Below are some statements; the domain of each is the set of all integers. For symbolic statements, thenegation symbol (¬) must not apear in your answer. For English statements, don’t use “It is not the casethat” or just the word “not” to form the negation.For each one, state whether the statement is TRUE, FALSE, or CAN’T BE DETERMINED. For all that onesthat are TRUE or FALSE, state the negation:1.∃n(nis even)2.∀a∀b(3a≥2b)3.∀a∃b(ab= 1)
DO NOT USE AI! AI WILL NOT PASS THE TEST! Part I: Define a “word” as a maximal length sequence of alphanumerics. For example, in the line Hello, there! How are you? I am fine; how are you? My number is DE4-3656. the words are “hello”, “there”, “How”, “are”, “you”, “I” “am”, “fine”, “how”, “are”, “you”, “My”, “number”, “is”, “DE4”, and “3646”. Write a C program that reads lines from a file (you may assume it’s a text file) or files named on the command line, breaks them into words, stores the words in order (that is, ASCII order), and counts the number of times each word appears. Do not make any assumptions about the number of lines or words; but you may assume no word is over 256 characters long. When this is done, print the words and counts, as follows. This example is from the line above: 3646 (1) DE4 (1) Hello (1) How (1) I (1) My (1) am (1) are (2) fine (1) how (1) is (1) number (1) there (1) you (2) Call your file wordsort1.c.
