WRITE IN C++ :

Enter a string through the keyboard (For end use Ctrl+A). The string should be copied into an output file text.txt. Then open an input file stream to read from the file text.txt. Each character that is a letter or a digit should be stored into an array text2[]. For checking use the functions (isalpha(char) and isdigit(char)). Print the array. Sort the array using all the four sorting algorithms: Selection Sort, Insertion Sort, Bubble Sort and Quicksort. While sorting count the number of steps needed to sort the array with the particular algorithm. Print each number on screen
