The image appears to show a multiple-choice question interface with several options. Each option contains a set of numerical values, possibly related to floating-point representations in computer science or mathematics.### Transcription of Choices:1. **Option 1:** - 123.457 - 00000000000123.457 - 123.4566999999999999 2. **Option 2:** - 123.457 - 123.4570000000000000 - 123.45673. **Option 3:** - 123.457 - 00000000000123.457 - 123.4566999999999998### Explanation:Each option presents a series of numbers that are often equal when considering floating-point precision in programming. The numbers highlight how different decimal representations can be visually distinct but computationally equivalent under certain conditions. This is important when considering rounding errors and precision in software development. There are no graphs or diagrams to explain further. **Question:**What are the contents of the "Output.txt" file when you execute the following code snippet?```cppint main(){ double salary = 123.4567; ofstream out_file; out_file.open("Output.txt"); out_file << left << setw(18) << salary << endl; out_file << setfill('0') << setw(18) << salary << endl; out_file << setprecision(18) << salary << endl; return 0;}```**Options:**1. 123.457 00000000000123.457 123.4566999999999992. 123.457 123.457000000000000 123.45673. 123.457 00000000000123.457 123.456699999999998**Explanation:**The code snippet is a simple C++ program which writes to a file "Output.txt." It uses various manipulations to format the output:- `setw(18)`: Sets the width of the output to 18 characters.- `left`: Left aligns the output within the given width.- `setfill('0')`: Fills the empty spaces with zeros.- `setprecision(18)`: Sets the precision of the floating-point output to 18 decimal places.The expected behavior for each line is as follows:1. The first line left aligns the number with a total width of 18 spaces, so it will be `123.457` (further decimal values are truncated to three decimal points by default), padded with spaces. 2. The second line uses `setfill('0')` with `setw(18)`, leading to zeros filling the width before the number, resulting in `00000000000123.457`.3. The third line sets the precision to 18, printing the full double precision, which may result in small discrepancies due to the nature of floating-point representation. The output will likely be something like `123.45670000000000001`, closely matching `123.456699999999998` due to floating-point arithmetic precision.Therefore, the correct answer is option **3**.

There are a couple of issues in your code. It seems there's a typo in the variable name for the…

Filename: runlength_decoder.py Starter code for data: hw4data.py Download hw4data.py Download hw4data.pyYou must provide a function named decode() that takes a list of RLE-encoded values as its single parameter, and returns a list containing the decoded values with the “runs” expanded. If we were to use Python annotations, the function signature would look similar to this:def decode(data : list) -> list: Run-length encoding (RLE) is a simple, “lossless” compression scheme in which “runs” of data. The same value in consecutive data elements are stored as a single occurrence of the data value, and a count of occurrences for the run. For example, using Python lists, the initial list: [‘P’,‘P’,‘P’,‘P’,‘P’,‘Y’,‘Y’,‘Y’,‘P’,‘G’,‘G’] would be encoded as: ['P', 5, 'Y', 3, ‘P’, 1, ‘G’, 2] So, instead of using 11 “units” of space (if we consider the space for a character/int 1 unit), we only use 8 “units”. In this small example, we don’t achieve much of a savings (and indeed the…
Write a function that reads all the numbers from a file into an array. The file is already open and there is no bad data in the file. The data is one number per line and an unknown number of lines of data. The function should read data until either end of file is detected or the array is full. Prototype void readData( ifstream& iFile, double numbers[ ], int size, int& count); iFile - already open ifstream numbers[ ] - array to store data size - the size of the array. count - the number of values read and must be set by the function before returning.
