there! I have this code in C++ and for some reason it produces these empty spaces between the lines of the letters still to be guessed? How do I fix it? #include #include using namespace std; const int MAX_GUESSES = 10; // Prints empty lines at the beginning of execution void clean_screen(); // Checks if all the letters include in the list of guessed letters bool is_word_already_guessed(string secret, string guessed); // Prints string using '_' in the places of letters not guessed void print_game_status(string secret, string guessed); int main() { string secret_word = ""; cout << "Give a word to be guessed: "; getline(cin, secret_word); clean_screen(); string guessed_letters = ""; int guesses_used = 0; while ( not is_word_already_guessed(secret_word, guessed_letters) and guesses_used < MAX_GUESSES ) { cout << endl << "Game status: "; print_game_status(secret_word, guessed_letters); if ( guessed_letters.size() > 0 ) { cout << "You have used " << guesses_used << " guesses!"<< endl << "You have guessed letters: " << guessed_letters << endl; } string guess = ""; cout << "Guess a letter: "; getline(cin, guess); if ( guess.size() != 1 ) { cout << "You failed: give exactly one letter!" << endl; continue; } else if ( guessed_letters.find(guess) != string::npos ) { cout << "You failed: you had already guessed the letter " << guess << "!" << endl; continue; } guessed_letters += guess; if ( secret_word.find(guess) == string::npos ) { cout << "Guessed letter does not include the word!" << endl; } ++guesses_used; } if ( not is_word_already_guessed(secret_word, guessed_letters) ) { cout << endl << "Guesses expired!" << endl; cout << "The correct word was: " << secret_word << endl; } else { cout << endl << "Right guess.

Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
