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++
// C++ program to remove vowels from a String #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 -= 2; } } return str; } // Driver Code int main() { string str = "GeeeksforGeeks - A Computer" " Science Portal for Geeks" ; cout << remVowel(str) << endl; return 0; } // This code is contributed by // sanjeev2552 |
Java
// Java program to remove vowels from a String import java.util.Arrays; import java.util.List; class Test { static String remVowel(String str) { Character vowels[] = { 'a' , 'e' , 'i' , 'o' , 'u' , 'A' , 'E' , 'I' , 'O' , 'U' }; List<Character> al = Arrays.asList(vowels); StringBuffer sb = new StringBuffer(str); for ( int i = 0 ; i < sb.length(); i++) { if (al.contains(sb.charAt(i))){ sb.replace(i, i+ 1 , "" ) ; i--; } } return sb.toString(); } // Driver method to test the above function public static void main(String[] args) { String str = "GeeeksforGeeks - A Computer Science Portal for Geeks" ; System.out.println(remVowel(str)); } } |
Python
# Python program to remove vowels from a string # Function to remove vowels def rem_vowel(string): vowels = ( 'a' , 'e' , 'i' , 'o' , 'u' ) for x in string.lower(): if x in vowels: string = string.replace(x, "") # Print string without vowels print (string) # Driver program string = "GeeksforGeeks - A Computer Science Portal for Geeks" rem_vowel(string) |
C#
// C# program to remove vowels from a String using System; using System.Text; using System.Linq; using System.Collections.Generic; public class Test { static String remVowel(String str) { char []vowels = { 'a' , 'e' , 'i' , 'o' , 'u' , 'A' , 'E' , 'I' , 'O' , 'U' }; List< char > al = vowels.OfType< char >().ToList();; StringBuilder sb = new StringBuilder(str); for ( int i = 0; i < sb.Length; i++) { if (al.Contains(sb[i])){ sb.Replace(sb[i].ToString(), "" ) ; i--; } } return sb.ToString(); } // Driver method to test the above function public static void Main() { String str = "GeeeksforGeeks - A Computer Science Portal for Geeks" ; Console.Write(remVowel(str)); } } //This code is contributed by Rajput-Ji |

We can improve the above solution by using Regular Expressions.
C++
// C++ program to remove vowels from a String #include <bits/stdc++.h> using namespace std; string remVowel(string str) { regex r( "[aeiouAEIOU]" ); return regex_replace(str, r, "" ); } // Driver Code int main() { string str = "GeeeksforGeeks - A Computer Science Portal for Geeks" ; cout << (remVowel(str)); return 0; } // This code is contributed by Arnab Kundu |
Java
// Java program to remove vowels from a String import java.util.Arrays; import java.util.List; class GFG { static String remVowel(String str) { return str.replaceAll( "[aeiouAEIOU]" , "" ); } // Driver Code public static void main(String[] args) { String str = "GeeeksforGeeks - A Computer Science Portal for Geeks" ; System.out.println(remVowel(str)); } } |
C#
// C# program to remove vowels from a String using System; using System.Text.RegularExpressions; class GFG { static String remVowel(String str) { str = Regex.Replace(str, "[aeiouAEIOU]" , "" ); return str; } // Driver code public static void Main() { String str = "GeeeksforGeeks - A Computer Science Portal for Geeks" ; Console.WriteLine(remVowel(str)); } } //This code is contributed by 29AjayKumar |
Python
# Python program to remove vowels from a string # Function to remove vowels # import the module for regular expression (re) import re def rem_vowel(string): return (re.sub( "[aeiouAEIOU]" ,"",string)) # Driver program string = "GeeksforGeeks - A Computer Science Portal for Geeks" print rem_vowel(string) |
Output:
GksfrGks - Cmptr Scnc Prtl fr Gks
