Please write the code in c DescriptionWrite a program to compute average grades for a course. The course records are in a singlefile and are organized according to the following format: each line contains a student's firstname, then one space, then the student's last name, then one space, then some number ofquiz scores that, if they exist, are separated by one space. Each student will have zero toten scores, and each score is an integer not greater than 100. Your program will read datafrom this file and write its output to a second file. The date in the output file will be nearlythe same as the data in the input file except that you will print the names as last-name, first-name; each quiz score, and there will be one additional number at the end of each line:the average of the student's ten quiz scores.Both files are parameters. You can access the name of the input file with argv[1]. andthe name of the output file with argv [2].The output file must be formatted as described below:1. First and last names appear togeter in a left-justified column that is 20 characters widewhere the last name comes first and a space and then the first name. Read each nameseparately and then put them together into a larger correctly formatted string beforetrying to output them (you can use the concatenate two strings example in class as areference).2. Each quiz score should be listed in a right-justified column that is 4 characters wide.Note that if a student has fewer than 10 scores (they have missed one or more of thequizzes), your program will need to display the missing score(s) using 0 for each one.3. The average should appear in its own column that is 10 characters wide. Note that if astudent has fewer than 10 scores, the average is still the sum of the quiz scores dividedby 10.4. The average should be computed with an accuracy of two decimal places.You should use at least two functions that include FILE handles in their parameter lists.(These functions may have other parameters as we Suggestion: One very useful strategyis to write a function that, given a FILE pointer, will extract out exactly one person's nameand write it to the output file. Write another function that, given a FILE pointer will extractout one person's quiz scores and list them in the output file along with the average score.Then use these two functions in a loop that will keep doing this until there is no more datain the input file. The feof function may be helpful for determining if you have reached theend of the input file.You may not use %s together with scanf (or fscanf) or gets, which are not safe aswe mentioned in class. Don't use any library functions related to c-strings, e.g. strcpy,strlen, atoi,itoa, for the purpose of practice. You don't need to and should not use anynon-string arrays.
