i can't display the outputs.
like when i entered all the data 5times in the getrecord()
when it goes to the function displayreverse after inputing all the needed data, it does not display all the output. the output is just

" idno. lstnme prelim midterm fgrde"

and the inputted data didn't appear at all even though i entered all the data needed

Here are some problem with your code

1)
C Syntax (Toggle Plain Text) 
  1. printf("last name:");
  2. scanf("%s",ln[i]);

replace it like
C Syntax (Toggle Plain Text) 
  1. printf("last name:");
  2. scanf("%s",ln);

2) The same problem with other scanf also. Give address to scanf.
ex :
C Syntax (Toggle Plain Text) 
  1. scanf("%d",&(pr[i]));

my problem is not in inputting the data, but in displaying the outputs.
like for example:

when i input all the data: like
id number:1
lastname:smith
prelim:60
midterm:100

id number:23
lastname:wirth
prelim:65
midterm:100

id number:3
lastname:smith
prelim:60
midterm:76

id number:3
lastname:taylor
prelim:55
midterm:15

id number7
lastname:scott
prelim:6
midterm:10

so i get a 5 inputs,and then after inputting it should display all these data in the screen.

Try changing this part in displayreverse()
void displayreverse()
{
    int i,p;
    printf(" idno.  lstnme  prelim  midterm  fgrde");
    for(i=4;i>=0;i--);
    {
Please do not use clrscr, and gotoxy. Those functions are not standard functions. Since you are obviously a student, try to learn the correct usage of the C language. Modern compilers which are more standard compilant than TurboC does not compile your program. Search for the DevCPP compiler in google and download it. It is a very good compiler for beginners.
