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.

8.7 LAB: File name change A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. Ex: If the input of the program is: ParkPhotos.txt and the contents of ParkPhotos.txt are: Acadia2003_photo.jpg AmericanSamoa1989_photo.jpg BlackCanyonoftheGunnison1983_photo.jpg CarlsbadCaverns2010_photo.jpg CraterLake1996_photo.jpg GrandCanyon1996_photo.jpg IndianaDunes1987_photo.jpg LakeClark2009_photo.jpg…

Implement the following functions. Each function deals with null terminated C-Style strings. You can assume that any char array passed into the functions will contain null terminated data. Place all of the functions in a single file and then (in the same file) create a main() function that tests the functions thoroughly. Here are the functions: This function finds the last index where the target char can be found in the string. it returns -1 if the target char does not appear in the string. The function should be case sensitive (so 'b' is not a match for 'B'). int lastIndexOf(const char* inString, char target) This function alters any string that is passed in. It should reverse the string. If "flower" gets passed in it should be reversed in place to "rewolf". For efficiency, this must be done "in place", i.e., without creating a second array. void reverse(char* inString) This function finds all instances of the char 'target' in the string and replace them with…
The following Python code is a partially written function that attempts to read a file's contents into a dictionary. Fill in the missing code in the make_dictionary function. You do not need to copy any of the existing code. Just write the code that would go in place of "YOUR CODE HERE". def make_dictionary(filename):'''Function -- make_dictionaryCreates a dictionary from a file's contents. Each line in the file is split into a list at commas.If, after splitting, the list contains exactly 2 parts,the first item is added to the dictionary as a keyand the second item is the value.

Use C++. This lab should provide you with practice in stream formatting. classes are pretty much useless here. (There also may be opportunities for file handling!) Write a program that creates a table for the user's choice of basic math operations (+, -, *, /, and %). These operations will all be performed in an integer-only way. (Modulo doesn't work with decimals anyway... And you're going to have enough trouble lining up the table without dealing with decimal places on division!) The user should also be allowed to choose the size of the table (it will, of course, be square: 4x4, 5x5, etc.). You may limit the maximum size of the table, for formatting purposes. Make sure your table is neat and lines up nicely (see the examples below). Columns should all be of equal width. This should be the minimum width necessary to hold the largestanswer for the table's operation. (Be careful! This may be a negative value!) Note that, if each column is as small as possible, you can fit more of them…
. In c write a program that:a) takes an input file name from the command line;b) opens that file if possible;c) declares a C struct with three variables; these will have data types thatcorrespond to the data types read from the file (i.e. string, int, float);d) declares an array of C structs (i.e. the same struct type declared in point c);e) reads a record from the file and stores the values read into the appropriatestruct variable at the appropriate array index (for that record);f) continues reading each record into a struct (as in point 1e), and stores eachstruct containing the 3 values into the array of structs declared in point d;g) closes the file when all records have been read.Note that your program should print an error message in the event that the filecannot be opened successfully.
