University of Illinois CS_400: Object-Oriented Data Structures in C++

I decided to take a refresher on my C++ skills.

The University of Illinois (U-C) had a class on Coursera: "Object-Oriented Data Structures in C++"

https://www.coursera.org/learn/cs-fundamentals-1

The funny thing is, that I actually learned C/C++ at the University of Illinois (UIC), just over 20 years ago!

Getting the instructor's code:

Uki@iMac 18:38 Coursera_OO_data_structures_Cpp $ cd ..
Uki@iMac 18:38 _REPOS $ git clone https://github.com/wadefagen/coursera.git coursera-cs400
Cloning into 'coursera-cs400'...

Setting up macOS for C++

I am following these instructions:

https://courses.engr.illinois.edu/cs225/sp2019/guides/own-machine/#macos

Install Apple XCode

$ xcode-select --install
xcode-select: error: command line tools are already installed, use "Software Update" to install updates

IMPORTANT, if you get Xcode errors when running the make command, execute this command:

sudo xcode-select --reset

by the way, I cannot get XCode IDE because my 2012 iMac is outdated and does not support higher macOS:

Getting BREW

$ /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

the above will take quite a few minutes.

Once BREW is installed, install the following:

brew install ghostscript
brew link --overwrite freetype

 

brew install imagemagick

brew link --overwrite libtool

 

brew install graphviz 

brew install cmake

brew edit valgrind

This will open your default code editor. In the opened file, change the URL in the head section from https://sourceware.org/git/valgrind.git 

to 

git://sourceware.org/git/valgrind.git 

and run the following:

brew update brew install --HEAD valgrind

Test MAKE

$ cd /Volumes/GoogleDrive/My\ Drive/_REPOS/coursera_wadefagen/cpp-std
cpp-std $ make

xcrun: error: active developer path ("/Volumes/SSD500GB/Applications/Xcode.app/Contents/Developer") does not exist

2.1 Stack Memory and Pointers
https://www.coursera.org/learn/cs-fundamentals-1/lecture/Iccq3/2-1-stack-memory-and-pointers

I got to use Microsoft Code and Terminal properly

How to make the compiled files execute in the command line?

If you get a similar error, you might have to change the mode to execute the file..

zsh: permission denied: ./addressOf

cpp-memory % chmod +x addressOf
cpp-memory % ./addressOf
