Write a function called process_data that meets the specification written below. Your method should be programmed defensively and should handle any of the possible errors that may arise from reading from a file printing an appropriate error message to the screen. Function: process_data This function reads data from a file and calculates the sum of all of the values found in the file. It does this by reading the file one line at a time and if the line contains a single number, it adds that value to the sum; otherwise the line is ignored. Params: filename -- a string that contains the name of a file Returns: The sum of all of the numbers in the file, or 0 if there are no numbers

Write a function called countWord(). It takes 2 parameters: The name of a text file(e.g. gettysburg.txt) and a word to be searched within that file. Your code should returnthe number of times the given word appears in the file.>>> countWord('gettysburg.txt', 'people')3

Write a function definition called, sigma, that takes an input file reference and two integer references as its parameters. The function should read the numbers from a file, calculate their total value (cumulative sum), find the largest, and smallest numbers in the file. The function should return the cumulative sum, the largest, and the smallest values to the calling function. Note: the function reads the entire file.
Question 55 Write a function that takes two parameters, a file name to create and an integer. The function should write all the even numbers between 0 and the integer to the file name passed in. The numbers should be all on one line of the file For example: write_evens("even_file.txt",20) This should create a file called even_file.txt that contains 0 2 4 6 8 10 12 14 16 18 20 Full explain this question and text typing work only thanks

Write a program whose main function is merely a collection of variable declarations and function calls. This program reads a text and outputs the letters, together with their counts, as explained below in the function printResult. (There can be no global variables! All information must be passed in and out of the functions. Use a structure to store the information.) Your program must consist of at least the following functions: Function openFile: Opens the input and output files. You must pass the file streams as parameters (by reference, of course). If the file does not exist, the program should print an appropriate message ("The input file does not exist.") and exit. The program must ask the user for the names of the input and output files. Function count: Counts every occurrence of capital letters A-Z and small letters a-z in the text file opened in the function openFile. This information must go into an array of structures. The array must be passed as a parameter, and the file…
Write a function called max_age(inFile, outFile, breed), that takes three strings as input parameters. The function reads all the data from the inFile (1st input parameter) and writes data to the outFile (2nd input parameter) as described below. Each line in the input file represents a pet record and has the following format. name, breed, age where name and breed are strings, and age is an integer value. Your function must find the oldest pet of a given breed (3rd input parameter) from the inFile and write the following information to the outFile. breed, total records of this breed name of the oldest pet, age of the oldest pet Note that outFile must only have these two lines of information. Suppose, inFile contains the following data: shadow, longhair, 3 poshi, bangal, 5 mikus, longhair, 4 tigger, calico, 9 If you call this function with breed = "longhair", then the following must be written in the outFile: longhair, 2 mikus, 4 Your function must return…

My Question starts here In the code linked Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file if a command line argument is given to the program (using your readEmpFromFile function you just wrote). Question ends here To make it easier so that you do not have to go through the entire code I'm going to put writeEmpToFile function right here after the question but if you still need to look at the full code to get an understanding of what you are working with its linked at the bottom void writeEmpToFile(Employee *emp, FILE…
Write a void function that will merge the contents of two text files containing the chemical elements into a single binary file. The function's parameters will be three file pointers; each text file will contain an integer atomic number followed by the element name, chemical symbol and atomic weight. Here are two sample lines: 11 Sodium Na 22.9920 Calcium Ca 40.08 The function can assume that one file does not two copies of the same elements and that the binary output file should have the same property.

Modify sh.c so that all commands entered by the user are appended to a file called commands.txt. The commands should be logged into the file before they are If txt does not exist, your program is responsible for creating it. Create a program called frequency.c. This program will read from commands.txt and display the number of times each command occurred. You are not allowed to request more memory than necessary during the calculation of the frequency. You need to implement and apply the following two utility functions: int num_elements(char* str); This function counts the number of characters in string str. void append(char** str, char c); This function appends char c to string str. It might need to resize str. The output should be in the form <command>:<occurrence> for each unique command in commands.txt. You also need to provide a readme file (in PDF format) to (i) answer the questions in Part A; (ii) explain the major points of your program. Sample run: $…

Operations and required featurest that you need to cover inyour program are following:• Add: This function adds a new person to json file. You need to get inputs from userand adds the new one into json file.• Display: This function displays all people in your json file.• Search: This function let you search with the user id.• Create Password: This function will create a random password for the user and usermay choose the length of the password. Password may include numbers andcharacters.• Exceptions: You need to handle exceptions as well. You should at least handle 3 ofexceptional cases. For the case that file can not be found, It is mandatory to catch theexception.
