Write the difference between structure and union. Also discuss a scenario where using aunion will be more appropriate with explanation

Repeat Programming Exercise 3 by declaring numl, num2, and num3, and average of type double. Store 75.35 into numl, -35.56 into num2, and 15.76 into num3.Write a BNF description of the precedence and associativity rules defined below. Assume the only operands are the names a,b,c,d, and e. Precedence Highest *, / +, - - (unary) Lowest =, /= Associativity Left to right
- show a parse tree and a leftmost derivation for each of the following statements:For the following pairs of expressions, find a unifier for each pair if a unifier exists. If a unifierdoes not exist, explain why.(a) p(X,Y) and p(a,Z)(b) p(X,X) and p(a,b)(c) f(X,Y) and f(a,g(a))(d) q(X) and ¬q(a)C++ question Question 2: syllable count Problem statement In English, a syllableLinks to an external site. is a unit of pronunciation having one vowel sound (a, e, i, o, u). For example the word innocent has 3 syllables as we can break it into 3 sounds like in·no·cent. As a general rule of thumb, the Oxford English Dictionary says, “with most adjectives and adverbs of more than one syllable, and with all those of more than two syllables,” “the normal mode” of forming the comparative and superlative is by using “more” and “most”. For example we say more or most innocent rather than using innocenter or innocentest. Imagine you are an engineer of a team developing English grammar checker. Your task is to write a function named count_syllables to count number of syllables in a given English word of all lower case letters.
