(M. Sc.) CSC 801 PROGRAMMING LANGUAGE PARADIGMNS TERM PAPER SUBMITTED TO THE DEPARTMENT OF COMPUTER SCIENCE, UNIVERSITY OF LAGOS, AKOKA June, 2015. ABSTRACT This is a survey on the programming languages paradigm: Imperative, Scripting, logic, Functional, object oriented and Markup. Our survey work involves a comparative study of these six programming languages with respect to the above programming paradigm using the following criteria: secure programming practices, web application development,

Name: Josiah Morales Title: Amines Introduction: Amines are organic compounds containing nitrogen containing the functional group R−NH2. Amines are capable of forming hydrogen bonds and small amines are quite soluble in water. Amines are one of the primary functional groups in amino acids, and are often found as part of compounds that are physiologically active or used in medications. In this experiment, the identity of an unknown amine or amine salt had to be determined using Solubility testing

A miniscale diels-alder reaction was performed between the conjugated diene 2,3dimethyl-1,3 butadiene and a substituted alkene such as maleic anhydride in order to produce a substituted cyclohexane. The substituted cyclohexane produced was 4,5-dimethyl-4-cyclohexene-cis-1,2-dicarboxylic acid anhydride. A diels- alder reaction does not have an intermediate state, meaning that bond breaking and bond making occurs at the same time. Heat needs to be applied in order for the reaction to occur and it is

lacks side effects (or more specifically, is referentially transparent) A language with a clear correspondence to mathematical logic. Declarative programming is an umbrella term that includes a number of better-known programming paradigms (i.e. Functional + Logic Programming). Referential transparency means that an expression (such as a function call) can be replaced with its value; this requires that the expression has no side effects and is pure (always returns the same results on the same
