caching - cloudfront cache hits only pricing -


lets using aws's s3 connected cloudfront .

and s3 sends 1 image file of size 1 mb cached on cloudfront's edge nodes.

then cached image file downloaded 1 million times cloudfront's edges .(the image not grabbed again s3 ).

do pay

1-the bandwidth transferring file s3 cloudfront edges.

2- bandwidth transferring file s3 cloudfront edges + bandwidth 1 million downloads cloudfront edges .

also , if answer 2 , means caching doesn't save money @ ? impove performance ?

and if that's case why use cloudfront instead of cloudflare since cloudflare provides free bandwidth ? (is there catch there ?)

you don't pay s3 cloudfront:

if using aws origin, effective december 1, 2014, data transferred origin edge locations (amazon cloudfront "origin fetches") free of charge.

you pay outbound transfer. if stay lowest-priced cloudfront tier, you'll pay $85 data plus 75 cents http requests.

in comparison, using s3, ignoring free transfer tier, you'll pay $90 data plus 40 cents http requests.

so, why use cloudfront? first, users lower latency download 1mb file. second, price remains lower go bandwidth tiers- if shipping 300tb of data per month, final tier 20% cheaper s3 price.

there places offer better bandwidth pricing aws, in server/file/cache variations. if use cloudflare you'll pay s3 cloudflare. may need pay once (1mb), in reality it'll more once.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
