In this tutorial we are going to learn writing program in C to check a given character is vowel or consonant. To write the complete program we will use if else statement to check input character is equal to vowel or consonant.
Before start writing C Program, lets understand about vowel and consonant.
What is Vowel and Consonant?
In English alphabets a, e, i, o, u characters are known as alphabets. And Rest of the characters are known as Consonant.
Vowel : a, e, i, o, u
Consonant : b, c, d
How our vowel and consonant program will work?
- Our program will take one character as an input.
- If character will match with Vowels like any of a, b, c, d, e, then print character is vowel.
- And in the rest case it will print consonant.
- Here is one edge case like if someone has inserted any special characters, then our program will print neither vowel nor consonant.
C Program to Check a given character is Vowel or Consonant
#include <stdio.h>
int main()
{
char ch;
printf("C program to check given character is vowel or consonant \n");
printf("Please enter a character\n");
scanf("%c", &ch);
if ((ch >= 'a' && ch <= 'z') || (ch >= 'A' &&ch <= 'Z')) {
if (ch=='a' || ch=='A' || ch=='e' || ch=='E' || ch=='i' || ch=='I'
|| ch=='o' || ch=='O' || ch== 'u' || ch=='U')
printf("Given Character %c is a vowel.\n", ch);
else
printf("Given Character %c is a consonant.\n", ch);
}
else
printf("Given Character %c is neither a vowel nor a consonant.\n", ch);
return 0;
}
Output 1:
C program to check given character is vowel or consonant
Please enter a character
t
Given Character t is a consonant.
C Program to check vowel and consonant using isAlpha() method
isAlpha() method is available in ctype.h header file to check whether a given character is alphabets or not. It will help to check if there is some special character given in input, print given character is neither vowel nor consonant.
#include <stdio.h>
#include <ctype.h>
int main() {
char ch;
printf("=== C program to check given character is vowel or consonant === \n");
printf("Please enter a character: ");
scanf("%c", &ch);
if (!isalpha(ch))
printf("Given Character %c is neither a vowel nor a consonant.\n", ch);
else if ((ch=='a' || ch=='A' || ch=='e' || ch=='E' || ch=='i' || ch=='I'
|| ch=='o' || ch=='O' || ch== 'u' || ch=='U'))
printf("Given Character %c is a vowel.", ch);
else
printf("Given Character %c is a consonant.", ch);
return 0;
}
Output
=== C program to check given character is vowel or consonant ===
Please enter a character: g
Given Character g is a consonant.
