Sorting Visualizer using SDL2

visualizer1

Visualization of different sorting algorithms in C++ with SDL2 Library. You can also run Sorting Visualizer using the C++ source code available in the repository.

Installing SDL2

sudo apt-get install libsdl2-dev libsdl2-ttf-dev

Compiling

g++ source/* -o sort.out -lSDL2 -lSDL2_ttf -Iheaders

Running the program

Available controls:

  • 0: generate a different randomized array.
  • 1: start/pause Bubble Sort Algorithm.
  • 2: start/pause Selection Sort Algorithm.
  • 3: start/pause Insertion Sort Algorithm.
  • m: open/close the menu
  • q: exit out of Sorting Visualizer

Valgrind

Valgrind reports memory leaks in the openGL library and can be suppressed using a suppresion file. More information about Valgrind Suppression can be found on the wiki: https://wiki.wxwidgets.org/Valgrind_Suppression_File_Howto

sudo apt install gawk

# log all errors to file
valgrind --leak-check=full --show-reachable=yes --error-limit=no --gen-suppressions=all --log-file=supdata.log ./sort.out

# create suppression file
cat ./supdata.log | ./parse_valgrind_suppressions.sh > sort.supp

# Running valgrind with suppression file
valgrind --leak-check=full --show-reachable=yes --suppressions=sort.supp ./sort.out
