Review of certain C and C++ features

• Pointers:
  • Passing by pointer vs. passing by reference to functions
  • Demonstration of pointer properties and pointer arithmetic
• Low-level: C-style string - \0 terminated char array:
  • Simple operations on strings
  • How <cstring> library functions work - the idea
  • Extracting data and converting into numbers - atoi/atof   The same - atoi/atof - but using pointer notation
  • Extracting data and converting into numbers - sscanf
  • Converting numbers into strings (print to a char array buffer)
• Processing file data with parsing
  • data file: wifi.txt
  • direct stream parsing
  • parsing with string and stringstream
  • parsing with char[] and stream
  • parsing with char[] and with atoi or atof
• Binary number representation:
  • signed vs. unsigned variables, some binary operations and bit shifting
• Useful Windows functionality:
  • accessing joysticks
