title: Printing a character multiple times in a for loop
body: <p>I want to use printf and for loop to print a character multiple times per line depending on the input; i.e. if the input is 3 i want to print:</p>
  
  <pre><code>a
  aa
  aaa
  </code></pre>
  
  <p>this is the loop, which doesn't work at all.</p>
  
  <pre><code>for (int i = 0; i &lt; n; i++)
  {
      printf("a", i);
      printf("\n");
  }
  </code></pre>
  
  <p>I just don't understand how to print it multiple times on a single line.</p>
