Qn 1. Write a complete C program (10 Marks) Create a text file that contains four columns and ten rows. First column contains strings values, second and third column contains integer values, and fourth column contains double values (you are free to use your own values). Declare a structure that contains 4 elements (you are free to use your own variables). First element should be a char array to read first column values from the text file. Second element should be an int value to read second column values from the text file. Third element should be an int value to read second column values from the text file. Fourth element should be a double value to read third column values from the text file. Declare an array of this structure with size 10 and read the contents of the text file into this array. Then prompt the user with the following instructions: 1: Display the details of the array call a function to display the contents of the array on screen. 2: To sort the array (you should call sort function output of the sorting function should be written onto a text file and terminal) You should give the user the chance to sort in ascending or descending order with respect to string value. Then you should give the user the option to select from different sorting techniques (you should write minimum two sorting algorithm functions, call the functions according to the choice the user enters call the sorting function only after the user selects the above-mentioned options). 3: To search for a string element (Write the output on terminal) You should give the user to select the searching technique (linear or binary must use recursive version of the searching functions) if binary is selected call a sort function first. 4: To insert these array elements into a linked list in the order of string values. Display the contents on the terminal. 5: Quit Your complete program should have multiple files (minimum two .c files and two .h files). Give your file name as heading and then paste your code. You must include your text files as well in the submission.
