|| with characters

[gregv21]

what is a another whey i could
do this

                                                  // dosen't allow or  
    if ( Letter = 'a' || Letter = 'A' || Letter = 'E' || Letter = 'e' || Letter = 'I' || Letter = 'i' || Letter = 'O' || Letter = 'o' || Letter = 'U' || Letter = 'u')
      {
                cout << " This is a vowel " << endl;
                
                }else{
                      
                      cout << " This letter is a consonant " << endl;
                      
                      }

switch(Letter)
{
    case 'a':case'A':case'e':case'E':case'i':case'I':case'o':case'O':case'u':case'U':
    cout << "This is a vowel"<< endl;
    break;
    default:
    cout<< "This letter is a consonant" << endl;
}

You can also do like this:
int i,check;
char al,vow[10]={'A','a','E','e','I','i','O','o','U','u'};
cout<<"Enter an alphabet:";
cin>>al;
for(i=0;i<10;i++)
{
if(al==vow[i])
{
check=1;
break;
}
else
check=0;
}
if(check==1)cout<<"\nThis letter is a vowel.";
else cout<<"\nThis letter is a consonant.";

Here's another way:

  static string vowels( "aeiouAEIOU" );
  // ... 
  cout << "This letter is a " <<
     ( vowels.find( Letter ) == vowels.npos ?
     "consonant" : "vowel" ) << endl;

I suggest using tolower to avoid checking both upper and lower case letters, e.g:

bool isvowel(int c) {
  c = std::tolower(c);
  return (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u');
}

int main() {
  //...
  if (isvowel(c)) {
    cout << "This is a vowel" << endl;
  } else if (std::isalpha(c)) {
    cout << "This is a consonant" << endl;
  } else {
    cout << "This is not a letter" << endl;
  }
}

My teacher says that this is easy I don't think so.

The ancient Egyptians wrote in hieroglyphics, in which vowels sounds are not represented, only consonants. Is written English generally understandable without vowels? To experiment, write a function isvowel( ) that tests whether or not a character is a vowel. Write a function in a program that reads the standard input file (keyboard) and write to the standard output file (screen), deleting all vowels.

I am sorry, I would have to agree with your teacher regarding this problem. You have been given a few good options on here showing how you can solve this problem very trivially.

rserrano, here is a program skeleton to get you started.

#include <iostream>   // For access to cout, cin, endl
#include <string>        // For access to string class

using namespace std;  // To avoid having to prefix std:: onto cout, cin, etc...

bool isvowel( char ch ) {
   // Lots of examples above
}

string read_input() {
   // Have this function read from standard input a string (using cin)
   // and return the string read.
}

void output( string const& s ) {
   // Pass in the string you read from read_input.
   // For each character in the string:
   //    if character is a consonant (ie, call isvowel)
   //       output the character to standard output (using cout)
}

int main() {
   // Get input (ie, call read_input )
   // Output answer (ie, call output)
   return 0;
}
