6. Write a program in C to check whether a character is a vowel or a consonant using the Switch Case statement .

Objective:
The goal of this program is to determine if a given character is a vowel or a consonant using the Switch Case statement in C programming. By using the Switch Case statement, the program can effectively handle different scenarios and provide the correct output based on the input character.
Agenda:
1. Create a variable to hold the input character.
2. Ask the user to input a character.
3. Use the Switch Case statement to check if the input character is a vowel or a consonant.
4. Show the user the result based on how the character is classified.
Purpose:
This program aims to showcase how the Switch Case statement is used in C programming to distinguish between vowels and consonants. By sorting characters into vowels and consonants, the program helps in grasping fundamental concepts of control flow in programming and enhances problem-solving abilities. Additionally, this program lays the groundwork for more intricate decision-making processes in programming.
Real-Life Applications:
1. Text processing software can utilize this program to recognize and manipulate vowels and consonants in textual information.
2. Language analysis tools can apply this program to examine and categorize characters in linguistic data.
3. Educational programs can integrate this program to educate students about vowels and consonants in an engaging manner.
4. Data validation systems can employ this program to validate input characters and ensure they meet specific criteria based on being a vowel or a consonant.
6. Write a program in C to check whether a character is a vowel or a consonant using the Switch Case statement .

/* a program in C that check whether a character is
a vowel or a consonant using the Switch Case statement. */
#include <stdio.h>
int main()
{
char ch;
printf("\n Enter any character: ");
scanf("%c", &ch);
switch(ch)
{
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':
case 'A':
case 'E':
case 'I':
case 'O':
case 'U':
printf("\n%c is a vowel.", ch);
break;
default:
printf("\n %c is a consonant.", ch);
}
return 0;
}

Output:
Enter any character:
U
U is a vowel.

a program in C programming langguage to check whether a character is a vowel or a consonant using the Switch Case statement.

Explanation
1. We start by including the stdio.h header file required for input and output operations.
2. We declare a variable ch of type char to store the input character.
3. We ask the user to enter characters using printf() and read the input characters using scanf().
4. We use a switch to check the entered character against the lowercase and uppercase vowels "a", "e", "i", "o", "u".
5. If the input character matches any vowel, we print that it is a vowel with printf().
6. If the entered character does not match any vowel, we use the default case to print that it is a consonant.
7. Finally, return 0 indicates successful execution of the program.
