title: Where exactly do function pointers point?
body: <p>Given that all the primitive data types and objects have memory allocated, it is intuitively easy to imagine the pointers to these types.</p>
  
  <p>But where exactly do function pointers point to? Given that instructions are converted into machine code and reside in memory, should we consider they point to the memory location corresponding to the start of the functions instructions?</p>
  
  <p>We face many errors in pointers due to illegal memory access. Is it the case that errors occur when function pointers point to data memory instead of instruction memory?</p>
