Write a program that will sequentially list numbers from 0 to 50, changing its color depending on the size of the number, for example, for numbers from 0 to 10 it will be green, 11 to 22 red and 23 to 35 blue, etc. Limit the screen output speed to about 1 character / second. In order to change colors, you must first use the GetStdHandle function to get a handle to the console, which is similar to getting a file pointer before working with a file. It is done e.g. as follows: HANDLE hConsole; hConsole = GetStdHandle (STD_OUTPUT_HANDLE); The above functions are defined in windows.h Tip 2: Write a utility to find out the colors corresponding to all combinations from 0 to 255. Tip 3: Instructions and sample program for working with time. C language plz with explanation of codes. thanks

Modify java code for Hw5 (stock,each csv file has headings: Date,Open,High,Low,Close, Adj Close,Volume) to count and print the number of days there is gain (increase from open to close price) of 2% or more of stock price. Also count and print the number of days the High is 30% bigger than Low. Also, find and print the average volume for the trading days where there is gain. Make sure each print occupies a single line, and all lines are lined up such that the label for each information requested is left aligned, and the decimal points are all aligned. import java.util.*; import java.io.*; public class StockData { public static double average(ArrayList<Double> prices) { double total = 0; double average; for (int i = 0; i < prices.size(); i++) { total = total + prices.get(i); } if (prices.size() > 0) { average = total / prices.size(); return average; } else { return 0; } } public static double min(ArrayList<Double>prices) { double min = prices.get(0); for (int i = 1; i…

Write a program that receives a coded message file(Lab3ExtraCreditCT.txt) from your local espionage agent and decodes it into a file using standard English. The problem is your agent forgot to tell you the key used to decode the message. Fortunately, this is a simple substitution code consistently using 1 alphanumeric character to represent another, this is case sensitive. All other characters are not substituted, so a space will always be a space, a – will always be a –, a @ will always be a @, etcetera. You may use the following table to help you, it contains the most common letters used in the English language in descending order.

In each case, determine and fix the problem, remove all syntax and coding errors, and run the program to ensure it works properly.
