Program to remove vowels from a String

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.

We can improve the above solution by using Regular Expressions.
