Write a C++ Program to Check Whether a character is Vowel or Consonant.

Answer

Solution:
/* C++ Program to Check Whether a character is Vowel or Consonant */
#include
using namespace std;
int main()
{
char c;
int isLowercaseVowel, isUppercaseVowel;
cout << "Enter any character to check :: ";
cin >> c;
// evaluates to 1 (true) if c is a lowercase vowel
isLowercaseVowel = (c == 'a' || c == 'e' || c == 'i' || c == 'o' || c == 'u');
// evaluates to 1 (true) if c is an uppercase vowel
isUppercaseVowel = (c == 'A' || c == 'E' || c == 'I' || c == 'O' || c == 'U');
// evaluates to 1 (true) if either isLowercaseVowel or isUppercaseVowel is true
if (isLowercaseVowel || isUppercaseVowel)
{
cout<<"
The Entered Character [ "< ";
}
else
{
cout<<"
The Entered Character [ "< ";
}
return 0;
}
Output:
/* C++ Program to Check Whether a character is Vowel or Consonant */
Enter any character to check :: u
The Entered Character [ u ] is a Vowel.
Process returned 0

{
int x,y,sum;
cout<<"Enter first number :: ";
cin>>x;
cout<<"
Enter second number :: ";
cin>>y;
sum=x+y;
cout<<"
Sum of two numbers [ "< ";
return 0;
}

Output:
/* C++ Program to find Addition of Two Numbers */
Enter first number :: 12
