====== Lab04 - Strings and (de)allocation ======

==== Valgrind ====
  * use ''valgrind'' for memory leak detection
  * can detect forgotten allocated memory and the exact location of out-of-bound access
  * can report using uninitialized variables/memory
  * for better output, compile your program with ''-g'' flag
  * ''valgrind ./your-program''

==== Documentation ====
  * [[https://en.cppreference.com/w/c]]
  * learn to understand the function declaration (the name, return type, and parameters) 
  * the definition (code to be executed) might not always be available

==== Strings ====
  * Remember you can use ''#include <string.h>'' for helper functions
  * Let's declare an array of characters, and then ask the user for their first name
  * Print the name, its length, and say if it's the same as your own name
  * You can use the function ''strcmp'' to compare the strings, will return zero if the same

==== Dynamic memory ====
  * Modify your program to use dynamic memory for the name
  * Ask the user for other names
  * Use ''realloc'' to make the original name string bigger
  * Use ''memcpy'' to append the additional name to the original name/string

==== Task 1 ====
  * Write a program which allows the user to enter “infinite” amounts of text, and will keep appending it to a string (char array).
  * When they press enter, it will output the current string.
  * If they enter a certain character, it will close.
  * Use the ''getchar()'' function to get letters from the command line.
  * You will need to use ''malloc()'' and ''realloc()'' to control the memory.
  * Don’t forget to use ''free()'' at the end to free the memory.

==== Task 2 ====
  * Update the previous code to read a whole word from the input.
  * Implement your own version of the ''strcmp()'' function from the string.h library.
  * Hard-code your name into your program, and ask the user to input words.
  * If it matches your name, print a message!
  * Can you make it case insensitive?
