title: Converting Decimal to ASCII Character
body: <p>I am trying to convert an decimal number to it's character equivalent.  For example:</p>
  
  <p>int j = 65 // The character equivalent would be 'A'.</p>
  
  <p>Sorry, forgot to specify the language.  I thought I did.  I am using the Cocoa/Object-C.  It is really frustrating.  I have tried the following but it is still not converting correctly.</p>
  
  <pre><code>char_num1        = [working_text characterAtIndex:i];   // value = 65               
  char_num2         = [working_text characterAtIndex:i+1];    // value =  75
  char_num3         = char_num1  + char_num2;         // value = 140                                      
  char_str1   = [NSString stringWithFormat:@"%c",char_num3];  // mapped value = 229
  char_str2   = [char_str2 stringByAppendingString:char_str1];    
  </code></pre>
  
  <p>When char_num1 and char_num2 are added, I get the new ascii decimal value. However, when I try to convert the new decimal value to a character, I do not get the character that is mapped to char_num3.</p>
