string sentence;
int a = 0;
int num_vowels =0;
cout << "enter a sentence or phrase: " << endl;
getline(cin, sentence);
string *phrase = nullptr;
phrase = &sentence;
cout << "/......................../" << endl;
cout << "your sentence or phrase: " << *phrase << endl;
char choice;
do
{

cin >> choice;
switch(choice)

case 'A':

phrase++;
}
}

break;
}
}while(choice == 'D');
return 0;
}
void displaymenu()

cout << "Menu:" << endl;
cout << "Enter A: Count the number of vowels in the string: " << endl;
cout << "Enter B: Count the number of consonants in the string: " << endl;
cout << "Enter C: Count Both the vowels and consonants in the string: " << endl;
cout << "Enter D: Enter another string: " << endl;
cout << "Enter E: Exit the program: " << endl;
}
*************HELP WILL NOT RUN - GETS HUNG UP - WHAT AM I DOING WRONG THANKS C++ READ IN A STRING COUNT VOWELS HAVE TO USE POINTERS
Explanation / Answer
string sentence;
int a = 0;
int num_vowels =0;
cout << "enter a sentence or phrase: " << endl;
getline(cin, sentence);
string *phrase = nullptr;
phrase = &sentence;
cout << "/......................../" << endl;
cout << "your sentence or phrase: " << *phrase << endl;
Instead of above part try to use these:
char sentence[1000];
int a = 0;
int num_vowels =0;
cout << "enter a sentence or phrase: " << endl;
getline(cin, sentence);
char *phrase = nullptr;
phrase = sentence;
cout << "/......................../" << endl;
cout << "your sentence or phrase: " << *phrase << endl;
phrase = &sentence;
this statement is wrong. you are storing the address of string object into a string pointer.
