istream member function__________ repositions the fileposition pointer in a file.
(FRP7) Write a function that reads data from a file. The file has already been opened and verified. The data should be saved in the array of type ship. The size of the array is passed in the int parameter and the number of records read is return in the last parameter, by reference. The file should be read until end of file has been reached or the array is full.
struct ship{ string shipCaptain; string shipName;
};
The function prototype isvoid readFile( ifstream&, ship[ ], int, int& );
ifstream - The already open file
ship[ ] - array of structs where the data from the file will be stored.
int - the size of the array.
int& - the number of records read from the file. This value is set by the function before returning
return- the number of records read from the file, returned by the function.
The amount of data in the file is unknown but there is no bad data. The file format is the shipsName followed by the shipsCaptiain .
Example:
MillenniumFalcon HansSolo
The __________ member function returns a file’s current write position.

- Array/File FunctionsWrite a function named arrayToFile. The function should accept three arguments:the name of a file, a pointer to an int array, and the size of the array. The functionshould open the specified file in binary mode, write the contents of the array to the file,and then close the file.Write another function named fileToArray. This function should accept three arguments: the name of a file, a pointer to an int array, and the size of the array. Thefunction should open the specified file in binary mode, read its contents into the array,and then close the file.Write a complete program that demonstrates these functions by using the arrayToFilefunction to write an array to a file, and then using the fileToArray function to readthe data from the same file. After the data are read from the file into the array, displaythe array’s contents on the screen.arrow_forwardWord List File WriterWrite a program that asks the user how many words they would like to write to a file, andthen asks the user to enter that many words, one at a time.

- Merge two files (1 point) Write a program that reads the content of two files “text1.txt” and “text2.txt" line by line and merges them into another file called “merge12.txt". You can safely assume that the input is valid. IN C PROGRAMMINGarrow_forwardplease code in python count_word: This function takes a filename and a keyword. Return the number of times the keywordoccurs in the file. Initialize a variable to keep track of the number of times the keyword appears.Traverse the file by line. Use the count method on each line to find the number of times the keywordappears in it and add that amount to the variablearrow_forwardFile Iteration: Introduction A text file is essentially a sequence of lines. Here is a typical coding pattern for processing each line of a file in turn: Open the file for reading. Use a for loop to iterate over the lines of text, executing a block of one or more statements to process each line. Close the file. Finish processing (print, return, etc.) if needed NOTE: You will need to use this pattern, or some variation of it, to solve the remaining coding problems in this assignment. As the following for loop iterates through each line of the file, the loop variable (`line`) represents the current line of the file as a string of characters. myFile = open("someTextFile.txt", "r") for line in myFile: do something on each iteration do a second thing on each iteration etc... myFile.close() PROBLEM: Read a string from standard input using python.
