ifstream inFile("inventory.dat"); Can I understand this code creat a file named inventory and open (or write) something in the file?

2. Suppose that you are implementing a program to write a string "CSE SS0" in a binary file. Java provides you three different methods – writeBytes(String), writeChars(String), and writeUTF(String). How many bytes will be written by each of those method for the give string? Which method did you find as the most efficient?

C++ Write a program that reads (arbitrarily many) integers from a file named by the user and outputs the 3rd smallest integer read.  The file integers are in arbitrary order, and the file may have a different number of  integers on different lines.   You should not store many numbers all at once to do this!  You'll only need a few integer variables, one for the smallest thus far, one for the second smallest thus far and one for the third smallest thus far.  I strongly suggest you work out you code in pseudocode first.

Please help me debug my C++ Program. Leave as much original source code as possible just show corrections.   int main() {string fileName{};cout<< "What is the file name";cin >> fileName; ifstream inFile;infile.open(fileName); ofstream outfile;outfile.open(Ch3_Ex5Output.dat"); string lastName{};string firstName{};double currentSalary{0};double percentIncrease{0}; while(!inFile.eof()){inFile >> lastName >> firstName >> currentSalary >> percentIncrease; currentSalary += currentSalary * percentIncrease / 100; outfile<< firstName << " " << lastName << " " << currentSalary << endl; } infile.close(); outfile.close(); return 0; }
