Given a string “str”, the task is to duplicate vowels in this string.
Examples:
Input: str = "geeks" Output: geeeeks Input: str = "java" Output: jaavaa
Approach: Iterate the string using a loop. Check if the character is a vowel and duplicate it. Return
then print the resultant string.
Below is the implementation of the above approach:
C++
// C++ program for printing string // with duplicate vowels #include <bits/stdc++.h> using namespace std; // Function to check for the Vowel bool isVowel(char ch) { ch = toupper(ch); return (ch == 'A' || ch == 'E' || ch == 'I' || ch == 'O' || ch == 'U'); } // Function to get the resultant string // with vowels duplicated string duplicateVowels(string str) { int t = str.length(); // Another string to store // the resultant string string res = ""; // Loop to check for each character for (int i = 0; i < t; i++) { if (isVowel(str[i])) { res += str[i]; } res += str[i]; } return res; } // Driver Code int main() { string str = "helloworld"; // Print the original string cout << "Original String: " << str << endl; string res = duplicateVowels(str); // Print the resultant string cout << "String with Vowels duplicated: " << res << endl; } |
