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.

```#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>
