C++ Programming

3. Please submit the following files: email2-algorithm.txt email2.cpp and email2.txt (program saved as text file)

1. modify email1-algorithm.txt to create email2-algorithm.txt to prompt the user for the input and output filenames, open and read the input file, and output to the console the lines that contain the character @. If a line contains the character @ more than once, it should be output once for each. If a line contains no @ at all, it should NOT be output. 2. Write email2.cpp from email2-algorithm.txt The program should prompt the user for the input and output filenames, open and read the input file, and output to the console the lines that contain the character @. If a line contains the character @ more than once, it should be output once for each. If a line contains no @ at all, it should NOT be output. Use an EOF loop to process the input file. Adapt the for-loop from the nsaEncoder.cpp program, to traverse each line that you input. In the loop, test each character in the line to see if equals the character @, and if it does, output the line to the console, and continue through the rest of the line, looking for more @'s. Here are some guidelines: If you open the output file, you are not doing this right. If you do not have nested loops, you are not doing this right. If you do not process the text a line at a time, you are not doing this right. If you do not using the for-loop from the nsaEncoder.cpp, you are not doing this right. If you use pointers or char arrays or C-style coding or C-library functions, except for ones demonstrated in our textbook, you are not doing this right. If you do not create your own input files with which to test your program, you are not doing this right. If you do not test your program with the ten .txt files provided in the project writeup, you are not doing this right. Compile and run the program. Submit the source file to the class website for credit. Program I/O. The program should prompt the user for the input and output filenames, and then output the input file's lines to the console with the character @, once per occurance. There is NO file output in this version. Example. Your program's console I/O should look something like this, (excluding your program introduction information): Enter input filename [default: fileContainingEmails.txt]: x.txt Enter output filename [default: x.txt]: y.txt input filename: x.txt output filename: y.txt press any key to continue:
