大家好，我做了有一个月，问了好多人，还是Ouput wrong . short form 的
Attendance.txt
1 1 0
1 0 1
1 1 1
0 1 1
0 0 1
0 1 0
0 0 1

#define MAX_WEEKS 7
#define MAX_STUDENTS 10

int studCount,weekCount;
int Attendance[MAX_WEEKS][MAX_STUDENTS];
variable 有。。。。可以assignvalue

void Read_Attendance_Into_Array()
{
FILE*fp;

int total_present=0;

fp=fopen("Attendance.txt","r");

if (fp==NULL)
{
printf("Error\n");
exit(-1);
}
else
{
printf("Reading Attendance details for Week #\n");
printf("0...1...2...3...4...5...6...\n\n");
printf("Attendance for each week\n");
printf("------------------------\n");

while (fscanf(fp,"%d",&student)!=EOF)
{
for (weekCount=0;weekCount<MAX_WEEKS;weekCount++)//MAX_WEEKS 7
{
printf("Week NO %d :",weekCount+1);

for (studCount=0;studCount<MAX_STUDENTS;studCount++)//MAX_STUDENTS 10
{
fscanf(fp,"%d",&Attendance[weekCount][studCount]);

if (Attendance[weekCount][studCount]==1)
{
total_present=total_present+1;
}
}
printf("%d students present\n",total_present);
total_present=0;
}
printf("\n");
}
}
fclose(fp);
}

我的output
week 1          7
week 2          4
week 3          0
week 4          0
