Cheat Sheet
- Mastering Pointers and Address Arithmetic -
Pointers are variables that store memory addresses, letting you directly access and manipulate data (K&R C, Ch. 5). Remember that pointer arithmetic moves in units of the pointed type (e.g., incrementing an int* advances by sizeof(int)). A handy mnemonic: "& gives the address, * unpacks the treasure."
- Understanding Data Types and Integer Promotion -
C's basic types (char, int, float, double) follow strict size and signedness rules defined by the ISO C standard. Implicit promotions - like converting a char to an int in expressions - ensure consistent calculation results but can introduce subtle bugs. Keep a type-casting cheat sheet handy to avoid surprises.
- Dynamic Memory Management with malloc and free -
Dynamic allocation via malloc(), calloc() and free() from
is crucial for flexible data structures (e.g., linked lists) as taught in university CS curricula. Always check for a NULL return and call free() to prevent memory leaks. Think of malloc/free as borrowing and returning library books: never keep them past due! - Operator Precedence and Associativity -
Knowing that * (multiplication) binds tighter than + (addition) and that ++ has higher precedence can save you from logic errors (see ISO C ยง6.5). Use parentheses to make your intention crystal clear when chaining operators. When in doubt, break complex expressions into smaller statements.
- Efficient String Handling and Buffer Safety -
C strings are null-terminated char arrays, so always leave room for the '\0' terminator to avoid overflow (as emphasized by CERT C Secure Coding). Use strncpy() or snprintf() in place of strcpy() and sprintf() for safer copying. Mnemonic: "Terminate and allocate before you calculate."
