String.h
string.h is the C standard library header declaring functions for manipulating strings, character arrays, and related memory sequences.
Modern C, Third Edition
string.h is the C standard header that declares functions for manipulating strings and related memory sequences.
- How it is used
- Supports string manipulation and bounded operations on character arrays within the C standard-library interface.
- How deep it goes
- Defines function families, termination rules, size constraints, and a combined copying example without descending into implementation internals.
- Examples
- Uses argv[0], strlen, memcpy, strcmp, and a variable-length array to verify a copied program name.
- What you can do after
- Apply string.h functions to copy, compare, search, and measure terminated strings or bounded character arrays.
Modern C
string.h is the C standard library header declaring functions for manipulating character arrays and null-terminated strings.
- How it is used
- Provides C interfaces for copying, comparing, searching, and measuring character arrays and null-terminated strings.
- How deep it goes
- Defines representative functions, declarations, and termination requirements, but stops short of deeper implementation details.
- Examples
- Uses program-name copying and multiple character-array initializations to expose lengths, terminators, and destination sizing.
- What you can do after
- Apply string.h functions while checking zero termination, array lengths, and destination capacity.
