Do you want to get a grip on the basic programming concepts from scratch? Do you feel the need to have a better and enhanced understanding of how it all works?  Well, you've come to the right place. This course outlines data types, control flow, functions, input/output, memory, compilation, debugging and other advanced topics in a comprehensive, yet concise manner.

C is where it all begins and where you should also begin to embark on your programming journey. The incredibly efficient and powerful C language forms the basis for many other languages like C++ and Java. It allows you to interact directly with memory and low-level computer operations, thereby enhancing your programming skills and deepening your understanding. This comprehensive and detailed course will introduce you to all the basic and advanced programming concepts of C language. In addition, it also addresses memory, debugging and parallel programming in C.

Sounds awesome? Let's dive in!

Learn C from Scratch

```#define YES 1``` assigns a symbolic name to program constant

The `#define` directives can appear anywhere in the program

A `#define` directive is similar to variable assignment 

The preprocessor replaces each use of a macro defined using a `#define` directive with the contents of that macro before the program is compiled.

Which statement is NOT true about `#define`?

Which statement is NOT true about <code>#define</code>?

Both of the above definitions are unproblematic.

Which macro body will correctly implement the logical AND of its two arguments once the macro is expanded?

Which macro body will correctly implement the logical AND of its two arguments once the macro is expanded?

What’s printed by the following code?

```C
#include <stdio.h>

#define VERSION 2.1

int main(void) {
 
 #ifdef VERSION
 printf("Version: %.1f", VERSION);
 #else
 printf("Unversioned content"); 
 #endif

 return 0;
}
```

What’s printed by the following code?
<pre><code class="language-C">#include &lt;stdio.h&gt;

#define VERSION 2.1

int main(void) {
 
 #ifdef VERSION
 printf(&quot;Version: %.1f&quot;, VERSION);
 #else
 printf(&quot;Unversioned content&quot;); 
 #endif

 return 0;
}
</code></pre>

Error: Something went wrong! Error code: 111. 

Error: Something went wrong! Error code: 111.

Error: Something went wrong! Error code: 111.

What’s the output of the following code?

```C
#include <stdio.h>

#define CATCH(e, ...) if (e) { printf( "Error: " __VA_ARGS__); e = 0; }

int main(void) {
 int error = 1;
 CATCH(error, "%s %s\n", "Something went wrong!", "Error code: 111.")
 CATCH(error, "%s %s\n", "Something went wrong!", "Error code: 111.")
 return 0;
}
```

What’s the output of the following code?
<pre><code class="language-C">#include &lt;stdio.h&gt;

#define CATCH(e, ...) if (e) { printf( &quot;Error: &quot; __VA_ARGS__); e = 0; }

int main(void) {
 int error = 1;
 CATCH(error, &quot;%s %s\n&quot;, &quot;Something went wrong!&quot;, &quot;Error code: 111.&quot;)
 CATCH(error, &quot;%s %s\n&quot;, &quot;Something went wrong!&quot;, &quot;Error code: 111.&quot;)
 return 0;
}
</code></pre>
