Question

Write a program that reads a string and outputs the number of times each lowercasevowel appears in it. Your program must contain a function with one of its parametersas a string variable and five other integerreference parameters with each one representing the number a particular vowelappears in the string. The program shouldrequest a string input from the user thendisplay the results of the function.

Function Definition : voidvowelCount(string wordInput, int& aCount, int& eCount, int& iCount, int& oCount, int& uCount) ;

The following is a sample output :

Enter a string for vowel analyzing : Programming

Number of a’s : 1

Number of e’s : 0

Number of i’s : 1

Number of o’s : 1

Number of u’s : 0

Explanation / Answer

#include<iostream>
#include<stdlib.h>
using namespace std;

// function to test lowerCase vowel
bool isLowerVowel(char c){
   if(c=='a'||c=='e'||c=='i'||c=='o'||c=='u') {
return true;
}
else {
return false;
}
}
// function to count vowel
void vowelCount(string wordInput, int& aCount, int& eCount, int& iCount, int& oCount, int& uCount){
   unsigned int i;
   for(i=0; i<wordInput.size(); i++){
       int c = wordInput.at(i);
       if(isLowerVowel(c)){
           switch(c){
               case 'a': aCount++; break;
               case 'e': eCount++; break;
               case 'i': iCount++; break;
               case 'o': oCount++; break;
               case 'u': uCount++; break;
               }
           }
       }
   }
  
int main(){
   string input;
   int aCount=0, eCount=0, iCount=0, oCount=0, uCount=0;
  
   //user input
   cout<<"Enter a string: ";
   cin>>input;
  
   vowelCount(input, aCount, eCount, iCount, oCount, uCount);
  
   //printing
   cout<<"Number of a’s : "<<aCount<<endl;
   cout<<"Number of e’s : "<<eCount<<endl;
   cout<<"Number of i’s : "<<iCount<<endl;
   cout<<"Number of o’s : "<<oCount<<endl;
   cout<<"Number of u’s : "<<uCount<<endl;
  
   return 0;
   }

/*

Output:

Enter a string: Programming
Number of a’s : 1
Number of e’s : 0
Number of i’s : 1
Number of o’s : 1
Number of u’s : 0
