Searching & Sorting

• Processing data is a fundamental operation in Computer Science
• Two fundamental operations in processing data are searching and sorting
• Form the basis or preprocessing step of many algorithms
• Large variety of algorithms have been developed

Encapsulation: Structures & Objects

---

• Built-in primitive types (int, double, char) are limiting: not everything is a number or character
• Real world entities are made up of multiple pieces of data
• Example: Lab 10 sorting "teams"

File I/O

• A file is a unit of stored memory, usually on disk
• A file can also be... directories, buffers (standard input/output are files), a socket could be a file, a program is a file
• You can write to and read from a file
• Files may be plaintext or binary (or plaintext but not intended for human consumption: EDI, XML, JSON, base-64 encoding)
• The basic steps to follow are:
  1. Open the file
  2. Process the file

String Processing

• Strings represent data that may need to be processed
• Common to deal with CSV (Comma separated value) or similar formatted data
• Standard library functions can help, but processing involves designing algorithms

More Convenience functions in C

• There is a ctype.h library that provides several "check" functions for single characters: isalpha(c), isdigit(c), islower(c), isupper(c), isspace(c), conversion: toupper(c), tolower(c), etc.
