Asked in companies
Given a string ‘STR’ which consists of uppercase and lowercase characters and spaces. Count the number of consonants in the string.
A consonant is an English alphabet character that is not vowel (a, e, i, o, and u). Examples of constants are b, c, d, f, etc.
Example :
Given string 'STR' : ‘Coding Ninjas’ there are 8 consonants i.e ‘C’,’d’,’n’,’g’,’N’,’n’,’j’,’s’, because these characters do not belong to set above mentioned set of vowels.
Problem approach
1. Get the string on which count has to be performed.
2. Run a loop from 0 to the length of the string.
3. Take a single character at a time and verify if they are a part of the group of vowels.
4. If the result is true, increase the count of vowels or else increment the count of consonants.
