Lab 1 (SGN Lab/Review)Due Thursday at midnightTime: This lab is a relatively straightforward lab. You should be able complete it in 3 hours or less. You should be able to do it in one sitting (as long as that sitting doesn’t start at 9:00 pm Thursday night!!!!!)You may work on this during lab session. You may work with a partner on this lab (Be sure to submit your partner’s name on Canvas by Tuesday at 5:00pm!)Contents TOC \o "1-3" \h \z \u Purpose of this lab: PAGEREF _Toc50321537 \h 1How this lab works: PAGEREF _Toc50321538 \h 2What you need to do: PAGEREF _Toc50321539 \h 2For the lab you will need to do two things: PAGEREF _Toc50321540 \h 2/* Code */ PAGEREF _Toc50321541 \h 2Function Declarations (4 pts) PAGEREF _Toc50321542 \h 2/*Function 1 (2 pts) */ PAGEREF _Toc50321543 \h 4* How to print on the same line PAGEREF _Toc50321544 \h 4/*Function 2 (2 pts) */ PAGEREF _Toc50321545 \h 5/*Function 3 (3 pts) */ PAGEREF _Toc50321546 \h 5/*Function 4 (4 pts) */ PAGEREF _Toc50321547 \h 5/*Function 5 (4 pts) */ PAGEREF _Toc50321548 \h 6/*Function 6 (3 pts) */ PAGEREF _Toc50321549 \h 6/*Function 7 (3 pts) */ PAGEREF _Toc50321550 \h 7/*Function 8 (4 pts) */ PAGEREF _Toc50321551 \h 7/*Function 9 (4 pts) */ PAGEREF _Toc50321552 \h 7/*Function 10 (5 pts) */ PAGEREF _Toc50321553 \h 8/*Function 11 (4 pts) */ PAGEREF _Toc50321554 \h 8/*Function 12a (3 pts) */ PAGEREF _Toc50321555 \h 8/*Function 12b (5 pts) */ PAGEREF _Toc50321556 \h 9To Turn In: PAGEREF _Toc50321557 \h 9Purpose of this lab:This lab should serve a few purposes:Make sure your compiler is working properlyGet you familiar with C++ syntax and the differences between C and C++Refresh your memory for codingGet you used to my style Ease you back into a crazy semesterAllow you to experience the joy and happiness of writing functions and getting your code to workHow this lab works:This lab is in essence a decoder lab. If you write the functions as described successfully, and run it with the main I’ve given you, you will decode the input I’ve given into intelligible output. Hint – if your output is gibberish, you did something wrong.What you need to do:In eclipse, create a new project. Once you’ve created a project, create a new source file. If you are not familiar with how to do this, please watch my introductory videos on my web site (https://www.eecis.udel.edu/~yarringt/CISC220 ). I go over how to create a project and a source file, and then how to compile.Once you’ve created your source file (make sure it has a .cpp extension!), copy my code below.For the lab you will need to do two things:Fill in the function declarations, above the mainFill in the function definitions, as described in main, below the main.(If you do not know the difference between the function declarations and the function definitions, I highly recommend you watch week 1’s videos on my web site, https://www.eecis.udel.edu/~yarringt/CISC220 )NOTE: DO NOT TOUCH THE MAIN FUNCTION!!!!! DID YOU HEAR ME? DON’T TOUCH IT. EVEN THOUGH YOU MIGHT WANT TO, RESIST THE TEMPTATION. YOU CAN DO IT!! JUST COPY AND PASTE THE WHOLE THING, ADD THE FUNCTION DECLARATIONS AT THE TOP, AND THEN BELOW THE MAIN FUNCTION, FILL IN THE FUNCTION DEFINITIONS AS DESCRIBED RIGHT ABOVE THEM. THAT’S IT. JUST STEP AWAY SLOWLY FROM THE MAIN FUNCTION. DON’T TOUCH IT.(Okay, if you want to comment things out in main as you’re working on the different functions, and then remove the comments as you go, that’s fine. But my point is, you don’t have to write any code in the main function. It’s done for you.)/**********************************************************************************//* Code */#include <iostream>#include <stdlib.h>#include <string.h>using namespace std;/********************************************************Function Declarations (4 pts)Fill in function declarations here********************************************************/int main() {cout << "Hello World!" << endl;string str0 = "ha";int x = 12;func1(str0,x);/*****************************************************/string string1 = "ketxlurbaesrwainuts"; // 19 characters totalfunc2(string1,19);/*****************************************************/string string2 = "psheskmarcaphulc";func3(string2,16);/*****************************************************/ string str3 = "blek_vpbq_utxsreknmoihs_neubr_symluljiwsez_aksivnzdw"; func4(str3,52,6,34);/*****************************************************/string base1 = "woelihnbatmeudoirhdxkj";int orig[] = {2,4,1,7,2,-2,3,1,3,7,-8};func5(base1,22,orig,11,3);int orig2[]={2,1,3,2,1,-2,8,-3,9,-1,3};func5(base1,22,orig2,11,5);/*****************************************************/string s4 = "ekvmburwacvxezq_ypotural_ukinvnterzs_powezikrdpvnbjesbsk!";func6(s4, 57, 3, 4);/*****************************************************/char arr5[] = {'a','s','x','j','t','i','h','o','q','e','p','w','v','t','z','m','i','h','y','m','k','d','i','c'};int len = 24;func7(arr5,len,7);/*****************************************************/ string s6 = "xezuhnbl_uiplypdhqlb"; len = 20; int arr6[] = {2351,92837,482,65,1039,233,23095,1,2037,693842,283}; int len2 = 11; func8(s6,len,arr6,len2);/*****************************************************/ string s7 = "gboehdkixkwpmngzicosygmeuqlaltcvwdge"; len = 36; func9(s7,len,6);/*****************************************************/ string s8 = "gboehdpixkwpangzicjsygmeaqlaltmvwdgeabndckswoshbk"; len = 49; func10(s8,len,7);/*****************************************************/ string s9 ="w_orp_eshmueryasaa_nootetkdtbueteei_ars!vsfib_t!e_fslg_!rye_yra_"; len = 64; func11(s9,len,8);/*****************************************************/ string somechars="rstlne"; string test = "arktole"; for (int i = 0; i < 7; i++) { if (func12a(somechars,6,test[i],0)) { cout << test[i] << " in charset"<<endl; } else { cout << test[i] << " not in charset"<<endl; } } /*****************************************************/string decipher = "bchzxivkjndpqsjiffrguxhjtb_firskz_azlckmjoxkrspktc_ctprwepjznftjkyzxtkpwvueqnrqtckuyb!";int len1 = 86;string notchars = "bcfjkpqruvxz";int len1a = 12;func12b(decipher,len1,notchars,len1a,0);return 0;}/**********************************************************************************//* Function Definitions *//* This is where you write the function definitions *//**********************************************************************************//*****************************************************//*Function 1 (2 pts) *//*Write a function that takes the string string0 and an integer * and prints that string the integer number of times.

Because if for some reason the program you wrote compiles and runs on your computer, but it does not compile or run on the TA’s computer, with a screenshot of the running code, we will make an appointment to see your code run rather than just give you a 0. This happens when we’re using different compilers sometimes (even with MacOSX vs MINGW compiler!)
