Answer to Question #296941 in C++ for Andrew

Question

Write a program that first reads an integer for the array size,

then reads characters into the array, and displays the consonants (i.e., a character

is displayed only if it a consonant). (Hint: Read a character and store it to an array

if it is not a vowel. If the character is a vowel, discard it. After the input, the array

contains only the consonants.)

Answer 1

#include <iostream>




bool is_consonant(const char * c)
{
    char consonant[] = "BCDFGHJKLMNPQRSTVWXYZbcdfghjklmnpqrstvwxyz";
    if (strpbrk(c, consonant) != NULL)
    {
        return 1;
    }
    else
    {
        return 0;
    }
}




int main()
{
    char* arr = nullptr;
    int arr_size = 0;


    int size = 0;
    std::cout << "Enter size of array : ";
    std::cin >> size;
    for (int i = 0; i < size; i++)
    {
        std::cout << "Enter symbol number " << i + 1 << " : ";
        char tmp[2];
        std::cin >> tmp;
        if (is_consonant(tmp))
        {
            char* tmp_arr = new char[arr_size + 1];
            for (int j = 0; j < arr_size; j++)
            {
                tmp_arr[j] = arr[j];
            }
            tmp_arr[arr_size] = tmp[0];


            delete[]arr;
            arr = tmp_arr;
            arr_size++;
        } 
    }
    for (int i = 0; i < arr_size; i++)
    {
        std::cout << arr[i] << "\t";
    }
    std::cout << std::endl;




    system("pause");
    return 0;
}
