This comprehensive course covers the fundamentals and advanced concepts of C programming to build a solid foundation for your programming journey. You’ll learn about essential topics like data types, variables, constants, and C statements, along with deeper explorations of control flow in C, including for loops and conditional statements in C. You’ll also learn about C functions, scope of variables, function arguments, and work with arrays, strings, and pointers in C.

You’ll gain hands-on experience with dynamic memory allocation, stack vs. heap, C standard library, and advanced topics such as binary files, input and output streams, and header files. The course also teaches compiling in C, linking in C, and debugging with tools like GNU debugger (GDB) and gprof for code profiling. By mastering these concepts, you’ll confidently program in C and optimize your code using gcc optimization flags.

**Constants** are values that do not change after they have been defined. These values can be of different types.

# Numeric constants

An example of an `int` constant is the number `1234`. An example of a floating-point constant (by default typed as a `double`) is `123.4`. Another example of a floating-point constant is `2e-3` (which represents 2 x 10<sup>-3</sup> in scientific notation). We can also write numbers in octal or hexadecimal representations instead of decimal: octal by using a leading zero (`0`) and hexadecimal by using a leading zero followed by an x (`0x`). Decimal `31` can be written as `037` in octal and `0x1f` or `0X1F` in hexadecimal. Here are some examples of how numeric constants are created and then assigned to variables:
