title: Pointer to stored specific memory address
body: <p>I have memory location address in a txt file. I want to read the address from the file and use the value stored at that address. Here's what I've done:</p>
  
  <pre><code>char line[10];
  FILE *f;
  f=fopen("p:\\address.txt", "r");
  fgets(line,10,f);
  </code></pre>
  
  <p>The file contains the address 0x12ff30. I have stored this in the char array line. The address contains a double value (8 bytes from 0x12ff30). Now how do I create and use a pointer to get the value stored at that address?</p>
  
  <p>Thank you.</p>
