- The stream member function rdstate returns the current state of the stream T/FRead Data Write a function that reads in data from a file using the prototype below. The function can define and open the file, read the names and marks into the arrays and keep track of how many names there are in numElts, and then closes the file. The list of names and marks can be found at the end of the lab and copied into a text file. void getNames(string names[], int marks[], int& numElts); Display Data Write a function to display the contents of names and marks using the prototype given below. void displayData(const string names[], const int marks[], int numElts); Linear Search Write the searchList function given the prototype below so that it searches for a given name. The functions returns and int which is the index of the name found. The main program will decide if -1 is returned then it will say name is not found otherwise it will write out the name and the mark for that name. int linearSearch(const string list[], int numElts, string value);…The stream member function flags with no arguments resets the stream’s format state.

WarningWrite a program that will read in a file of student academic credit data and create a list of students on academic warning. The list of students on warning will be written to a file. Each line of the input file will contain the student name (a single String with no spaces), the number of semester hours earned (an integer), the total quality points earned (a double). The following shows part of a typical data file:Smith 27 83.7Jones 21 28.35Walker 96 182.4Doe 60 150The program should compute the GPA (grade point or quality point average) for each student (the total quality points divided by the number of semester hours) then write the student information to the output file if that student should be put on academic warning. A student will be on warning if he/she has a GPA less than 1.5 for students with fewer than 30 semester hours credit, 1.75 for students with fewer than 60 semester hours credit, and 2.0 for all other students.
