CPS 151/Fall 2011 Assignment 01 (Vectors of structs/Sorting/Graphic output) Assigned: August 29, 2011 Due: September 8, 2011 Do you know which letter is most frequent in typical English text? Which is the least frequent? In this assignment you will read some text from a file and count the number (the frequency) of each letter. The frequencies will be stored in a vector (of a structure). But to understand the basic ideas let us use an array of integers (size 26) first. Upper case and lower case letters will not be distinguished. Characters other than letters (such as digits, punctuations, other symbols) may be present. Those non-alphabetic characters will not be counted. Suppose we declare: int counters[26] = {0}; // initialize all counters to zeros What will be the contents of the array counters after the following text is processed? A quick brown fox jumped over the lazy dog. 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

This assignment is the beginning of a grading program, which we will continue to develop over some of the following assignments. The objective of the program is to input 3 test scores (in the range 0-100), calculate the average score, then determine the appropriate letter grade using the standard scale, A - 90% or above, ... F - below 60%. Input to the program: a) student's first name and last name (use C++ string class) b) 3 test scores (all int) Output from the program (all on one line, table format) a) student's name in (last, first) format (Calculated, not just displayed) b) 3 test scores (int) c) average (double) Show only 2 digits after decimal point d) letter grade (char)
