c++ - Postfix LL for type long long -


this basic.

while defining type long long expression like.

long long x=5435666ll;

i cant understand why ll post fixed since without post-fix quite clear compiler allocate right memory space(8 bytes in vc++) anyways in absence of post-fix.

so purpose 'll' post-fix serves?

your code equivalent to

long long x; x = 5435666ll

without ll suffix, 5435666 int. in either case result same because 5435666 fits in int, unless you're on 16 bit platform.

matlab - How to equate a structure array to structure array -

the following code doesn't work, think it's clear want do: my.struct = 1; foo.bar = my.struct; so that foo.bar.struct = 1 basically want fill in my structure array bunch of fields , values. want place struct nested struct within foo.bar while retaining field names. my.struct = 1; foo.bar = my.struct; this places value of my.struct (= 1 ) in foo.bar . of course foo.bar 1 . i think you're after this: my.struct = 1 foo.bar = my;
