Program Name: Filter-Uniq-Ints

Purpose: filter out unique integers from an unsorted integer array. E.g. {1,2,1,3} should be filtered to {1,2,3}

You need a C compiler to build the c-branch. For the cpp-branch, you also need CMake > 3.20.

• For Microsoft Windows users, mingw-w64 is recommended
• For GNU/Linux Distro or other *nix users, the GNU Compiler Collections, known as gcc, is a perfect one
• For macOS users, clang is easy to install and use (brew is not needed to install clang on macOS).

NOTE: Please choose a branch before build this project.

1. Use git to clone this code: git clone https://github.com/zhenrong-wang/filter-uniq-ints.git
2. Change your directory: cd filter-uniq-ints

For the c-branch

3. a. Build with the C compiler: gcc *.c -Ofast -Wall -o YOUR_PROGRAM_NAME

For the cpp-branch:

3. b. Configure CMake: cmake -B cmake-build-release -DCMAKE_BUILD_TYPE=Release
4. b. Build command example: cmake --build cmake-build-release --config Release --target all
5. b. Change your directory: cd cmake-build-release
6. b. Build with make: make

Command Format: cmd argv[1] argv[2]

• argv[1]: A string to specify an integer as the number of elems input. E.g. 10032
• argv[2]: A string to specify an integer as the maximum random number generated. E.g. 1000
