Question

Vowel or Consonant?Write a program for Programming Exercise 4.10 on p.151 in the textbook.

Testing: Run the program for two vowels, two consonants, and two invalid characters.

Assume letters A/a , E/e , I/i , O/o , U/u as the vowels. Write a program that prompts the user to enter a letter and check whether the letter is a vowel or constant.

Answer 1

CODE IN C++:

#include <iostream>

using namespace std;

int main()
{
//declaring variables
char ch;
int i;
for(i=0;i<6;i++){
//taking input from the user
cout << "Enter a character:";
cin >> ch ;
//validating the character and displaying the result
if(ch=='a' || ch=='A' || ch=='e' || ch=='E' || ch=='i' || ch=='I' || ch=='o' || ch=='O' || ch=='u' || ch=='U'){
cout << "It is a vowel..."<<endl;
}
else if((ch>= 'a' && ch <= 'z')||(ch>= 'A' && ch <= 'Z')){
cout << "It is a constant..."<<endl;
}
else
cout << "It is an invalid character...."<<endl;
}

return 0;
}
OUTPUT:

input Enter a character:E It is a vowel... Enter a character:z It is a constant... Enter a character:% It is an invalid character. Enter a character:a It is a vowel... Enter a character:y It is a constant... Enter a character:7 It is an invalid character... ... Program finished with exit code o Press ENTER to exit console. |
