(FRP7) Write a function that reads data from a file. The file has already been opened and verified. The data should be saved in the array of type ship. The size of the array is passed in the int parameter and the number of records read is return in the last parameter, by reference. The file should be read until end of file has been reached or the array is full.
struct ship{ string shipCaptain; string shipName;
};
The function prototype isvoid readFile( ifstream&, ship[ ], int, int& );
ifstream - The already open file
ship[ ] - array of structs where the data from the file will be stored.
int - the size of the array.
int& - the number of records read from the file. This value is set by the function before returning
return- the number of records read from the file, returned by the function.
The amount of data in the file is unknown but there is no bad data. The file format is the shipsName followed by the shipsCaptiain .

- This program will calculate the total amount a customer has to pay based on their order of fruit juice. ∙ Create a text file as shown below. Name the file as menu.txt. The content of the file represents the juice code, juice name and juice price. ∙ Create a FILE pointer called fread. Use this pointer to open the file menu.txt for reading. ∙ Ask the user to enter the juice code and number of glasses. ∙ Identify the price of the juice the customer ordered. ∙ Calculate the total payment and display the bill. ∙ If the joice code entered is wrong, display “The Juice Code is INVALID. Order is cancelled!”. ∙ Display the output as shown below.

Input Validation: The program should not accept quantities, or wholesale or retail costs, less than 0.The program should not accept dates that the programmer determines are unreasonable.arrow_forwardArray/File FunctionsWrite a function named arrayToFile. The function should accept three arguments:the name of a file, a pointer to an int array, and the size of the array. The functionshould open the specified file in binary mode, write the contents of the array to the file,and then close the file.Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. Thefunction should open the specified file in binary mode, read its contents into the array,and then close the file.Write a complete program that demonstrates these functions by using the arrayToFilefunction to write an array to a file, and then using the fileToArray function to readthe data from the same file. After the data are read from the file into the array, displaythe array’s contents on the screen.arrow_forward
- Body Mass Index Write a program that reads names, weights, and heights from bmi.dat (provided with starter code; do not change the file name). Use the information to calculate and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula: BMI = weight × 703 / height2 where weight is measured in pounds and height is measured in inches. The file is in the format name weightInKG heightInCM You will read the name, weight and height for 4 people from the file, and you will need to convert the weights in the file to pounds (note that 1 kilogram = 2.2 pounds) and the heights to inches (2.54 cm = 1 inch). The program should display the person's name along with the calculated BMI and a message indicating whether the person has optimal weight, is underweight, or is overweight. Your output should look like A person’s weight…arrow_forwardA file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file.

- 1. Write a program named program61.py This program will have three functions, the main() create() and retrieve(). main() will call: create() and main() then calls retrieve() create() will prompt the user to enter any number of course name | grade values. The course name ,AND calculated class GPA ( not the class grade ) are the written one value per line to a file named grades.txt ( review example of grades.txt below! ). Pressing Enter with no input value on the course name will exit the loop, close the file, print "File was created and closed" and return the bool value True to the main(). See Simple GPA Tip below. retrieve() will open and read grades.txt. The function then will print the course names and Class GPA as shown below. The average of all class GPA values should be calculated and displayed to two decimal places and then return variable used for the GPA average to the main() .

Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: Read the file name of the tsv file from the user. Open the tsv file and read the student information. Compute the average exam score of each student. Assign a letter grade to each student based on the average exam score in the following scale: A: 90 =< x B: 80 =< x < 90 C: 70 =< x < 80 D: 60 =< x < 70 F: x < 60 Compute the average of each exam.
