- Question 1 of 1: Word Swap: Write a C++ program that will swap the words Caesar and Brutusin the file “source_file.txt”. You will need to load the file “source_file.txt” and finally write theupdated contents with the replaced words to the file “target_file.txt”.Successful operation should swap all occurrences of Caesar with Brutus and Brutus with Caesar.You can use functions from the cstring library. You are not allowed to use the string datatype.Please properly comment your code before submission.Question 1 of 1: Word Swap: Write a C++ program that will swap the words Caesar and Brutusin the file “source_file.txt”.

You are not allowed to use the string datatype. Once again, do not use string datatype.Please properly comment your code before submission.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…
- In C language, write the following two functions maintaining a database of entries of type song in a file. Here is the definition of the struct song: typedef struct { char* title; char* artist; int year; } song; int add_song(const char* file_name, const song s); 1. The function gets the name of a file, and a song. If the song is not in the file, the function adds it to the file and returns 1. Otherwise, the function does not modify the file and returns 0. song* find_song(const char* file_name, const char* title); 2. The function gets the name of a file and a title of a song. It searches the file for the song with the given title. If a song is found, it returns a pointer to the song with all the details. If not found, the function returns NULL. You may assume the song titles are unique. Additional instructions and hints: 1.

You may assign any file object. 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.
