Answers like this one have full page scroll-bars, which seems wrong. I am simply trying to have 100% height html and body with no browser scrollbar, but scrolling visible on the body content area only. It needs to behave with bootstrap menu heights etc. So far the only way seems to work, at all, is using absolutely position content and footers elements. html

Is there a way to do that using CSS? e.g. Sample text showing wrapping of text in only two line... Thanks 回答1: Limiting output to two lines of text is possible with CSS, if you set the line-height and height of the element, and set overflow:hidden; : #someDiv { line-height: 1.5em; height: 3em; /* height is 2x line-height, so two lines will display */ overflow: hidden; /* prevents extra lines from

I'm mostly interested in using a corruption or modification of the chunk metadata for the basis of the attack, but I'm also open to other suggestions. I know that my goal of the exploit should be do overwrite the printf() function pointer with that of the challenge() function pointer, but I can't seem to figure out how to achieve that write. I have the following piece of code which I want to exploit, which is using malloc from glibc 2.11.2 : void challenge() { puts("you win\n");

The compiler can

While Microsoft's documentation indicates that the range for doubles should reach ~1.8E308, I am receiving an overflow error for numbers significantly lower than that threshold.

The C standard states If an exceptional condition occurs during the evaluation of an expression (that is, if the result is not mathematically defined or not in the range of representable values for its type), the behavior is undefined. Are there compiler switches that guarantee certain behaviors on integer overflow? I'd like to avoid nasal demons. In particular, I'd like to force the compiler to wrap on overflow. For the sake of uniqueness, let's take the standard to be C99
