In this example, you will ask a user to enter an Alphabet and check whether the Alphabet entered by the user is a vowel or consonant.
In the alphabet, a, e, i, o, and u are vowels and the rest are consonants.
#include<iostream>
using namespace std;
int main() {
char c;
cout << "Enter an Alphabet: ";
cin >> c;
if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' ||
c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U') {
cout << "\n " << c << " is a Vowel";
} else {
cout << "\n" << c << " is a consonant";
}
return 0;
}
Enter an Alphabet: A A is a Vowel
Enter an Alphabet: d d is a consonant
This program is a solution for when user input doesn't belong to a vowel or consonant.
#include<iostream>
using namespace std;
int main() {
char c;
cout << "Enter an Alphabet: ";
cin >> c;
if (c >= 'a' && c <= 'z' || c >= 'A' && c <= 'Z') {
if (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u' || c == 'A' || c == 'E' ||
c == 'I' || c == 'O' || c == 'U')
cout << "\n " << c << " is a Vowel";
else
cout << "\n" << c << " is a consonant";
} else {
cout << "\n" << c << " is a not belong to vowels or consonant";
}
return 0;
}
Enter an Alphabet: @ @ is a not belong to vowels or consonant
Time Complexity: O(1)
