C++ program to check whether an Alphabet is Vowel or Consonant

In this article, we will discuss the concept of C++ program to check whether an Alphabet is Vowel or Consonant

In this post, we are going to learn how to write a program to check whether given English alphabet is Vowel or Consonant using various ways in C++ language

C++ Code to check whether Vowel or consonant

Code to check given Alphabet is Vowel or consonant using If else

In this code, we are going to learn how to write a program to check the given English alphabet is Vowel or not using if-else and or operator in C++ language

Program 1

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
    char ch;//Declare character variable ch

    cout<<"Enter an Alphabet: \n";
    //Ask input an Alphabet
    cin>>ch;
//Reading the Alphabet input from user
          //Checking both of lower case and upper case vowels using || (or) operator
          if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I'||ch=='o'||ch=='O'||ch=='u'||ch=='U')
{//check vowel using if condition
  cout<<ch<<" is a vowel";//Display vowels
}
else{
  cout<<ch<<" is a consonant";//display consonant

}
getch();
    return 0;

}

When the above code is executed, it produces the following result

Case 1

Enter an Alphabet:
A
A is a Vowel

Case 2

Enter an Alphabet:
z
z is a Consonant

Code to check given Alphabet is Vowel or consonant using Nested If

In this code, we are going to learn how to write a program to check the given English alphabet is Vowel or consonant using Nested if-else and or operator in C++ language

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    char ch;//Declare a character variable
    cout<<"Enter a character\n";//Ask input from the user
    cin>>ch;//Rea in put from the user
    if((ch>='A' && ch<='Z')||(ch>='a' && ch<='z')){ //outer if use to check Alphabets

  if(ch=='a'||ch=='A'||ch=='e'||ch=='E'||ch=='i'||ch=='I'||ch=='o'||ch=='O'||ch=='u'||ch=='U')
{//inner if for checks vowels
  cout<<ch<<" is an vowel";//display vowels
}
else{//display consonant
cout<<ch<<" is a consonant";
}

}
else{
cout<<ch<<" is neither a vowel nor a consonant";
}

getch();
    return 0;
}

When the above code is executed, it produces the following result

Case 1

Enter an Alphabet:
I
I is a Vowel

Case 2

Enter an Alphabet:
b
b is a Consonant

Code to check the Alphabet is Vowel or consonant using Ascii

In this code, we are going to learn how to check the given English alphabet is Vowel or consonant using Ascii value in C++ language

Program 3

#include <iostream>
#include <conio.h>
using namespace std;
int main()
{
    char ch;//Declare character variable ch

    cout<<"Enter an Alphabet: \n";
    //Ask input an Alphabet
    cin>>ch;
//Reading the Alphabet input from user
          //Checking both of lower case and upper case using || (or) operator
          if(ch==97||ch==101||ch==105||ch==111||ch==117||ch==65||ch==69||ch==73||ch==79||ch==85)
{//check vowel using if condition
  cout<<ch<<" is an vowel";//Display vowels
}
else{
  cout<<ch<<" is a consonant";//display consonant

}
getch();
    return 0;

}

When the above code is executed, it produces the following result

Case 1

Enter an Alphabet:
I
I is a Vowel

Case 2

Enter an Alphabet:
b
b is a Consonant

Code to check the Alphabet is Vowel or consonant using switch

In this code, we are going to learn how to check the given English alphabet is Vowel or consonant using switch statements in C++ language

Program 4

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
  char ch;
    cout<<"Enter any Alphabets: ";
    cin>>ch;

    switch(ch){
case 'a':
    cout<<'a'<<" is Vowel";
    break;

    case 'e':
   cout<<'e'<< " is Vowel";
    break;

     case 'i':
   cout<<'i'<< " is Vowel";
    break;

     case 'o':
   cout<<'o'<< " is Vowel";
    break;

     case 'u':
   cout<<'u'<< " is Vowel";
    break;

case 'A':
    cout<<'A'<< " is Vowel";
    break;

    case 'E':
   cout<<'E'<< " is Vowel";
    break;

     case 'I':
   cout<<'T'<< " is Vowel";
    break;

     case 'O':
   cout<<'O'<< " is Vowel";
    break;

     case 'U':
   cout<<'U'<< " is Vowel";
    break;

    default:
        cout<<ch<<" is consonant";
    break;
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following result

Case 1
