title: How to use 32-bit pointers in 64-bit application?
body: <p>Our school's project only allows us to compile the c program into 64-bit application and they test our program for speed and memory usage. However, if I am able to use 32-bit pointers, then my program will consume much less memory than in 64-bit, also maybe it runs faster (faster to malloc?)</p>
  
  <p>I am wondering if I can use 32-bit pointers in 64-bit applications?</p>
  
  <p>Thanks for the help</p>
