Finally, print the counts of vowels, consonants, and whitespaces.
Code
#include <bits/stdc++.h>
using namespace std;

// Function to count vowels, consonants, and white spaces in a string
int solve(string str, int length) {
    // Variables to store counts
    int vowels = 0, consonants = 0, whitespaces = 0;

    // Convert the string to lowercase
    for (int i = 0; i < length; i++) {
        str[i] = towlower(str[i]);
    }

    // Traverse the string
    for (int i = 0; i < length; i++) {
        // Check for vowels
        if (str[i] == 'a' || str[i] == 'e' || str[i] == 'i' || str[i] == 'o' || str[i] == 'u')
            vowels++;
        // Check for consonants
        else if (str[i] >= 'a' && str[i] <= 'z')
            consonants++;
        // Check for white spaces
        else if (str[i] == ' ')
            whitespaces++;
    }

    // Print the results
    cout << "Vowels: " << vowels << "\n";
    cout << "Consonants: " << consonants << "\n";
    cout << "White Spaces: " << whitespaces << "\n";
}

int main() {
    // Input string
    string str = "Take u forward is Awesome";

    // Get the length of the string
    int length = str.length();

    // Call the function
    solve(str, length);

    return 0;
