Control Structures: C provides control structures like loops (for, while, do-while) and conditional statements (if-else, switch-case) for flow control and decision-making in programs. Functions: C programs are typically composed of multiple functions. Functions encapsulate blocks of code that can be called and reused. C allows both standard library functions and user-defined functions. Pointers: Pointers are a powerful feature of C that allow direct manipulation of memory addresses. They enable efficient memory management, array operations, and working with data structures like linked lists and dynamic memory allocation. Arrays and Strings: C supports arrays, which are collections of elements of the same data type. Strings are treated as character arrays and have specific functions for manipulation and processing. Input and Output: C provides standard input/output functions for reading input from the user (scarf) and printing output (print) to the console. File handling functions allow reading from and writing to files. Preprocessor Directives: C uses preprocessor directives that start with a '#' symbol. These directives are processed before the compilation and can be used for macro definitions, conditional compilation, and including header files.
