Store the text in a string. Output the string.Ex:Enter a sample text:We'll continue our quest in space.There will be more shuttle flights and more shuttle crews and,yes,more volunteers, more civilians,more teachers in space. Nothing ends here;our hopes andour journeys continue !You entered: We'll continue our quest in space.There will be more shuttle flights and moreshuttle crews and,yes,more volunteers, more civilians,more teachers in space. Nothing endshere;our hopes and our journeys continue!(2) Implement the PrintMenu() function to print the following command menu.Ex:MENUc - Number of non-whitespace charactersNumber of wordsfFind textReplace all !'ss - Shorten spacesrQuit(3) Implement the ExecuteMenu() function that takes 2 parameters: a character representing the user's choice and the user providedsample text. ExecuteMenu() performs the menu options, according to the user's choice, by calling the appropriate functions describedbelow.(4) In the main() function, call PrintMenu() and prompt for the user's choice of menu options for analyzing/editing the string. Each option isrepresented by a single character.If an invalid character is entered, continue to prompt for a valid choice. When a valid option is entered, execute the option by callingExecuteMenu(). Then, print the menu, and prompt for a new option. Continue until the user enters q. Hint: Implement Quit beforeimplementing other options.Ex:MENUc - Number of non-whitespace charactersw - Number of wordsf - Find textr - Replace all !'ss - Shorten spacesq - QuitChoose an option:
