Write a program that prompts the user to input a sequence of characters and outp

Question

Write a program that prompts the user to input a sequence of characters and outputs A, E, I, O, U, and Y and the number of times each vowel appears in the input string.

A null-return function, inString, that prompts the user to input a sequence of characters.

A value-returning function, isVowel, that returns the value true if a given character is a vowel and otherwise returns false.

A null-return function, outVowels, that outputs a list of each vowel and the number of times that vowel appeared in the input sequance.

Explanation / Answer

#include <iostream>
#include<string.h>
#include <ctype.h>
using namespace std;

void inString(char *str){
   cout<<"Enter a string: ";
   cin.getline(str, 50);
   }
bool isVowel(char c){
   if(c=='a'||c=='A'||c=='e'||c=='E'||c=='i'||c=='I'||c=='o'||c=='O'||c=='u'||c=='U'||c=='y'||c=='Y') {
return true;
}
else {
return false;
}
}

void outVowels(int out[]){
   cout<<"Count for A: "<<out[0]<<endl;
   cout<<"Count for E: "<<out[1]<<endl;
   cout<<"Count for I: "<<out[2]<<endl;
   cout<<"Count for O: "<<out[3]<<endl;
   cout<<"Count for U: "<<out[4]<<endl;
   cout<<"Count for Y: "<<out[5]<<endl;
   }
  
int main() {
  
   char str[50]; // input array
   //taking user input
   inString(str);
  
   int length = strlen(str);
   int countVowel[6] = {0}; // vowel counter, A, E, I, O, U, Y
   for(int i=0; i<length; i++){
       if(isVowel(str[i])){
           char c = tolower(str[i]); // coverting into lower case
           // based on vowel, incrementing counter
           switch(c){
               case 'a' :
                   countVowel[0]++;
                   break;
               case 'e' :
                   countVowel[1]++;
                   break;
               case 'i' :
                   countVowel[2]++;
                   break;
               case 'o' :
                   countVowel[3]++;
                   break;
               case 'u' :
                   countVowel[4]++;
                   break;
               case 'y' :
                   countVowel[5]++;
               }
           }
       }
  
   //printing vowel count
   outVowels(countVowel);
  
  
return 0;
}

/*

output:

Enter a string: adadweewwdiwod wsxcscuwmfswy eedjwe
Count for A: 2
Count for E: 5
Count for I: 1
Count for O: 1
Count for U: 1
Count for Y: 1
