/* Program 1:

Write a C program that reads array of characters up to 15 elements. 
The program does the following: (1)finds and prints the actual 
length of the input (2) finds the frequencies of letters a, b and c (3)
finds the most frequent and the least frequent among characters a, b and c
    Compile and run your program
