RunC-without_warning_flag-KS

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.

# Streams in C

The standard C library (linked to using `#include <stdio.h>`) includes a handful of functions for performing input and output in C.

C and UNIX make use of a concept called **streams** in which data can be sent and received between programs, devices, and the operating system. We can distinguish between two types of streams: text and binary.

- Text streams are made up of lines, where each line has zero or more characters, and is terminated by a new-line character `\n`. 
- Binary streams are more “raw” and consist of a stream of any number of bytes.

C programs all have three streams “built-in”: **standard input**, **standard output**, and **standard error**. Here are some examples of how standard input and standard output streams are used:

- When we interact with a C program in a terminal, and type values in to pass to the program, we are using standard input.

 - UNIX has a concept called **pipes** whereby we can redirect any stream (e.g. output from some program or device) as input to another process (e.g. your program). When we redirect a stream to our program, which takes it in as input, we are using the standard input stream. 

- When our program uses `printf` (see below) to print to the screen, we are using standard output.

- Files (e.g. data files) are also associated with streams, and we'll see below how to read from them and write to them.

We won’t talk about standard error here. Refer to a UNIX reference, or a C book for more details on standard error.

# Character I/O: `getchar` and `putchar`

When we want to read data a single character at a time, we can use the function `getchar`. The output function `putchar` writes out one character at a time to standard output. Run `./main` from the terminal to see this:

Delve into the input/output methods provided by the C standard library and learn how to interact with the command-line terminal.
