Step by step
Solved in 2 steps
- It's not apparent what will happen if an incorrectly coded software is executed. What will happen after the frmProgram code has been written? Is it possible to display the event handler for the command button? The sentence "Unload Me" has a function, but what is it? What does an executable file do?Explain in your own words when writing data to a file, what is the difference between the print and the println methods? Explain in your own words what does the Scanner class’s hasNext method return when the end of the file has been reached?Explain in your own words: a.) When writing data to a file, what is the difference between the print and the println methods? b.) What does the Scanner class’s hasNext method return when the end of the file has been reached?
- You'll learn what a file extension is and which programs create them here. Give concrete instances to back up your claims.It is not apparent what will happen if an incorrectly coded software is executed. What will happen when I type in the code for frmProgram? The event handler for the command button may be displayed? What, exactly, does the Unload Me statement serve? If a file is executable, what are its goals?Should we make an exception to the procedure, and if so, why?
- How do you pass the file name as a command-line argument? Show that in the code with the screenshot of the output of the text file being read in the terminal.Your ReadRoomFile program reads a room file. Is it possible to tell how many rooms are in the file from the file size? Explain why or why not?How would you rewrite the syntax to read in the file if it was tab-delimited (for example, if it has a .dat extension)? Copy & paste the code below and replace the blanks [1] , [2] , etc, with the missing syntax you would use to complete the import. Assume that you've already set your working directory to the folder containing the file. [1] <- [2]([3], header = [4]).
- First, take your program and add one more feature: at the end, just before you close the file, write the word “END” all by itself on a line. Run that program once to create a file of items with “END”. Instead of reading from cin and writing to a file, you read from your file and write to cout. The only tricky part is deciding when to stop reading. In your previous code, you stopped reading when the user said they didn’t want to continue. For the new code, keep reading until you read “END” for the name of the produce. You can use “==” on strings, so if (product name == ”END”) will tell you that you can stop reading. My code: #include<iostream>#include<string.h>#include<fstream>using namespace std; int main(){ string filename; cout<<"Enter the name of the file to store the information"<<endl; getline(cin,filename); ofstream fileptr(filename.c_str()); if(!fileptr.is_open()) { cout<<"Couldn't open a file"<<endl; }…How do change the code so that one or more command-line arguments are accepted as well as outputting a message when no command-line arguments are provided by the user? The expected behavior is that the program should print the files, in order, to standard output, effectively concatenating the contents of the supplied files.What would happen if faulty software was run? After writing frmProgram code, what happens? Can the command button event handler be displayed? The Unload Me statement serves what? Why are executable files necessary?
