[SOLVED] IT1010 - Lab Sheet 7 - Introduction to Programming

Description

At the end of this class the students will be able to

• Create a sequential access file to store and retrieve data.
• Store data into a sequential file.
• Retrieve data from a sequential file.

Exercise 1

A university needs to maintain a text file to store and retrieve their student’s details such as name, class, year and total marks.

1. Write a C program to do the following;
2. Create a file pointer

FILE *fPtr;

1. Open the file to write data

fPtr = fopen ( “Student.dat”, “w”);

1. Input the data of 5 students from the keyboard and store in the file. Write the data

to the file using

fprintf(fPtr, “%s %c %d %d \n”, name, class, year, GPA);

1. Modify the program to open the “Student.dat” file you created above and print the data in a tabular form as shown below in the screen.

Name              Class              Year              GPA                                           

Nimal                 1                     1                   3.7

Sunil                 1                     2                   4.0

Kamal                 3                     3                   2.7

Mihiri                 2                     1                   1.7

Mala                  2                     4                   2.1

Exercise 2

Write another program to read the “Studnet.dat” file and display name and GPA of the students in a given year. The user should be able to input the year from the keyboard.
