这基本上是我到目前为止编写的代码。我尝试让它工作，但没有任何作用，所以我希望有人可以帮助我。此时我真的不知道如何继续，什么应该进入 main 函数，什么不应该进入。
我不知道该上传到哪里，希望这个能用 D:

一切正常，我在 fgets 读取的行上使用了 sscanf
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_LINE 500 /* MAX NO. OF CHARACTERS FROM THE WHOLE FILE */
#define MAX_NAME 100 /* MAX NO. OF CHARACTERS OF WEEKDAY, HOME- AND GUEST TEAM */
/* DATA STRUCTURES */
struct match {
char weekday[MAX_NAME];
int date;
int the_time;
char home_team[MAX_NAME];
char guests[MAX_NAME];
char dash[1];
unsigned int home_goals;
unsigned int guest_goals;
unsigned int spectators;
};
typedef struct match match;
/* FUNCTION PROTOTYPES */
int read_file(const char *file_name, match matches[]);
/* MAIN FUNCTION */
int main() {
match matches[1024];
int match_nbr = read_file("superliga-2014-2015.txt",matches);
printf("number of matches: %i\n",match_nbr);
return 0;
}
/* FUNCTIONS */
/* function to read the given text-file */
int read_file(const char *file_name, match matches[]) {
FILE *ifp;
int match_nbr = 0;
match games;
ifp = fopen(file_name, "r");
char line[2048];
while (fgets(line, sizeof line, ifp) != NULL) {
sscanf(line, "%s %s %lf %s %s %s %d %s %d %d", games.weekday, &games.date, &games.the_time,
games.home_team, games.dash, games.guests, &games.home_goals,
games.dash, &games.guest_goals, &games.spectators);
if (games.home_goals + games.guest_goals > 6 )
printf("%s vs %s \n",games.home_team,games.guests);
matches[match_nbr] = games;
match_nbr++;
}
return match_nbr;
fclose(ifp);
}
结果:FCM 与 RFCFCM 与 RFCEFB 与 SIF比赛数量:230

我是一名优秀的程序员,十分优秀！
