Techniques 1
String operations: Use length positions and substrings carefully
Concatenation and comparison: Join text or test it using the stated rules
Text-file reading: Open read and close using a defined format
Text-file writing: Write append or overwrite deliberately
Techniques 2
SQL selection: Retrieve chosen fields from matching records
SQL filtering: Use exact conditions and compatible types
Arrays and lists: Index multiple values under one structure
Static arrays: Declared array length can be fixed
Techniques 3
Two-dimensional arrays: Use row and column indexes
Records and structures: Group related fields with different meanings
Functions and procedures: Reusable subprograms have defined interfaces
Benefits of subprograms: Reuse and separate responsibilities
Techniques 4
Scope of values: Local and global names have different visibility
Passing and returning arrays: A subprogram can process a whole collection
Random numbers: Use the range defined by the operation
Programming practice: Combine constructs in a working solution
Connections
Techniques 1 → Techniques 2: File text needs deliberate conversion or interpretation before structured use.
Techniques 3 → Techniques 4: Subprogram interfaces and scope determine how collection values are shared.
