Chapter 10, Problem 11E
Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer who created the file of names had a strange sense of humor and did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file, one name per line. For example, if the input file contains
Bob Jones Fred
Charles Ed
Marston
Jeff
Williams
the output file should be
Bob Jones
Fred Charles
Ed Marston
Jeff Williams

Suppose you are given a text file that contains the names of people. Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line. For example, if the input file contains
Ed
Marston
Bob Jones Jeff
Williams
Fred
Charles
The output file should be
Bob Jones
Ed Marston
Fred Charles
Jeff Williams
Use arrays to solve the problem.
The program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas).
If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show.
I need this answer in C language. Please explain nicely. Thanks.
Write a program to draw a quiz score histogram. Your program shouldread data from a file. Each line of the file contains a number in the range0-10. Your program must count the number of occurrences of each scoreand then draw a vertical bar chart with a bar for each possible score (0-10) with a height corresponding to the count of that score. For example,if 15 students got an 8, then the height of the bar for 8 should be 15.Hint: Use a list that stores the count for each possible score. An examplehistogram is shown below:
o o D D0 1 2 3 4 5 6 7 8 9 10

For example, in one class Amy will be at the front of the line and Yolanda will be at the end. Write a program that prompts the user to enter a number between 1 and 25 for the number of students in the class, then loops to read in that many names. Once all the names have been read in it reports which student would be at the front of the line and which one would be at the end of the line. You may assume that no two students have the same name.arrow_forwardJava Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…arrow_forward

Your program must contain at least the following functions: a function called GetData to read and store data into two arrays, a function called Average that is used to calculate the average test score and grade, and a function called PrintResults to output the results.
