In java create a function that writes student name surname and id to a text file and call the function (registerstd) in main function. the function must accept the arguments name , surname and ID
Step by step
Solved in 2 steps with 2 images
- In java create a function searchstd() that reads a search record from a text file file.txt when the function is called in mainWith your knowledge in file systems write a javaprograms the can be used to: Rename a file in a directoryIn Java, the File class is used to represent the data in a directory entry. Write a program that uses the File class to print all the attributes of a file.
- In python, rite a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet... File name: file_path2 Lorem ipsum dolor sit amet... ... Test this function in a new program.Create a JAVA program that will overload a function named substring. The function will ask the user to enter the index range of the substring inclusive. Using the function defined the program will display the whole string value, the substring given the start index, and the substring given the start and last index. EXPECETED OUTPUT:The following project should be done in C++ language: Write a function (module) that reads the contents of a file named Char.txt (you will have to create this file on notepad or any other text editor and write a sentence of your choice. Your sentence should include upper case, lower case, and numbers. Keep in mind you need to submit this file as well) and determine the following: The number of uppercase letters in the file . The number of lowercase letters in the file The number of digits in the file The total number of characters in your sentence. Upon finishing the task, program will ask the user if they would like to read the same file again and the program will re-start (you need to utilize a loop to do so) should the user prompt the program with 'Y'. Prompts and Output Labels. There are no prompts-- nothing is read from standard keyboard, just from the file Character.txt. Each of the numbers calculated is displayed on a separate line on standard output, preceded by the following…
- Exercise 2:Write a Java program that allows the user to specify a file name on the command line and prints the number of characters, words, lines, average number of words per line, and average number of characters per word in that file. If the user does not specify any file name, then prompt the user for the name.In C write a program that takes a file name and two strings as command line arguments, and writes the longer of the two strings to the file with the given name. If the given strings are the same length, write the first string given to the file. If the user does not provide the correct number of command line arguments, print an error message and exit the program with a non-zero exit code.Write a function void saveByDept(char *fileName, char *deptName , student allStudents[], int size) that will save the information of all students who belong to the department with name pointed to by deptNameinto a text file. The name of the file is given as an input parameter, fileName
- Part 1: Write a C/C++ language program that creates an array of 10,000 random unsigned integers in the range 1 to 1,000,000. These integers are then stored in a text file called numbers.txt Part 2: Write a C/C++ language program that reads the file numbers.txt and checks each number for being a prime number. Only the prime numbers from these are then written to a text file prime.txt. Part 3: Modify the program of part 2 so that it takes an input argument num_jobs with a value between 1 and 8. E.g. if num_jobs is 3, it splits into 3 parallel processes using fork() function, and each process then calculates prime numbers from a subset of the input data. Together these 3 jobs find prime numbers from all the 10,000 input integers. The overall parent process then combines the results from its children into a single file prime.txt Part 4: Calculate the times taken by running the program of part 3, and make a table where the time taken for calculation is given for each value of num_jobs from…In Java A comma separated value (.csv) file has been included to be used for this program. Each line contains two values, a name and a number separated by a comma (except the first line, which contains the titles for the value types). The name is that of a writer and the number refers to the number of works the writer has written. Ex. Jane Austen,6. Each line is an entry and each entry number can be updated by identifying the associated name. Once complete, the following program opens data file allWorks.csv and asks if the user wants to update entries or add new entries. All entries are stored in an array while being read in and updated. The program then writes the array to the file, overwriting the original contents. The following TODO sections must be completed. Open allWorks.csv for reading/input. Locate an entry to be updated by name (use the Java String indexOf() method) Add a new entry if the name isn't found in the file (give the entry a new number) Open file allWorks.csv for…Write a menu driven C++ program to do the following: 1. Read Employees information from a data file: Name, Hrs work, rate of pay 2. Write the following data to an output text file. Name, Hrs work, rate of pay and Gross pay and net pay (tax 21%) 3. Print employees checks with net pay. Must use Classes, Functions, Advance Files IO, pointers, arrays and C++ STL.
