- Write a program that reads a list of enrollments from a file and prints a class roster for the teacher. Make the class roster line up as neatly as you can and still fit on the screen. You can choose the actual values to use for your data. Make sure to do enough sets of data to well test your program! (Empty data set, normal data set, data with large values, data with short values, etc.) Also, your program can't know ahead of time how many people are enrolled in the class... Don't forget to read the file's name from the user and protect your program against any errors that may occur during the opening of the file. Try to use functions to break up the program into more manageable pieces. USING C++ As an example, you might have the data file contain:arrow_forwardC++ Implement a standard trie for a set of ASCII strings including a terminating character $ for each word. Create a class that has a constructor that accepts the name of an input file as a parameter (a string), and the class should have an operation that test whether a given string is stored in the trie. The driver should allow user to specify the input data file, output number of words in the trie, and then use a y/n loop to check for a few words. Output yes or no for each search word. You should format your input file's words to lowercase and remove extra characters like comma, periods, etc.arrow_forwardWrite a program that reads a list of enrollments from a file and prints a class roster for the teacher.

- Write a program in Python that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. 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 .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • 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 • Output the first names, last names, exam scores, and letter grades of the students into a text file named…arrow_forwardI have a text file and I want to read it in C++. variables to use: fname, lname , Id nr, Gender and all third line which is an address The file is : Tommy James 23456731667 Streetname 45 , 154 23 Georgia John Andersson 3456723464 Streetname 12 , 231 32 Las Vegas Kim Larsson 3456312653 Streetnamn 15, 231 56 Florida If we Said the 8th digit in ID number is showing the Gender of the person.

I have a hard time to figure how I can do the third line in the file. They read to word Las and then the compiler shows terminate called after throwing an instance of ' std::invalid_ argument ' what (): stoi aborted so I figured that the problem I have in one line the city is two word.arrow_forwardQuestion 2: Write a program to read student ID and check whether it is odd/even number. Output a 4X4 badge if the student ID is even number and output a 3X3 badge if it is odd number. The badge is built up by the (height X width) of asterisks. (Use for-loop to draw the asterisks, do not hard-coded)arrow_forward
- Write a program that creates the multi-panel plot shown below, for Planck curves at 4 different temperatures Planck Curves Use embedded noninteractive plotting and set the figure size to be 10x5 inches. • You may write your program in a single cell, or break it over multiple cells. Use a logarithmic x axes, and the logspace() function for generating the axes values. You will have to be careful with units on this one. For 50% extra credit have your program use a loop over the four axes, with all the plotting code contained within the loop (except for any subplot adjustments). 0.030 12 300K 1000K 0.025 10 0.020 FBBX (Wm-nm-1) FBBA (Wm-2nm-¹) 0.015 10 0.010 0.005 2 0.000 A (nm) λ (nm) 100000 3000 3000K 6000K 2500 80000 2000 60000 FBBA (Wm-2nm-¹) FBBX (Wm-2nm-1) 1500 40000 1000 20000 500 0 101 102 0 101 103 104 105 106 102 103 104 105 106 X (nm) λ (nm) python languagearrow_forwardWrite a program that receives a coded message file(Lab3ExtraCreditCT.txt) from your local espionage agent and decodes it into a file using standard English. The problem is your agent forgot to tell you the key used to decode the message. Fortunately, this is a simple substitution code consistently using 1 alphanumeric character to represent another, this is case sensitive. All other characters are not substituted, so a space will always be a space, a – will always be a –, a @ will always be a @, etcetera.

In order to change colors, you must first use the GetStdHandle function to get a handle to the console, which is similar to getting a file pointer before working with a file. It is done e.g. as follows: HANDLE hConsole; hConsole = GetStdHandle (STD_OUTPUT_HANDLE); The above functions are defined in windows.h Tip 2: Write a utility to find out the colors corresponding to all combinations from 0 to 255.
