Answer to Question #218074 in C for Hemambar

Question

given an input string Ayodhya your C program to count the number of vowels and consonants and print the frequency of occurrence of each vowel and consonant delete the vowels in the same input string and display the updated string

Sample input:

Enter the input string: Ayodhya

Sample output:

No of vowels:3

Frequency of occurrence:A-2;o-1

No of consonants:4

Frequency of occurrence:y-2;d-1;h-1
