编写了这个程序，它应该能够打印出 txt 文件中的所有行，但它只打印一个，现在已经看了 1 个小时，我找不到错误，任何帮助都会得到帮助！:)

您在每行输入末尾的出勤值导致您出现问题。您需要将其解析为浮点数或由句点分隔的两个小数，而不仅仅是一个小数。它应该与下面的代码更改一起工作，假设出席率永远不会达到一百万：

int valuesRead;
int attendance;
int attend1, attend2;
[...]
while ((valuesRead = fscanf(ifp, "%d %d.%d.%d kl. %lf %4s - %4s %d - %d %d.%d\n", &round, &dag, &month, &year, &clock, team1, team2, &goal1, &goal2, &attend1, &attend2)) >= 10){
    if (valuesRead == 11)
        attendance = attend1 * 1000 + attend2;
    else
        attendance = attend1;
    printf("runde %d den %d %d %d klokken %.2lf, mellem %s og %s endte %d - %d %d så kampen\n", round, dag, month, year, clock, team1, team2, goal1, goal2, attendance);
}

感谢您的输入，我现在可以正常工作了，只需将出勤变量更改为双精度，它就可以正常工作，再次提供代码，如果有人有任何技巧可以更聪明地编写它，请告诉我！:)

#include <stdio.h>
#include <stdlib.h>
#define MAX_LINE_LGT 200
#define NAME_MAX 200
#define TEAM_MAX 200

struct team{
char name[NAME_MAX];
int five_or_more_goals;
};
typedef struct team team;

void read_data_1(const char *file_name, team teams[]){
FILE *ifp;
char team1[NAME_MAX];
char team2[NAME_MAX];
int goal1, goal2;
int dag, month, year;
double clock;
double attendance;
int round;
team local_match;

ifp = fopen(file_name, "r");

while (fscanf(ifp, "%d %d.%d.%d kl. %lf %4s - %4s %d - %d %lf\n", &round, &dag, &month, &year, &clock, team1, team2, &goal1, &goal2, &attendance) == 10){
    printf("runde %d den %d %d %d klokken %.2lf, mellem %s og %s endte %d - %d %.3lf så kampen\n", round, dag, month, year, clock, team1, team2, goal1, goal2, attendance);
    }

fclose(ifp);

    }

  int main(void) {
  team all_matches_teams[TEAM_MAX];
  read_data_1("superliga-2011-2012", all_matches_teams);

  return 0;
  }
