Given a string, remove the vowels from the string and print the string without vowels.
Examples:
Input : welcome to geeksforgeeks
Output : wlcm t gksfrgks
Input : what is your name ?
Output : wht s yr nm ?
A loop is designed that goes through a list composed of the characters of that string, removes the vowels and then joins them.
C++14
#include <bits/stdc++.h>
using namespace std;
string remVowel(string str)
{
vector<char> vowels = {'a', 'e', 'i', 'o', 'u',
'A', 'E', 'I', 'O', 'U'};
for (int i = 0; i < str.length(); i++)
{
if (find(vowels.begin(), vowels.end(),
str[i]) != vowels.end())
{
str = str.replace(i, 1, "");
i -= 1;
}
}
return str;
}
int main()
{
string str = "GeeeksforGeeks - A Computer"
" Science Portal for Geeks";
cout << remVowel(str) << endl;
return 0;
}

We can improve the above solution by using Regular Expressions.
C++
#include <bits/stdc++.h>
using namespace std;
string remVowel(string str)
{
regex r("[aeiouAEIOU]");
return regex_replace(str, r, "");
}
int main()
{
string str = "GeeeksforGeeks - A Computer Science Portal for Geeks";
cout << (remVowel(str));
return 0;
}

Java
import java.util.Arrays;
import java.util.List;
class GFG
{
static String remVowel(String str)
{
return str.replaceAll("[aeiouAEIOU]", "");
}
public static void main(String[] args)
{
String str = "GeeeksforGeeks - A Computer Science Portal for Geeks";
System.out.println(remVowel(str));
}
}

Python3
import re
def rem_vowel(string):
return (re.sub("[aeiouAEIOU]","",string))
string = "GeeksforGeeks - A Computer Science Portal for Geeks"
print(rem_vowel(string))

C#
using System;
using System.Text.RegularExpressions;
class GFG
{
static String remVowel(String str)
{
str = Regex.Replace(str, "[aeiouAEIOU]", "");
return str;
}
public static void Main()
{
String str = "GeeeksforGeeks - A Computer Science Portal for Geeks";
Console.WriteLine(remVowel(str));
}
}
