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-1The 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:
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by the way, I cannot get XCode IDE because my 2012 iMac is outdated and does not support higher macOS: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-pointersI 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: ./addressOfcpp-memory % chmod +x addressOf
cpp-memory % ./addressOf
Value: 7
Address: 0x7ff7b9eef878
