 * Disreption: simple vector addition example that shows how 
 *      for loops could be used to initialize the vector
 *      elements to some value, doing compuation, and how to
 *      print an array of fixed number of elements. For loops
 *      are basically used to repeat an operation a fixed 
 *      number of times. 
 * How Compile: gcc for_loop.c -o for_loop.exe
 * How to Run: ./for_loop.exe
