Write a program that reads student data from a file, compute their GPA and writes the results to a different file.
1. The user should have the option to either enter their text file that contains the student grades or use the provided text file that contains theinformation.
The data in "indata.txt" should look similar to this,
Lara_Croft75 70 91 69 89Chris_Redfield68 88 79 85 94Johnny_Cochran69 98 95 77 80Wanda_Maximoff84 86 98 95 92Luke_Skywalker74 96 80 98 97William_Kurt89 52 99 81 58Samuel_Jackson50 96 50 64 95END_OF_FILE
This is supposed to be in python. This is what I have so far. I have no experience I apologise. I am trying to finish the GPA calculating program currently but am having trouble finishing it.
grade = input("enter grades")points = 0
if grade is 90-99:total_points = 4.0if grade is 80-89:total_points = 3.0if grade is 70-79:total_points = 2.0if grade is 60-69:total_points = 1.0if grade is 50-59:total_points = 0.0gpa = total_points/len(grade)print(gpa,"is gpa")
Write a program that expands on the below program by reading each line in the file, and displays all of the lines read from the file to the screen before closing it. The code for this will occur after the code that prints a message confirming that the file has been opened successfully above and before closing the file.Program should then output the number of lines in the file. Test the program by creating a text file with at least 5 lines of text (of any composition).
#include<stdio.h>
char c;
int main (int argc, char **argv) {FILE* f;
if (argc != 2) { printf("No filename in the argument");return 1;}
f = fopen(argv[1], "r");
if (f == NULL) {printf("The file cannot be opened successfully: %s\n",argv[1]);return 1;}
printf("The file has been opened successfully\n");
while( c != EOF) { c = fgetc(f); //read from file printf("%c",c); //display on screen }
fclose(f); }
Write a program, and store it in a file called Travel Expenses.xlsm, that does the following: (a) It asks for a person’s first name and stores it in firstName; (b) it asks for a person’s last name and stores it in lastName; (c) it asks for the number of miles the person traveled on a recent trip and stores it in nMiles; (d) it asks for the average miles per gallon the person got on the trip and stores it in milesPer- Gallon; (e) it asks for the average price per gallon paid for gas on the trip and stores it in avgPrice; (f) it calculates the cost of the trip and stores it in tripCost; and (g) it displays a message such as "Bob Jones traveled 800 miles, got 31.3 miles per gallon on average, paid $3.49 per gallon on average, and paid a total of $89.20 for gas." Make sure there is an Option Explicit line at the top of the module and that you declare all of your variables appropriately.

- Write a program that asks any number of students to enter their final grade and enables you to store these grades into a grades.txt plain text file. Then it reads the grades from the grades.txt file, and displays the individual grades and their count and average.arrow_forwardWrite a program to compute Letter grades for a course. The course records are in a file that will serve as the input file. Each line of the file contains a student’s last name, then one space, quiz scores, All on one line. The program should ask the instructor about the grading scheme. Based on the input grades and the grading scheme, the system will print out for the instructor the final letter grades for all students. The instructors can choose an option to save all the grades in a text file.arrow_forwardWrite a program that opens a text file called quiz.txt for reading. This file contains a single linewith a student’s first name then one space, then the student’s last name, then one space, then somenumber of quiz scores that, if they exists, are separated by one space. The student will have betweenzero and ten scores (inclusive), and each score is an integer between 0 and 100 (inclusive). The filemay or may not end with a new line character. Your program will read the data from this file andwrite its output to a second file. The data in the output file (named average.txt) will contain thestudent’s quiz scores followed by the average of the student’s quiz scores.The output file must be formatted as described below.1. Each quiz score should be listed in a right-justified column that is 4 characters wide. Notethat if a student has fewer than 10 scores (they have missed one or more of the quizzes), yourprogram will need to display the missing score(s) using 0 for each one.2. The average…arrow_forward
- Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.arrow_forwardCreate a text file of names, (3 names per line, 5 lines in total) followed by an age for each name. Go through the file and sum the ages. Create an output file with each persons name followed by age and then a line at the end of the output file that says “sum of all ages is: x”. Simple Java programming. Should include things like bufferedReader, fileReader, printWriter, fileWriter, file close, try-with-resources, Scanner, catch/try, etc. Include Java file and txt file. Thank you.arrow_forwardCreate a program that calculates the average test scores. Given the student’s name and five test scores, calculate the test scores. The student’s name, five test scores and the average test score is stored in the file testaverage.txt. The data is input from the file test.txt.

- Write a program that queries information from three files(given to you). The first file contains the names and telephone numbers of a group of people. The second file contains the names and Social Security numbers of a group of people. The third file contains the names and annual income of a group of people. The groups of people should overlap. Your program should ask the user for a telephone number and then print the name, Social Security number, and annual income, if it can determine that information. Sample run1: Enter the phone number (7 digits, with a dash): 555-1234 555-1234 is associated with Bob Bob's SSN is 000300021 Bob's salary is 55000 Sample run2: Enter the phone number (7 digits, with a dash): 675-4566 Couldn't find a name associated with that number. Sample run3: Enter the phone number (7 digits, with a dash): 000-2345 000-2345 is associated with John John's SSN is 000000004 John's salary is 65000 python languagearrow_forward3. Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. Use the numbers.txt file to test your program. (Hint: Open the file and read every string stored in it. Use a variable to keep a count of the number of lines that are read from the file.) Comment your source code and describe your code to someone who may be viewing it for the first time. PLACE SCREEN SHOTS OF THE PYTHON CODE AND ALL I/O BELOW. Please use Python Programmingarrow_forwardFor this program, assume you have an input file with several lines of text. Each line has a student's last name, followed by a space and then 4 numbers which represent his/her grades. Your program should read this input file and produce an output file with the same number of lines, each line showing the last name and the average of the student's scores. "grades.txt" is the file your program should read. "badformat.txt" is an example of a file that your program can't read, so a clear error message should be generated, as shown in the sample output. Your program must catch all exceptions. Your main method must NOT have a "throws" clause - it must catch all exceptions and dea' with them appropriately. Other methods may throw exceptions, as long as the main method catches them. I don't expect you to examine any filenames to make sure they're valid. Instead, you should use the filename the user gives you and try to open a file by that name. That will throw an exception if the filename is…arrow_forward
