Program to accept a Strings which contains all the Vowels
• Last Updated : 21 May, 2021

Given a string S, the task is to check and accept the given string if it contains all vowels i.e. ‘a’, ‘e’, ‘i’.’o’, ‘u’ or ‘A’, ‘E’, ‘I’, ‘O’, ‘U’.
Examples:

Input: S = “GeeksforGeeks”
Output: Not Accepted
Since S does not contain vowels a, i and u
Input: S = “ABeeIghiObhkUul”
Output: Accepted
Since S contains all vowels a, e, i, o and u

Approach:

• Hashing can be used to solve this problem easily. For this, a hash data structure needs to be created of size 5 such that the index 0, 1, 2, 3, and 4 represent the vowels a, e, i, o, and u.
• Create a Boolean Array, as the hash data structure, to check that all vowels are present or not in the string.
• Iterate over the string character by character and if the character is vowel then mark that vowel present in the Boolean Array
• After the Iteration of the string, check that is there any vowel which is not present in the boolean array.

Below is the implementation of the above approach:

## C++

 `// C++ implementation to check that``// a string contains all vowels` `#include ``using` `namespace` `std;` `// Function to to check that``// a string contains all vowels``int` `checkIfAllVowels(string str)``{` `    ``// Hash Array of size 5``    ``// such that the index 0, 1, 2, 3 and 4``    ``// represent the vowels a, e, i, o and u``    ``int` `hash = { 0 };` `    ``// Loop the string to mark the vowels``    ``// which are present``    ``for` `(``int` `i = 0; i < str.length(); i++) {` `        ``if` `(str[i] == ``'A'` `|| str[i] == ``'a'``)``            ``hash = 1;` `        ``else` `if` `(str[i] == ``'E'` `|| str[i] == ``'e'``)``            ``hash = 1;` `        ``else` `if` `(str[i] == ``'I'` `|| str[i] == ``'i'``)``            ``hash = 1;` `        ``else` `if` `(str[i] == ``'O'` `|| str[i] == ``'o'``)``            ``hash = 1;` `        ``else` `if` `(str[i] == ``'U'` `|| str[i] == ``'u'``)``            ``hash = 1;``    ``}` `    ``// Loop to check if there is any vowel``    ``// which is not present in the string``    ``for` `(``int` `i = 0; i < 5; i++) {``        ``if` `(hash[i] == 0) {``            ``return` `1;``        ``}``    ``}``    ``return` `0;``}` `// Function to to check that``// a string contains all vowels``int` `checkIfAllVowelsArePresent(string str)``{` `    ``if` `(checkIfAllVowels(str))``        ``cout << ``"Not Accepted\n"``;``    ``else``        ``cout << ``"Accepted\n"``;``}` `// Driver Code``int` `main()``{``    ``string str = ``"aeioubc"``;``    ``checkIfAllVowelsArePresent(str);` `    ``return` `0;``}`
