title: Effect of Online Compiler on computer's memory
body: <p>When we declare any variable, particularly in C/C++, it is allocated in computer’s memory according to its data-type (and machine also). The question I have is, when we run the program in online IDEs, does memory of my PC/machine get used? </p>
  
  <p>This question is meant more for the matter of dynamically allocating memory in C, because, for whatever reason, if we misuse the pointer in arguments of function like <code>malloc()</code>, <code>calloc()</code>, especially <code>free()</code>, it is possible that computer memory gets damaged to some extent (Memory Leakage).</p>
  
  <p>Therefore, if online compilation do not use the computer memory, then I can probably use these functions on an online IDE, but I don't know what the case is. Is it safe? </p>
