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

What will be printed to the screen?
```C
void sum(int a, int b) {
  int sum = a + b;
  return sum;
}

int main(void) {
  int x = 3, y = 4;
  printf("%d", sum(x, y));
  return 0;
}
```  


What will be printed to the screen?
<pre><code class="language-C">void sum(int a, int b) {
 int sum = a + b;
 return sum;
}

int main(void) {
 int x = 3, y = 4;
 printf(&quot;%d&quot;, sum(x, y));
 return 0;
}
</code></pre>

What will be printed to the screen?
```C
void my_func(int x, int y) {
  x = y * 4;
  y = x + 10;
}
    
int main(void) {
  int x = 5;
  int y = 9;
  my_func(x, y);
  printf("x = %d, y = %d", x, y);
  return 0;
}
```    

  
  


What will be printed to the screen?

}
</code></pre>

What does this code print?

```C
#include <stdio.h>

int foo(void) {
 static int num = 0;
 num++;
 return num;
}

int main(void) {
 int i, returned_val;

 for (i = 0; i < 3; i++)
 returned_val = foo();
 printf("The last value returned is %d\n", returned_val)

 return 0;
}
```

What does this code print?
<pre><code class="language-C">#include &lt;stdio.h&gt;

int foo(void) {
 static int num = 0;
 num++;
 return num;
}

int main(void) {
 int i, returned_val;

 for (i = 0; i &lt; 3; i++)
 returned_val = foo();
 printf(&quot;The last value returned is %d\n&quot;, returned_val)

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

What kind of a variable is `x`?

```C
#include <stdio.h>

long x = 5;

int main(void) {
 ++x; 
 return 0;
}
```

What kind of a variable is <code>x</code>?
<pre><code class="language-C">#include &lt;stdio.h&gt;

long x = 5;

int main(void) {
 ++x; 
 return 0;
}
</code></pre>
