• Create your work directory inside the section
  • https://github.com/mcu-india/CPL/Basics/<user>
• Always add a README.md in directory
• Use Nouns for variables and Verbs for Fuctions
• Document your code
• Use a text editor to write code - Vi, Notepad, Notepad2, Notepad++, etc.
• Compile your code on command line in Visual Studio developer command prompt
  • Use /Zi option to generate *.pdb files for debugging
• Build and run same code with 32 bit compiler and 64 bit compilers

Coding Convention

• Every .c file should have an associated .h file
• Use #define guards in header files to prevent multiple inclusions

    #ifndef __MY_HEADER_H
    #define __MY_HEADER_H
    ...
    #endif // __MY_HEADER_H
  

• Include .h files for function and data type declarations
• Avoid function inlines unless they are smaller than 10 lines
• While definign function parameters, add all input parameters before output parameters
• Use four space indentation
• Functions

    return_type FunctionName(arg_type args1,
                             arg_type args2)
    {
        ....
    }
  

• Loops and Conditions

    if(condition){
        ...
    }
  

• Single point of exit from functions as much as possible
  • Use 'goto' to achieve that

      int func()
      {
          int status = STATUS_UNSUCCESSFUL;
          ...
          if(error){
              // log
              goto exit;
          }
          ...
          status = STATUS_SUCCESS;
          
      exit:
          return status;
      }
