1's complement using ~ in C/C++ -


i using visual studio 2013.
tried ~ operator 1's complement:

int = 10; cout << ~a << endl;

output -11

but for

unsigned int = 10; cout << ~a << endl;

the output 4294967296

i don't why output -11 in case of signed int. please me confusion.

when put number 10 32-bit signed or unsigned integer, get

0000 0000  0000 0000  0000 0000  0000 1010

when negate it, get

1111 1111  1111 1111  1111 1111  1111 0101

these 32 bits mean 4294967285 unsigned integer, or -11 signed integer (your computer represents negative integers two's complement). can mean 32-bit floating point number or 4 8-bit characters.

bits don't have "absolute" meaning. can represent anything, depending on how "look" @ them (which type have).

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
