Question
Chapter 11, Problem 11.15E
Program Plan Intro
- ichar, line,ifilename,ofilename, i, choice, and x are input variables
- rfptr, wfptr are the file pointers to write the data.
Program description:
The main purpose of the program is to read and write the entered text line using file pointers either using the standard input and output or using the input and output file. The program first displays the menu to the user to select the choice which does not allow to enter invalid choice. It then uses the standard input and output or file names to get the data and display the data according to user choice with the help of file pointer.

Answer the given question with a proper explanation and step-by-step solution.
DO NOT WRITE MAIN! Only write the function. A 50% minimum deduction will be made if main is included. No libraries or comments should be specified.
(OP4) Write a function to prompt the user for the filename, open the file, and verify that it opened. If the file does not open, an error message should be printed and the user re-prompted. The function should use the string passed in for the prompt string. The function should not return until the file is open.
The function prototype:
void openInputFile( ifstream &, string );
ifstream& - the stream to be opened.
string - the prompt to be written out to the user. Use this string when prompting the user.

- can someone help me with this problem in C and explain how to do it step by steparrow_forwardProgram specifications: Write a function called rCopy that copies the entire contents of one file to another, but copies them over in reverse order. This function should take the names of the input and output files as strings. If either file does not open for any reason, the function should output an error message stating the name of the file that didn’t open and then return the value false. Otherwise, if both files open correctly, the function should return true once the reverse copy has been completed. For example, if a file named in.dat contains the following: A c d 87arc 65879 9 then after the function call: rCopy("in.dat", "out.dat") the file out.dat should contain the following: 9 97856 cra78 d c A You must solve this recursively!!

Each test case will start with an integer N. The next N lines will consist of a string S denoting the K-th name. After N lines of names will consists of a string F, a name that needs to be found. Format Output For each test case, print "Case #X: Y" where X is the number of test case starting from 1, and Y is the index where the name is.

- Use Scanner and File to read input from a file. Use PrintStream and File to write output to a file. Write and call methods that accept parameters and return values to manage information flow and add structure to programs. Follow prescribed conventions for spacing, indentation, naming, and comments. Notice that if an input file is not found, either for creating a mad-lib or viewing an existing one, the user is re-prompted. No re-prompting occurs for the output file. If the output file does not already exist, it is created. If it does already exist, its contents are overwritten. (These are the default behaviors in Java.) You may assume that the output file is not the same file as the input file. When you are viewing an existing mad lib story, you are simply reading and echoing its contents to the console. You do not need to do any kind of testing to make sure that the story came from a mad lib input file; just output the file's contents.
