Body
As indicated by the other answers, the problem was caused by the carriage return. There are many ways solve this, some more complex than others. Therefore I will indicate the simplest method I've found: As <a href="http://www.gnu.org/software/libc/manual/html_node/Character-Input.html" rel="nofollow">the GNU website indicate</a> the most appropriate function for this is <code>getc(stream)</code> and I quote: <blockquote> This is just like fgetc, except that it is permissible (and typical) for it to be implemented as a macro that evaluates the stream argument more than once. getc is often highly optimized, so it is usually the best function to use to read a single character. </blockquote> I put it into practice but it still have the CR problem, so I printed the result of this function and notice that it return 10 when CR. After this I tried to get functionality and clarity for the code. Doing everything possible for this, now my code is the following: <pre class="lang-c prettyprint-override"><code>main() { char a,b; printf("\nEnter the first char.. "); if ((a=getc(stdin))==10) a=getc(stdin); printf("\nEnter the second char.. "); if ((b=getc(stdin))==10) b=getc(stdin); printf("\nFirst char --> %c",a); printf("\nSecond char --> %c",b); } </code></pre> And the nice output: <blockquote> First char --> z Second char --> z ('z' or the char there I wan to) </blockquote> <hr> I've learned that all the programs need they own solution, different than the others, and that is the reason (I think) for that are so many functions. What I can say is "Always have to adapt the program. Maybe this sentence works for me but is not guaranteed that gonna work for other codes." Thanks to all the guys that helped me!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
