FILE READING/WRITING IN C

Program-1 • I used the dynamic allocation of STUDENTS object in main method and passed it as by reference in the function to assign the values. • I used the fopen in write mode only because in program 1, I only needed to write the content of my object to the file named as “marks_180706308.txt”. I used the separator “/n” to detect each attribute of my object so that I could be able to read the contents as well. • After successfully writing the contents, I closed the pointer that I used from fopen method. • The memory allocation for my object is dynamic. I could also allocate multiple instances dynamically by input or pre-defined, but in this problem, it wasn’t necessary so I created a single instance.

Program-2 • I created a function named as “Read_File” which I passed an object of student in which the values are to be written after reading from the file. • The memory allocation for my object is dynamic in the main method. • The pointer only open the file in “r” mode so that nothing can be written or appended in the file. • I used a char pointer to read each character from my read file and then append it the array of char unless a ‘\n’ (new line) is not found. • When the new line is found, the content is assigned to the object that is being passed by reference to the function. • A helper function is also used to append the character read from the file to the array of characters names as “arr”. • The Average_Calculator function is used to calculate the average and display the required output on the screen.
