将文本文件读入结构数组C

Question

I have been stuck in trying to read this text file into array of structures.Here is a few lines from the text.

A|Boston Red Sox|Fenway Park|4 Yawkey Way|Boston|MA|02215|(617) 267-9440|redsox.com
N|St. Louis Cardinals|Busch Stadium|700 Clark Street|St. Louis|MO|63102|(314) 345-9600|cardinals.com

Here is the array of structures. I modified the text file so it only contains league and team name to make it easier to test changes.

#define LEN_LINE 80
#define LEN_NAME 30
#define MAX_LINES 60
#define LEAGUE_NAME 5

typedef struct
{
    char leagueName[LEAGUE_NAME + 1];
    char teamName[LEN_NAME + 1];


} team_t;

Here is where the problem lies.I have tried implementing strncpy() though being a beginner it has been hard trying to use the function correctly in this scenario.

FILE * filePtr;
    int index, count;
    char line[LEN_LINE + 1];
    team_t teams[MAX_LINES];
    filePtr = fopen("MLBteams.txt", "r");
    if(filePtr == NULL)
    {
        printf("Unable to open file.\n");
    }
    else
    {
        index = 0;
        while(index<MAX_LINES && fgets(line, LEN_LINE, filePtr))
        {
            if(2 == sscanf(line,"%s %s", teams[index].leagueName, teams[index].teamName)

               )
            {
                index++;
            }
        }
        fclose(filePtr);  

I looked through other threads though they've only confused me.

Answer 1

From your example of the content of the text file, you have a splitter as | symbol ( A|Boston Red Sox ). You need to put it inside sscanf:

if(2 == sscanf(line,"%s|%s", teams[index].leagueName, teams[index].teamName))
{
                index++;
}

Ok. Since there are spaces in your strings, you can parse manually its not hard. Instead of code abow do this:

char *league_p = strchr(line,'|');
int len = league_p - line;
char *league = calloc(len, 1);
memcpy(league,line,len - 1);
league_p++;
char *team_p = strchr(league_p,'|');
len = team_p - league_p;
char *team = calloc(len, 1);
memcpy(team,league_p,len - 1);

This way you will always get first two values splitted
