- C++ Programming: How would you write a function that takes a filename and an array of struct time, opens a file, reads each line in the file as the number of days, converts this to a struct time and stores this is in an array? Here is my code so far (p.s. the function i need help with is called void readData): #include<iostream>#include<string>#include<fstream>#include<cstdlib>#include<vector> using namespace std; struct time{// private:int years, months, days;//public: time(){}time(int days){}}; time getYearsMonthsDays(int days){time x;x.years = days/450;days = days%450;x.months = days/30;x.days = days%30;return x;} int getTotalDays(time x){int totalDays;totalDays = x.years*450 + x.months*30 + x.days;return totalDays;} void openofile(string ofilename,ofstream &fout){fout.open(ofilename.c_str());if(!fout){cout << "Error opening output file..." << endl;exit(1);}} void openifile(string ifilename,ifstream...arrow_forwardMy professor told me to write a program that: includes a function that reads integers consisting of students’ test scores in the range of 0-200 from a file into a one-dimensional array of size 30 includes a function to calculate and print the mean includes a function to calculate and print the standard deviation includes a function to determine the number of students having scores in each of the following ranges: 0-24, 25-49, 50-74, 75-99, 100-124, 125-149, 150-174, 175-200 and output each score range followed by the number of students within that range using C++ The following data is given by text, so the code has to read the following data 76, 89, 150, 135, 200, 76, 12, 100, 150, 28, 178, 189, 167, 200, 175, 150, 87, 99, 129, 149, 176, 200, 87, 35, 157, 18arrow_forwardWrite code to declare array that contains names of 7 stores. Then write a statement that will call a function that will return the name of the store randomly.arrow_forward
- 6) Write a program that declares a 10-element integer array. Initialise the arrays with the values: 10, 20, 30, 40, 50, 60, 70, 80, 90, 100 using a for loop. Then output the array values.arrow_forwardWrite a C code which asks a user how many numbers (up to 100) they want to enter. The program then stores the data in an array and sends it to a function to compute the average of the numbers of the array. The function should then return the average and the program should then print the average.arrow_forward
