- 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. IN C PLEASEWrite a function named file_sum that takes as a parameter the name of a text file that contains a list of numbers, one to a line, like this: 23.77 116 94 -12.8 0 14.999 The function should sum the values in the file and write the sum (just that number) to a text file named sum.txt.given a text file (data1.txt) that consists of different garbage strings.1.Create a new file, from data1.txt, which contains all the strings from theprevious file with the following constraints:-No special characters or digits must be in the new string-No repetition of letters in the new string• Save the newly generated text-file as data2.txtThe following example in table 1 shows what your output file should contain.data1.txt data2.txtf5@p fpp&ott6 potInstructions:Create a class cleanFile to read in data1.txtClean the data inside the files following the rules in the above exampleWrite the cleaned data into data2.txt
- 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, fileNameWrite a function that takes two lists of integers X and Y as input, and computes and writes a table into a file named "question2.txt" as follows: - On each line the computations for an X,Y pair is given Each such possible pair must exist in the file in the same order of values in X and Y Next on each line, you provide X+Y, X*Y and X^2 + Y^2, all separated by a comma (and no spaces or other characters must exist). Note that X^2 represents "square of X". For example, given X = [1,3] and Y=[-1,1,0], "question2.txt" should contain the following table: question2.txt 1,-1,0,-1,2 1,1,2,1,2 1,0,1,0,1 3,-1,2,-3,10 3,1,4,3,10 3,0,3,0,9 As you can see, the first line is computed for X=1, Y=-1. The second line is built for X=1, Y=1; and the third line is for X=1, Y=0. It goes on like this, until X=3, Y=0. def op2file(X, Y): in python3. Write a function which reads an already existing file “File1.txt” and write digits (0-9) in to a new text file “mynumber.txt” and non digits into a file “Text.txt”.in c++
