I do not understand what I am doing wrong with the writing of the text files, since I get many warnings. Can someone help me know what I'm bugging him about?

fread(&reg,1,sizeof(info),fp);
while(!feof(fp))
{
    fprintf(fpTextFijo,"%*ld%-*s%-*s%*f\n",SIZE_DNI,reg.dni,SIZE_NAME,reg.name,SIZE_SURNAME,reg.surName,SIZE_AVERAGE,reg.average);
    fprintf(fpTextVar,"%ld|%s|%s|%f\n",reg.dni,reg.name,reg.surName,reg.average);
    fread(&reg,1,sizeof(info),fp);
}

You need to prepend a . in the specifier * .

Its correct use is: .*

Try modifying your line of code in the following way and several of your warnings should be solved:

fprintf(fpTextFijo,"%.*ld%-.*s%-.*s%.*f\n",SIZE_DNI,reg.dni,SIZE_NAME,reg.name,SIZE_SURNAME,reg.surName,SIZE_AVERAGE,reg.average);
