从txt读取文件

Question

我有一个txt文件，我想从中读取数据。数据由项目输入组成，该输入具有以下属性：

numberofProjects
numofActivitiesperProject
numofResources
maxAvailableResources[numofResources]

，以及每项活动的持续时间和资源使用情况。例如，如果一个项目总共有30个任务，那么我们每30个任务有30个持续时间和资源使用，总数为numofResources。

我已成功从文本文件中读取以下内容，但无法读取其他信息。

numofActivitiesperProject
numofResources
maxAvailableResources[numofResources]

具体而言，我无法将数据读取到activityList [k]->duration和activityList [k]->maxResourceUse[j]。

问题是什么？

代码

int numofProjects;
int numofActivitiesperProject;
int numofResources;
int *maxAvailableResources;

typedef struct Activity {
    int id;
    int projectNo;
    int nofPre; //number of predecessors
    int nofSuc;
    int *precedessor; //precedence array
    int *successor; //successor array
    int duration;
    int *maxResourceUse; //resource usage if an activity
} Activity, PActivity;

Activity *activity;
Activity **activityList;

Activity *readFile(char *fileName) {
    int i = 0, j, k;
    int *numOfPres;
    int Total;

    FILE *fd = fopen(fileName, "r");
    if (fd == NULL) {
        printf("unable to open file %s\n", fileName);
        exit(1);
    }

    fscanf(fd, "%d%d%d", &numofProjects, &numofActivitiesperProject, &numofResources); 

    maxAvailableResources = (int*) malloc(sizeof(int) * numofResources);
    for (i = 0; i < numofResources; i++) {
        fscanf(fd, "%d", &maxAvailableResources[i]);
    }


    Total =numofProjects*numofActivitiesperProject;
    activityList = (Activity **) malloc(sizeof(Activity *) * (Total));
    activity=(Activity *) malloc(sizeof(Activity));
    numOfPres = (int *) malloc(sizeof(int) * (Total));
    activity->maxResourceUse = (int*) malloc(sizeof(int) * numofResources);

    for (k=0;k<Total;k++){
        //activityList [k]->duration = (int) malloc(sizeof(Total));
        activity->id=k+1;
        fscanf(fd, "%d", &(activity->duration));
        for (j = 0; j < numofResources; j++)
            fscanf(fd, "%d", &(activity->maxResourceUse[j]));
        activityList[k]=activity; //THERE IS A PROBLEM HERE...
    }

    }


    fclose(fd);

}   


void main() {
    readFile ("file.txt");
    _getch();
}

文本文件

读取输入的Txt文件：

10                  
10                  
6                       
11  9   7   9   11  20      
20  0   0   0   0   0   5 
goes on like this...

输入文件的格式如下：

Number of projects
Number of activities per project
Number of resources
R1 R2 R3 R4 R5 R6 ....Rk Total amount of each resource
Duration Activitity-1 of project-1,  Required resources of Activitity-1 of project-1
Duration Activitity-2 of project-1,  Required resources of Activitity-2 of project-1
...
Duration Activitity-n of project-1,   Required resources of Activitity-n of project-1
Duration Activitity-1 of project-2,   Required resources of Activitity-1 of project-2
...

...
Duration Activitity-1 of project-m,   Required resources of Activitity-1 of project-m
Duration Activitity-2 of project-m ,  Required resources of Activitity-n of project-m
