如何在单独的行中从文件中读取字符串和整数

Question

so I have been searching your website and im still very unclear on how to do this, so let me try to explain this as best I can.

I have a input file like so:

2
Joe Flacco
1 3 5 6 7 8
Tom Brady
7 9 10 15 52 53

The first number is the number of "people" in the file, and the next is their first and last name. Next is 6 ints between [0,53] that are their "lottery" numbers. Anyways, I can get my code to pull in the first number, but getting theirs names and numbers is proving hard.

The last part, is getting it to fit in the struct we have declared (which we must use, that contains variables firstName[20] lastName[20] and numbers[6]. I know I am way off on how to do this all properly, but I am posting my code so you guys can see what Im doing. I appreicate any and all help. Also, Im trying to learn how to do it, not get you to right a program for me, so any explanations are very welcome.

for(int i=0; i < numPlays;i++)
{   
        char firstName[20];
        char lastName[20];
        for(int x=0; x<3;x++)
       fscanf(fr, "%c", &firstName[x]);
       for(int x=0; x<6;x++)
       fscanf(fr, "%c", lastName[x]);   
        for(int g=0; g<6; g++)
        {
        fscanf(fr, "%d", &Steve.numbers[g]);
        }
        temp[i]= Steve;
            //Tester code, lets hope this works
        for(int x=0; x<3;x++)
        printf("The persons name is %c.\n",&firstName[x]);
        //printf("The persons last name is %c.\n",temp[i].lastName);
}

Answer 1

Using fgets strtok and atoi will give you what you need. As for your program's structure, you probably want something like this:

typedef struct Player {
    char name[20];
    int numbers[6];
} Player;
#define SIZE(x) (sizeof(x)/sizeof(*(x)))

Player readplayer(){
      Player p;
      int x;
      char * num;
      //read a line with fgets;
      //memcpy() to p.name;
      //read another line
      for(num=strtok(line, " "),x=0;x<SIZE(p.numbers);x++, num=strtok(NULL," "))
          p.numbers[x] = atoi(num);
      return p;     
}

int main()
{
     //read a line with fgets
     int x, nplayers = atoi(line);
     Player *players = malloc(nplayers*sizeof(Player));
     for(x=0;x<nplayers;x++)
         players[x] = readplayer();
}

Answer 2

you can use fgets() function for this purpose. it will read lines as String. after reading the numeric as string, just convert it to integer.

您可以将读取文件和分析内容分开， 例如 ，定义readline()并独立分析每一行， 例如example 。
