title: Increase Char value by one
body: <p>I have the following code:    </p>
  
  <pre><code>char buf[] = {0x45, 0x76, 0x72, 0x23, 0x12};
  int main(void)
  {
      int i;
      for (i = 0; i&lt;=sizeof(buf); ++i){
        printf("%c\n", buf[i]); 
      }
  }
  </code></pre>
  
  <p>What I want to do is take <code>buf[i]</code> when it is printed out and and make 0x45 read 0x46. Essentially, how do I add 1 to each value as it is going through the for loop?</p>
