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.

What value will be printed as the size of `s`?
```C
int main(void) {
  char s[] = "table";
  printf("s is %ld elements long\n", sizeof(s));
  return 0;
}
```

What value will be printed as the size of <code>s</code>?
<pre><code class="language-C">int main(void) {
 char s[] = &quot;table&quot;;
 printf(&quot;s is %ld elements long\n&quot;, sizeof(s));
 return 0;
}
</code></pre>

What's the correct way to modify the string `x` initialized as
```C
char x[] = "This is a bat and ball"; 
```
so that it's shortened to 
```C
"This is a bat"
  ```

The function `atof` converts a string  into a floating-point number.

The function `sprintf` is used to convert an integer or a floating number to a  string.

The function `atoi` converts a string into an integer

You can simply use the `==` operator to test whether two strings are equal
