Having trouble in c# fraction calculator -


i have assignment due tomorrow has add , subtract fractions whole numbers, , i'm getting bit confused these numbers, , math isn't helping either.

it's performing math correctly, keeps putting 1 whole variable when should 0 , can't figure out life of me why.

here's fraction.cs:

class fraction {     int num, den, whole, newnum;      public fraction(int numerator, int denominator, int whole = 0)     {          this.num = numerator;         this.den = denominator;         this.whole = whole;     }      public fraction add(fraction other)     {         int temp1 = num, temp2 = den;         if (math.abs(this.whole) > 0)         {             newnum = temp2 * whole;             newnum = +temp1;             temp1 = newnum;         }         if (math.abs(other.whole) > 0)         {             other.newnum = other.den * other.whole;             other.newnum = +other.num;             other.num = other.newnum;         }         temp1 = temp1 * other.den + temp2 * other.num;         temp2 = temp2 * other.den;         if (temp1 == temp2 || temp1 > temp2)         {             whole = temp1 / temp2;             temp1 = temp1 % temp2;         }          fraction newfrac = new fraction(temp1, temp2, whole);         return newfrac;     } }

and inside program.cs here's test:

fraction fra1 = new fraction(1, 2); fraction fra2 = new fraction(3, 4, 1); fraction fra3 = fra1.add(fra2); console.writeline("fraction 1: " + fra1); console.writeline("fraction 2: " + fra2); console.writeline("{0} + {1} = {2}", fra1, fra2, fra3);

and here's i'm getting result:

any appreciated! in advanced. austen

i think problem line:

whole = temp1 / temp2

it seems you're accidently modifying whole value of current instance. that's what's causing fra1 'magically' change 1/2 1 1/2. use temporary variable instead , should fix problem, i'd recommend making similar adjustments avoid accidentally modifying fields of other removing newnum field apparently there temporary placeholder calculations.

if intend make class immutable, i'd recommend making each of fields readonly avoid these errors.

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
