Below is a C++ hangman game code,i am not sure how to modify it so that to pass the stupid tests on hypergrade like shown #include #include #include

using namespace std;

/// @brief Puts dashes in place of alphabetic characters in the phrase. /// @param phrase the phrase to be solved /// @return the phrase with all alphabetic characters converted to dashes string setupUnsolved(string phrase) { string unsolved = ""; int len = phrase.length();

for (int i = 0; i

return unsolved; }

/// @brief Replaces the dashes with the guessed character. /// @param phrase the phrase to be solved /// @param unsolved the phrase with dashes for all unsolved characters /// @param guess the char containing the current guessed character /// @return the new unsolved string with dashes replaced by new guess string updateUnsolved(string phrase, string unsolved, char guess) { string newUnsolved = unsolved; int len = phrase.length();

for (int i = 0; i

return newUnsolved; }

/// @brief Gets valid guess as input. /// /// A guess is taken as input as a character. It is valid if /// 1) it is an alphabetic character; and /// 2) the character has not already been guessed /// /// @param prevGuesses the string containing all characters guessed so far /// @return a valid guess and only a valid guess as a character char getGuess(string prevGuesses) { int len = prevGuesses.length(); char guess; cin >> guess; guess = tolower(guess);

int flag = 1; if (!isalpha(guess)) flag = 0;

for (int i = 0; i

if (flag) return guess; else return '#'; }

int main() { string phrase; cout

string unsolved = setupUnsolved(phrase); cout

int guessLeft = 7; int finish = 0; char guess; string prevGuesses = "";

while (guessLeft > 0 && !finish) { cout

while (guess == '#') { cout

string temp = unsolved; unsolved = updateUnsolved(phrase, unsolved, guess); if (temp == unsolved) { guessLeft--; } prevGuesses += guess; cout

if (unsolved == phrase) { finish = 1; } }

cout

if (finish) cout

} This is what it looks like when my code gets into hypergrade

and this is what hypergrade asks for

basically it only accepts lowercase letter guesses, please help
