Program over reads text file when passing it to an array

Question

13 Years Ago

I am making a program that reads football player stats from a file and places it in an array
how ever my program seems to over read the file which has the stats of 17 players and it makes an array of 101 players with the first 17 being alright and the rest being filled in with spaces and random characters and symbols such as spades
can someone help me fix this
here is the player structure and read data function

typedef struct player
{
int number, atmp, yards, TD;
char fname[30];
char lname[30];
char pos[4];
} playerdata;

/* Begin Read Data function */
void readdata(playerdata player[],
int size)
{
FILE *fptr;

if ((fptr = fopen("C:/Documents and Settings/Owner/Desktop/Jason/C programing/assignment6/assignment6data.txt", "r")) == NULL)
{ printf("Error: the file cannot be opened\n");
}
else
size;
int i;
for (i = 0; i < size; i++)
{
fscanf(fptr, "%s %s %s %s %s %s %s", &player.number, &player.fname,
&player.lname, &player.pos, &player.atmp, &player.yards,
&player.TD);
}

}

First - that's not a program you posted, or a snippet of code that will run.

Second - you NEED to use CODE tags. Click on the icon in the forum's editor and paste your code, between the tags it provides you.

Third - you didn't give size a value, but you use it to stop the for loop. ??

Fourth - [B]Welcome to the forum, Bkoper![/B] ;)[CODE ] icon in the forum's editor and paste your code, between the tags it provides you.

Here is the whole code , take note that some things are left in it from an alternate version that i am currently modifying, the case 1 of the switch is what i am currently trying to get right, case 2 will constantly display the first quarterback for some reason

Hi koper,

You declared size as int in main function without defined..

here is the data to test with

and as you may have already guessed, i am not an experienced programmer
this is a class assignment

Hi koper,

The below code works fine...just test with your requirments.

The following are some of errors u did in your code

You didn't defined value for size in main function but passed in readdata function
In switch case you didn't break the while loop after it reached the false condition

Change the value of size depends on your requirements

#include<stdio.h>
#include<string.h>
 
typedef struct player
{
	int number, atmp, yards, TD;
	char fname[30]; 
	char lname[30];
	char pos[4];     
} playerdata;

//#define size sizeof(playerdata);
 
 
char number[3], atmp[4], yards[4], TD[4];
char fname[30]; 
char lname[30];
char wname[60];
char pos[4];
char playerarray[50];
 
int request;

 
 
/* Begin Read Data function */
void readdata(playerdata player[],int size)
{
    FILE *fptr;
 
 
     if ((fptr = fopen("assignment6data.txt", "r")) == NULL) 
	 { 
		 printf("Error: the file cannot be opened\n");
     }
     else
	 {
		int i;
		for (i = 0; i < size; i++)
		{
			fscanf(fptr, "%s %s %s %s %s %s %s", &player[i].number, &player[i].fname, 
			&player[i].lname, &player[i].pos, &player[i].atmp, &player[i].yards, 
			&player[i].TD);			
		}
	  }
 
}
/* End Read Data */
