parameter passing

I am building a student registration system for college





The implementation must contain:



(1.1) Creation of the constructed record type - with at least 5 variables, three of which have different primitive data types -, declaration of the vector variable of the constructed record type (with at least 3 indices), and registration function WITH PAIR PASSAGE METROS (reading data from the keyboard) using a vector of records (heterogeneous composite variable) - being mandatory the use of a repetition loop to load the vector -. The registration must be done in the registration vector and then stored in a file (text or binary).



(1.2) Function WITH PASSING OF PARAMETERS for querying data within the record vector, containing - at least - a conditional structure with three different conditions separated by two logical operators (as well as the guidelines of Work 1). The query must be made in the content previously recorded in the file (text or binary).



(1.3) Function WITH PASSAGE OF PARAMETERS to print a complete report of the data registered in the record array. Printing must be done from the content previously recorded in the file (text or binary).



(1.4) The array variable(s) of records and the file variable(s) MUST be declared LOCAL.



(1.5) Among the passages of parameters, MUST be included, at least, by REFERENCE. At least one of the functions must return.

I would like to know if my code follows what is being asked



I would like to know what is wrong in the parts below:



cadastro(&arq, escolar);



}while ((op == 0) && (i == 1));XXXXXXXXXXXXXXXXXXXXXXXXXXXXXX



arq3 = fopen("", "r");



strcmp(&escolar3[i].nomeAluno[40], &nomeConsulta[40]) == 0)



fscanf(arq2, "%s ", escolar2[i].nomeAluno);



If you don't understand, just tell me if the parameter is being passed and if the file was created correctly. If not how to resolve.
