The letters a, e, i, o, and u are vowels. All the other letters are consonants. To check wheher the given character is a vowel or consonant we have to compare the given character with the letters a, e, i, o, u. If checking returns a true value then it is a vowel.
We are using fmt.println() function for printing the string to the output screen. Here we are showing how to check character is vowel or consonant in the Go language. Here variable chr is used to hold the read character. For reading the character create the reader using NewReader. Check the character read is a vowel or consonant by comparing the characters with vowels.
func (r *Reader) ReadByte() (byte, error)
ReadByte implements the io.ByteReader interface
Finally print the results. Given below are the steps which are used in the Go program.
STEP 1: Import the package fmt, bufio, os
STEP 2: Start function main()
STEP 3: Create a reader using NewReader as reader := bufio.NewReader(os.Stdin)
STEP 4: Read the character into variable chr as chr, _, _ := reader.ReadRune()
STEP 5: Check the character is vowel or consonant by comparing the characters with vowels
STEP 6: Use if statement for printing proper message
package main
import (
"bufio"
"fmt"
"os"
)
func main() {
reader := bufio.NewReader(os.Stdin)
fmt.Print("Enter the character = ")
chr, _ := reader.ReadByte()
if chr == 'a' || chr == 'e' || chr == 'i' || chr == 'o' || chr == 'u' ||
chr == 'A' || chr == 'E' || chr == 'I' || chr == 'O' || chr == 'U' {
fmt.Printf("%c is a VOWEL character\n", chr)
} else {
fmt.Printf("%c is a CONSONANT\n", chr)
}
}
Enter the character = e e is a VOWEL character Enter the character = c c is a CONSONANT
