CSE1PES: PROGRAMMING FOR ENGINEERS AND SCIENTISTS ASSIGNMENT 2 2020 (10%) Assignment developed by Matthew Felicetti 2020 TOOLS • Unix server through Putty for compiling and testing • Notepad ++ for writing solutions • LMS for submission SUBMISSION The task requires ONE submission: • The code for assignment 2 o Submitted as a .c file in the normal assignment submission portal. o (Do not submit the executable.) o There is NO late submissions for this assignment. o Requests for extensions, need to be sent by email: ▪ Doctors certificates need to cover a period greater than 3 days, and not submitted less than 3 days before the assignment is due. ▪ Special consideration will be rejected due to the assignment being worth less than 15%. o Filenames must be in the format ▪ _assign2.c DUE DATE AND TIME 23RD of May 2020, 11PM There is NO late submissions for this assignment. No assignment will be accepted after the due date, without a legitimate extension granted by the subject coordinator before the due date. ACADEMIC INTEGRITY Plagiarism is the submission of somebody else’s work in a manner that gives the impression that the work is your own. For individual assignments, plagiarism includes the case where two or more students work collaboratively on the assignment. The School of Engineering and Mathematics treats plagiarism very seriously. When it is detected, penalties are strictly imposed. http://www.latrobe.edu.au/students/academic-integrity http://www.latrobe.edu.au/students/academic-integrity PRELIMINARY TASK – DOWNLOAD THE CODE PACKAGE On Unix, create a directory named 'assignment_2' if you have not done so already (see lab0) Change into this directory Copy the files using the command below: cp ~csilib/cse1pes/students/assign2/* . replace with your student number What is cp? cp is the copy command in Unix The first argument is the source and the second the destination cp source destination Why is the destination a . If you put a . as the second argument, it will take the name of the file/s you are copying Make sure you have your version. Even though they look like others, they are NOT the same. Every student’s template contains various unique signatures. Using someone else's version or code from another version will result in a mark of 0 BACKGROUND BACKGROUND - TASK You are tasked with writing one c program related to chemical compounds and elements. In the task, given a set of compounds, two reactants and two products, and you will determine if the reactants and products are balanced. BACKGROUND – CHEMICAL ELEMENTS A chemical element is a type of atom that makes up all the ordinary matter in the universe, and is defined by the number of protons in its nucleus. Currently there are 118 known elements. These 118 can be represented on the periodic table of chemical elements as shown below: BACKGROUND – ATOMIC NUMBERS AND ELEMENT SYMBOLS The elements are all given names but are often represented as a series of letters (element symbol), starting with an Upper-case letter and following with zero, one or two lower case letters. These can be seen on the periodic table as shown below. Periodic Table Source: LeVanHan Creative Commons Element Name Element Symbol Beryllium Source: LeVanHan Creative Commons BACKGROUND – CHEMICAL COMPOUNDS A chemical compound or molecule is collection of atoms of more than one chemical element held together by chemical bonds. A common example of this is pure water, which is made up of two Hydrogen atoms and one Oxygen atom that are chemically bound. BACKGROUND – CHEMICAL FORMULA (MOLECULAR FORMULA) A chemical formula lists the elements and the proportion of atoms per element using element symbols. More specifically the chemical formula written as a molecular formula includes the exact number of atoms per element using element symbols. This is done by listing the symbols and a subscript to indicate the number of atoms for a particular atom (with no subscript indicating one). Example: ?2? Looking at our periodic table we can see the symbol H stands for Hydrogen, and O for oxygen. The subscript 2, indicates that there are two Hydrogen atoms and one Oxygen atom. BACKGROUND – CHEMICAL REACTION A chemical reaction is a process where one or more compounds/elements known as the reactants are converted into one or more different compounds/elements known as the products. The reactants and products will have an equal amount of atoms of the same elements. Example When iron and sulphur combine they form iron sulphide This can be represented using the following form (chemical equation) ?? + ? → ??? The compounds on the left-hand side of the arrow are the reactants and the products on the right. A + on the left-hand side can be thought of as “plus”, where as a + on the right-hand side can be thought of as “and”. For our program we will accept two reactants and two products. Model of a Pure Water Molecule Public Domain BACKGROUND – BALANCED CHEMICAL EQUATION Given the following chemical equation ?3?8 + ?2 → ?2? + ??2 On the left hand side we can see there are 3 carbon (C) atoms 8 hydrogen (H) atoms 2 oxygen (O) atoms On the right hand side we can see there are 1 carbon (C) atom 2 hydrogen (H) atoms 3 Oxygen (O) atoms As these are not equal the chemical equation is NOT balanced. To balance these we apply coefficients to the compounds. These coefficients multiply the number of atoms in the compounds. Hence a balanced version of the above equation is ?3?8 + 5?2 → 4?2? + 3??2 On the left hand side we can see there are 3 carbon (C) atoms 8 hydrogen (H) atoms 10 oxygen (O) atoms (5x2 =10) On the right hand side we can see there are 3 carbon (C) atom 8 hydrogen (H) atoms (4x2 = 8) 10 Oxygen (O) atoms (4x1 + 3x2 = 10) BACKGROUND – INPUT As we cannot use subscript, the number of atoms will be always to the right of the element symbol. Example: 4?2? will be written as 4H2O 2???4???2 will be written as 2BBe4CaH2 Errors: It is expected that all molecular formulas will be correctly formatted but may not be balanced. BACKGROUND - LIMITATIONS AND NOTES Error checking – User input The data entered by the user will be in the correct format of a chemical equation Number of compounds – User input Any of the products or reactants may be an empty String. User input The user input must accept any compound, i.e. do not hard code the compounds. Compounds and Elements An element will not appear twice in any single compound but may appear in both products and/or both reactants. The number of atoms for each element in any single compound will be between 1 and 9, but the total combined for the reactants and/or products may be higher Elements will be limited to those with 1 or 2 character element symbols CONSTRAINTS • Formatting needs to be as specified. (Your program will be tested against automated test cases.) • Text to user needs to be easily understandable. • The program must print your student number as specified. • Types should be used and named scientifically and appropriately. • You must use comments to explain significant lines of code. • The code must be done using ANSI C and compile on latcs5.cs.latrobe.edu.au using gcc. • You must not use break, goto, or global variables in the assignment. • You are only allowed to include the stdio.h, stdlib.h and string.h header file. No others. Do not use conio.h. • Checks must be commented out - NOT REMOVED - as they will be used in marking. • Do not change function prototypes TASK STOP: READ THE BACKGROUND INFORMATION FIRST PART 1 Given that the function numeric_char_to_decimal_int has been written for you. Add a comment above the function (not the prototype) numeric_char_to_decimal_int > Explain the parameters and what is returned > Explain what the function is for basically > Explain how the function works using proper terminology covered in the subject Given that the function get_coefficient has been written for you. The purpose of this function is that, given a compound (see background), it will find the coefficient if there is one, "remove" it from the string, and return the value, else it will return 1. Add a comment above the function (not the prototype) get_coefficient > Explain the parameters and what is returned > Explain how the function checks if there is a coefficient > Explain how the function "removes" the coefficient (is it really removed?) > Explain why the double pointer is necessary (why would this not work with a single pointer?) PART 2 Given the empty function and function prototype, get_compound Complete this empty function so that it behaves as follows: This function should ask the user for the compound, indicating the number n (see example below). Then should store the string response from the user. Once the function is written, check the code, using the checks provided in main. An example is shown below: Comment out the checks when done checking PART 3 Given the empty function and function prototype, remove_chars_from_str Complete this empty function so that it behaves as follows: This function takes as input a number, num. It then moves the characters in the string “to the left” by that number of characters, so as to shorten the string by num characters. Write the code that moves characters in the string, as to shorten the string by num characters Example: Given the string: 'H' 'e' 'l' 'l' 'o' '\0' (null terminator) And we want to remove the first two characters, the string becomes 'l' 'l' 'o' '\0' (null terminator) 'o' '\0' (null terminator) Notice that we don't move what is after the null terminator? You should understand why. 1. For loop that counts from 0, to the length of the string minus num (inclusive), incrementing by 1 2
