Question

I'm having trouble to write a value-returning function, isVowel, that returns the value true if a given character is a vowel and otherwise returns false. Can I get help with this?

Answer 1

#include<iostream>

using namespace std;

int isVowel(string s)

{

 int f=0;

 char ch;

 for(int i=0;i<s.length();i++)

 {

 ch=toupper(s[i]);

 if(ch=='A' || ch=='E' || ch=='I' || ch=='O' || ch=='U')

 {

 f=f+1;

 }

 }

 return f;

}

int main()

{

 string s;

 cout<<"Enter a string ";

 cin>>s;

 cout<<"There are "<<isVowel(s)<<" vowels in this sentence.";

}

Answer 2

//Code.cpp

#include<iostream>

using namespace std;

bool isVowel(char ch){
   if(ch == 'a' || ch == 'e' || ch == 'i' || ch == 'o' || ch == 'u' || ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U'){
       return true;
   }
   return false;
}

int main(){
   //In c we have to represent the string as array of characters
   char string[100];
   char ch;
   cout<<"Input string: ";
   cin>>ch;
   if(isVowel(ch)==1){
       cout<<ch<<" is a vowel"<<endl;
   }
   else{
       cout<<ch<<" is NOT a vowel"<<endl;
   }
   return 0;
}
