Question

c program where the user enters a list of

letter (ignoring lower case and upper case, 'a' is the same as 'A')and

the program returns the number of occurences of that letter.for

example, if the user types in GaaAAbbssaBgggGG the programreturns







a = 5







b = 3







s = 2







g = 6















the

next part of the program we have to sort the letters by themost

frequently occuring to the least frequently occuring. which, inthis

case, would give us:







gabs















for the sorting we have to use the following functiondeclaration:







void sort(int frequency[], char letters[], int left, intright);

Explanation / Answer
