title: C programming: Using a variable inside another variable name (not sure of the technical term)
body: <p>I don't know what the technical term is but I would like to do following:</p>
  
  <pre><code>int var_a;
  int var_b;
  int var_c;
  char letter;
  
  letter = 'b';
  printf("%d", var_'letter');
  </code></pre>
  
  <p>However, I don't want to use if statements. Can I directly sub in the rest of the variable name with the variable char so that the computer would see "var_b"?</p>
