C
a day ago
- C uses #include to insert entire file contents, not import modules.
- #define and #ifdef are used for constant definitions and conditional compilation.
- The 'static' keyword provides file-scope privacy, similar to private in other languages.
- Pointers store memory addresses; functions can modify variables via pointers.
- Array indexing (a[0]) is equivalent to pointer dereference (*a) and other forms like *(a+0), *(0+a), and 0[a].
- Assigning an array (not an element) to an integer variable causes a compilation error.
