C, C++, OOPs & DSA Learning with programs

1. Why this Repository ?

• To strengthen the basics of C/C++ language concepts. I have implemented all the programs from 0 to advanced level.
• So, go through the files in sequential manner to understand "How to build logics".

2. VsCode Code-Runner extension settings to automatically removes binary files like: .exe or .out

• for Windows

  "code-runner.executorMap": {
    "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt -lm && $fileNameWithoutExt.exe && del $fileNameWithoutExt.exe",
    "cpp": "cd $dir && g++ $fileName -o $fileNameWithoutExt -lm && $fileNameWithoutExt.exe && del $fileNameWithoutExt.exe"
  },

• for Mac/Linux

  "code-runner.executorMap": {
    "c": "cd $dir && gcc $fileName -o $fileNameWithoutExt -lm && $dir$fileNameWithoutExt && rm $dir$fileNameWithoutExt",
    "cpp":"cd $dir && g++ $fileName -o $fileNameWithoutExt -lm && ./$fileNameWithoutExt && rm ./$fileNameWithoutExt",
  },

  Note: You can customize these settings as per your own need, my personalized configuration is:

  "code-runner.executorMap": {
    "java": "cd $dir && javac $fileName && java $fileNameWithoutExt && rm $fileNameWithoutExt.class",
    "c": "cd $dir && gcc-13 $fileName -o $fileNameWithoutExt -lm && $dir$fileNameWithoutExt && rm $dir$fileNameWithoutExt",
    "cpp":"cd $dir && g++-13 -std=c++17 $fileName -o $fileNameWithoutExt -lm && ./$fileNameWithoutExt && rm ./$fileNameWithoutExt",
    "python": "python3 -u",
  },

3. Fixes & Things worth knowing:

• <math.h> in VsCode fixed: if math.h isn't working in your VsCode, use -lm flag in execution command to link 'math' library.

     gcc test.c -lm
         or
     gcc test.c -o test -lm

• Alternatively use <cmath> header file in C++ programs then you won't need -lm flag.

• Use <cstring> header file instead of <string.h> to use C style pre-defined string functions like: strupr(), strcpy(), strcat() etc in C++ programs.

• cout is object of ostream class, and << is Insertion operator.

• cin is object of istream class, and >> is Extraction operator.
