Using a regular string as a code for compiling -


i need make function receives string such as:

int *ptr[20], *p, p2, p3[3];

and function need print:

ptr requires 80 bytes. p requires 4 bytes. p2 requires 4 bytes. p3 requires 12 bytes.

to simplify task, use "fake" code in string "real" code, , print function sizeof(variable) answer question. think simple way. how it?

what describe ability "evaluate" dynamically generated code.

some languages -- evaluated (non-compiled) ones -- have such features, c++ not.

even if did, wouldn't solution here. need parser. formal approach, may research lexers , context-free parsers. ad hoc approach...well...do whatever string manipulation like.

(all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
