Given the following readLineSync() function (from dart:io library) to read input from the command line or terminal: import 'dart:io'; void main () { stdout.write ("Input:"); var input = stdin.readLineSync () ; stdout.write (input + "\n"); Need to get input from the user. The input can be any size with unlimited values but only with integer and double data types. For example: Input: 21, 23, 12, 45, 39, 40 Input: 2.2, 45, 3.6, 6.6, 70 Then split the input into a list by using the .split() function. Once have the list, perform mathematical operations on the values. For example: Input: 21, 23, 12, 45, 39, 40 Summation: 180 Average: 30 Division: 0.00000108 Subtraction: -138 Multiplication: 406879200||

Implement a simple version of the linux cat command in C++. Use the system calls open(), get() and close(). cat - reads a file as specified by the user and prints its contents. A typical usage is as follows: If from my terminal y run ./cat main.cpp the contents of main.cpp. will be printed. Your program cat can be invoked with one or more files on the command line; it should just print out each file in turn. Example: [terminal]$ ./cat main.cpp main2.cpp #include <iostream>using namespace std;int main(){cout << "Hello, World!"; return 0;}#include <iostream>using namespace std;int main(){cout << "Programming is great fun!";return 0;} As you can see content of main.cpp was printed first and the content of main2.cpp

Design and implement a program that reads an integer value (let's say x) as a command line argument. Further, the program reads a series of 'x' integer values from the user and prints their average. Read each input value as a String, and then attempt to convert it to an integer. If this process throws an exception (meaning that the input is not a valid number), print the appropriate error message and prompt for the number again. Continue reading values until 'x' valid integers have been entered. Hint: Think of all possible errors that this process could cause, and incorporate appropriate exception handlers in your programs. Note: You cannot use the root/general exception class 'Exception'
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
