Laoding a structure

[TankCDR]

Sorry about the last structure post. I was trying to just load the structure and go from there, but it was a very poor example.

The program attached compiles with no errors and no warnings. Basically I am trying to load the class.dat file into a structure. The class.dat file is delimited by a pipe "|".

LIKE THIS:
001635223|Stevens, Bill R.|COSC1400| |004760097|Smith, William O.|COSC1401| |006238033|Smithson, Thelma R.|ITSC1401| |


I have tried several ways to load this file into the "student" structure. The attached code is the closest that I have come. I sent the data to a report.dat file just to view the output and this is what it looks like:

001-63-5223 Stevens, Bill R COSC140 | |
047-60-097| mith, William OCOSC140 | |
062-38-033| mithson, Thelma RITSC140 | |
103-54-130| oodsen, Richard UITSC140 | |


The pipes are still there and the data is corrupted. I AM LOST!

Could anyone please help clarify my error(s)? If you know a better way, please give a brief example.

Thanks,
Alan

Ok, so fields are delimited by |
but are records delimited by newline (or anything)?

Eg, by newlines, the file would look like
001635223|Stevens, Bill R.|COSC1400| |
004760097|Smith, William O.|COSC1401| |
006238033|Smithson, Thelma R.|ITSC1401| |

In addition, what does "| |" mean - end of record, or just an empty field (containing what appears to be a space)

[TankCDR]

No, the record does not contain a newline/carriage return ''\n'

The | | is a 12 space field that is reserved for future use.

Here's something

#include <stdio.h>

// This uses a static buffer - you must use the result before
// calling this function again, otherwise the first result will be lost
// it also doesn't handle || as being an empty field
char *gettok( FILE *fp ) {
    static char buff[200];
    int i = 0;
    int ch;

    while ( (ch=fgetc(fp)) != EOF ) {
        if ( ch == '|' ) {
            break;          // end of field marker
        } else {
            buff[i++] = ch; // save the char
            buff[i] = '\0'; // and keep the buffer \0 terminated
        }
    }
    if ( i == 0 ) {
        return NULL;    // first read was EOF (or |EOF)
    } else {
        return buff;
    }
}

int main ( ) {
    FILE *fp = fopen( "member.txt", "r" );
    char *c;
    while ( (c=gettok(fp)) != NULL ) {
        printf( "Found '%s'\n", c );
    }
    fclose( fp );
    return 0;
}

Make sure it does all you want it to do, before burying it inside some larger program.
