Asked in companies
You are given a string STR of length N. Your task is to remove all the vowels present in that string and print the modified string.
English alphabets ‘a’, ‘e’, ‘i’, ‘o’, ‘u’ are termed as vowels. All other alphabets are called consonants.
Note: You have to only remove vowels from the string. There will be no change in the relative position of all other alphabets.
For example:
(i) If the input string is 'CodeGeek', the output should be CdGk after removing ‘o’ and ‘e’.
(ii) If the input string is 'Odinson', the output should be 'dnsn' after removing ‘o’ and ‘i’.
Problem approach
Make array and use switch cases like
switch(ch)
{
case 'a':
case 'e':
case 'i':
case 'o':
case 'u':

case 'E':
case 'I':
case 'O':
case 'U':
return 1;
default:
return 0;
}
