问题 #include<stdio.h> int main() { void add(); int i=2; add(i++,--i); print("%d",i) } void add(int a,int b) { print("%d %d",a,b); } /*what are a and b's value i am actually not getting the answer why b is 2 */ 回答1: in line 6 where add() is called first args is i++ so it will send value 2 ie value of i to the function and then add 1 now i=3. second args is --i now it will subtract 1 and iwill now be 2 again and then send value 2 to function So I think your answer will print 2 2 (that is value of a

Double line breaks with 'pre' tag and 'nl2br'

由 心不动则不痛 提交于 2019-12-24 03:19:16
问题 I used nl2br function for pre tags, but I've encountered a strange problem: there are 2 line breaks but there's only one <br /> tag. For example: code in line 1<br /> code in line 2<br /> Displays as: code in line 1 code in line 2 instead of: code in line 1 code in line 2 回答1: Wrapping text in a <pre> tag will force it to be displayed as written: including spaces, tabs and new lines. Therefore the carriage return will create a new line AND the <br /> will create a second new line. 回答2: preg

CSS code highlighter - margin in pre code tag

由 为君一笑 提交于 2019-12-22 19:02:10
问题 Please look at this fiddle: Here What I am looking for is a way to remove that extra space at top (the one between black circular 1 and top edge of pre tag) in first example and make it look like second one The first example has some extra space above it (except the margin from strong elements), and I know that its because of the extra new-line after <pre><code> I didn't wanted to remove that extra newline as removing it makes the code look really unreadable, so I added this pre > code >

问题 http://jsfiddle.net/JamesKyle/L4b8b/ This may be a futile effort, but I personally think its possible. I'm not the best at Javascript or jQuery, however I think I have found a simple way of making a simple prettyprint for html. There are four types of code in this prettyprint: Plain Text Elements Attributes Values In order to stylize this I want to wrap elements , attibutes and values with spans with their own classes. The first way I have of doing this is to store every single kind of

问题 This question already has answers here : Closed 8 years ago . So I am stuck with this question. int i=5,a; a=++i + i++ + ++i + i++ - --i; printf("%d",a); According to me 'a' should be 20. a=6+6+8-8 However, on execution I found the answer to be 18. What I am doing wrong? A step by step explanation would be helpful. 回答1: This is undefined behavior . A variable cannot be changed more than once between sequence points. Your program can output anything. Any answer stating otherwise is wrong. 回答2:

How can I get a div that treats line breaks as significant to scroll if it exceeds a certain height?

由 雨燕双飞 提交于 2019-12-13 06:50:29

What should I do differently so that the DIV retains source line breaks, but has exactly the height I specify, with a scrollbar if the content height exceeds the maximum I have set? Thanks, 回答1: Just add overflow: auto or
