Question

(b) You will write a program that will do the following: prompt the user enter characters from the keyboard, you will read the characters until reading the letter ‘Q’ You will compute statistics concerning the type of characters entered. In this lab we will use a while loop. We will read characters from stdin until we read the character ‘Q’.

Example input mJ0*5/]+x1@3qcxQ

The ‘Q’ should be included when computing the statistics properties of the input. Since characters are integers you will determine the average character (average when one looks at the character as an integer (its ASCII value). To achieve this you will need to compute the sum of the ASCII values of the characters. We are interested in determining the following statistics

1.The number of lowercase alphabetical characters

2.The number of even digits ‘0’, ‘2’, ‘4’, ‘6’, ‘8’

3.The total number of characters inputted (include ‘Q’)

4.The number of line feeds (ASCII value of 10)

5.The average character (here we treat the characters as an integer based on their ASCII values)

6.The average alphabetical character that is read (include the ‘Q’)

Output each in a formatted manner (in your output describe what the output is,

for example The number of even digits is 5

THIS CODE HAS TO BE WRITTEN USING THE C PROGRAMMING LANGUAGE.
