c++ - Does a vector<std::array<float,10>> of size 5 result in 50 contiguous floats? -


this question has answer here:

the suggested duplicates not directly answer particular question. 1 of them addresses contiguity of elements of vector without talking array while other discusses use of array instead of float[n] without talking contiguitiness (is word?).

does vector<std::array<float,10>> of size()=5 result in 50 contiguous floats in memory, such pointer vector[0] element points start of stretch of memory?

yes. @ least if create one.

arrays not copyable in c++ have hard time trying insert them in array.

update: yes, vector<array<float, n>> has contiguous memory because vector has requirement , array layout compatible native arrays, no padding or may in middle.

note vector<vector<float>> not have contiguous memory, because each vector has additional fields.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
