title: Can you define the size of an array at runtime in C
body: <p>New to C, thanks a lot for help.</p>
  
  <p>Is it possible to define an array in C without either specifying its size or initializing it. </p>
  
  <p>For example, can I prompt a user to enter numbers and store them in an int array ? I won't know how many numbers they will enter beforehand.</p>
  
  <p>The only way I can think of now is to define a max size, which is not an ideal solution...</p>
