Question

Please provide answer in the format that I provided, thank you

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.

You must insert the following comments at the beginning of your program and write our commands in the middle:

Write a C++ Program:

/*

// Name: Your Name

// ID: Your ID

// Purpose Statement:~~~

*/

#include <iostream>

#include <string>

using namespace std;

void removeVowels(string& str);

bool isVowel(char ch);

int main()

{

    string str;

    cout << "Enter a string: ";

    …

    …

         YOUR CODE HERE

    …

    …

return 0;

}

void removeVowels(string& str)

{

    int len = str.length();

    …

    …

         YOUR CODE HERE

    …

    …

}

bool isVowel(char ch)

{

    switch (ch)

    …

    …

         YOUR CODE HERE

    …

}

Answer 1

#include <iostream>

#include <string>

using namespace std;

void removeVowels(string &str);

bool isVowel(char ch);

int main()

{

    string str;

    cout << "Enter a string: ";

    // YOUR CODE HERE

    cin >> str;

    // remove all vowels

    removeVowels(str);

    cout << "String after removing vowels: " << str;

    return 0;

}

void removeVowels(string &str)

{

    int len = str.length();

    // YOUR CODE HERE

    int i = 0;

    while (i < len)

    {

        // if current char is vowel

        if (isVowel(str[i]))

        {

            // remove char

            str = str.substr(0, i) + str.substr(i + 1, len);

            len = str.length();

        }

        else

            i++;

    }

}

bool isVowel(char ch)

{

    switch (ch)

    {

        // YOUR CODE HERE

    case 'a':

    case 'A':

    case 'e':

    case 'E':

    case 'i':

    case 'I':

    case 'o':

    case 'O':

    case 'u':

    case 'U':

        return true;

    default:

        return false;

    }

}
