Question

Take the following C++ code and add to it the following:

Write a program that reads a string and outputs the number of times each lowercase vowel appears in it. Your program must contain a function with one of its parameters as a char variable, and if the character is a vowel, it increments that vowel's count.

#include<iostream>

#include<string>

using namespace std;

int countVowel(char, char);

int main(void)
{
string str1;
int countA = 0;
int countE = 0;
int countI = 0;
int countO = 0;
int countU = 0;
  
cout<<"ENter a word to count vowels: ";
cin>>str1;
  
for(int i = 0; i<str1.length (); i++)
{
countA = countA + countVowel (str1.at (i), 'a');
countE = countE + countVowel (str1.at(i), 'e');
countI = countI + countVowel (str1.at (i), 'i');
countO = countO + countVowel (str1.at (i), 'o');
countU = countU + countVowel (str1.at (i), 'u');
}
cout<<"The vowel A appears: ";
<<countA<<end1;
}
}

#include <iostream>
#include <string>

using namespace std;

int countVowel(char, char);

int main(void)
{
    string str1;
    int countA = 0;
    int countE = 0;
    int countI = 0;
    int countO = 0;
    int countU = 0;

    cout << "ENter a word to count vowels: ";
    cin >> str1;

    for (unsigned int i = 0; i < str1.length(); i++) {
        countA = countA + countVowel(str1.at(i), 'a');
        countE = countE + countVowel(str1.at(i), 'e');
        countI = countI + countVowel(str1.at(i), 'i');
        countO = countO + countVowel(str1.at(i), 'o');
        countU = countU + countVowel(str1.at(i), 'u');
    }
    cout << "The vowel a appears: " << countA << endl;
    cout << "The vowel e appears: " << countE << endl;
    cout << "The vowel i appears: " << countI << endl;
    cout << "The vowel o appears: " << countO << endl;
    cout << "The vowel u appears: " << countU << endl;
}

int countVowel(char c1, char c2) {
    return c1 == c2;
}

Answer 2

Write a program that prompts the user to input a string. The program then uses the function substr to remove all the vowels from the string. For example, if str = "There", then after removing all the vowels, str = "Thr". After removing all the vowels, output the string. Your program must contain a function to remove all the vowels and a function to determine whether a character is a vowel
