Strtok, bubble sort, etc errors

[P3druh77]

Hi... i have a little problem on my code...

HI open a txt that have this:

LEI;7671;Maria Albertina da silva;[e-mail];
9;8;12;9;12;11;6;15;7;11;
LTCGM;6567;Artur Pereira Ribeiro;[e-mail];
6;13;14;12;11;16;14;
LEI;7701;Ana Maria Carvalho;[e-mail];
8;13;11;7;14;12;11;16;14;

--------------------------------------------------------------------------------

LEI, LTCGM are the college;
7671, 6567, 7701 is student number;
Maria, Artur e Ana are the students name;
[e-mail], ...@gmail are emails from students;
the first number of every line is the total of classes that students have;
after that is students school notes;

example:

College: LEI
Number: 7671
Name: Maria Albertina da Silva
email: [e-mail]
total of classes: 9
Classe Notes: 8 12 9 12 11 6 15 7 11.

My code:

Hi... i have a little problem on my code...

What's the little problem? You did state a question, nor did you point what are you having problem with.

Consider just the following in main.

int main(int argc, char *argv[])
{
    ALUNO alunos;
    FILE *fp;
    int tam==3;

    fp=fopen("example.txt","r");
    alunos = (ALUNO*) calloc (tam, sizeof(ALUNO));
    xml(alunos,nomeFicheiro, tam);
    system("PAUSE");
    return 0;
}

alunos is an structure, not a pointer. Then, you can not alunos = (ALUNO*) calloc (tam, sizeof(ALUNO)); and expect to work fine. Practice some more about allocating dynamic memory.

int tam==3; Not an assignment. Not quite a declaration.
When you fp=fopen("example.txt","r"); it's not optional to check if fopen() was able to get you the file successful. You must check, if it fails, create code that deals with the failure.

xml(alunos,nomeFicheiro, tam); according to your function accepts two parameter, not three. The first argument is the address or pointer to ALUNO which alunos is not. Of course, nomeFicheiro hasn't been declared yet.

system("PAUSE"); Works only in system that knows what "PAUSE" is. Can be substituted most likely by getchar();

Make sure you tag the code properly, next time. It is not (\code) as a closing tag, it is (/code)

Fix those errors and come back with specific questions about what you seem not to be able to figure out.
