C programing fopen

Programmer Question

 #include <stdio.h>
 #include <stdlib.h>
 typedef struct aluno{
                 char cabecalho[60];
                 char info[100];
                 int n_alunos;
                 char dados[100];
                 char curso[100];
                 int numero;
                 char nome[100];
                 char e_mail[100];
                 int n_disciplinas;
                 int nota;
                 }ALUNO;

void cabclh(ALUNO alunos[],int a){
   FILE *fp;
   int i;
   for(i=0;i<100;i++){
      fp=fopen("trabalho.txt","r");

   if(fp==NULL){
       printf("Erro ao abrir o ficheiro\n");
   }
   while(!feof(fp)){
       fgets(alunos[i].cabecalho,60,fp);
       printf("%s\n",alunos[i].cabecalho);
   }
}
fclose(fp);
}

what is wrong here?

main:

int main(int argc, char *argv[]){    
   ALUNO alunos[100];  
   int aluno;  
   int b;

   cabclh(aluno,b);

   system("PAUSE"); 
   return 0
