i have base class named variable: class variable { protected: std::string name; public: variable(std::string name=""); variable (const variable& other); virtual ~variable(){}; }; i have several derived classes, such int, bool, string etc. example: class bool: public variable{ private: bool value; public: bool(std::string name, bool num); ~bool(); bool (const bool& other); bool getval(); each derived class has method named getval() returns different type (bool, int, etc.). want allow polymorphic behavior variable class. tried: void getval(); seemed wrong , compiler showed error: shadows variable::getval() sounds bad. thought of using template <typename t> t getval(); didn't help. any suggestions? have use casting that? many thanks... you can't overload return type . think template work better in case. there's no need polymorphism or inheritance here: template<class t> class v

i'm trying solve recurrence t(n) = t(n/8) + t(n/2) + t(n/4) . i thought idea first try recurrence tree method, , use guess substitution method. for tree, since no work being done @ non-leaves levels, thought ignore that, tried come upper bound on # of leaves since that's thing that's relevant here. i considered height of tree taking longest path through t(n/2) , yields height of log2(n) . assume tree complete, levels filled (ie. have 3t(n/2)) , , have 3^i nodes @ each level, , n^(log2(3)) leaves. t(n) o(n^log2(3)) . unfortunately think unreasonable upper bound, think i've made bit high... advice on how tackle this? one trick can use here rewriting recurrence in terms of variable. let's suppose write n = 2 k . recurrence simplifies to t(2 k ) = t(2 k-3 ) + t(2 k-2 ) + t(2 k-1 ). let's let s(k) = t(2 k ). means can rewrite recurrence as s(k) = s(k-3) + s(k-2) + s(k-1). let's assume base cases s(0) = s(1) = s(2) = 1, s

let's there square 2 dimensional array of n x n, represented 1 dimension array. let array 5x5, below, , values in array not significant. std::vector< int > array { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4 }; if there 5 rows , 5 columns in array, how can 1 detect if on edge of row? instance, if on index of 9 on 4th row, how can know can go left without changing rows, going right advance next row? how can 1 access cell's neighbors respect edges? index of 9 on 4th row not have right neighbor. the way can think of how current index, in case is int index = row * num_cols + col and perhaps use modulus (index % 5 == 0) determine if on edge. not determine if can go left or right. your formula int index = row * num_cols + col; going or down equivalent adding / subtracting num_cols . is correct. reverse of is int row = index / num_cols; int col = index % num_cols; you know you're on left edge

suppose have following code. while debugging, want eclipse stop when has done 1 million iterations. how this? cannot manually 1 million times. for(int = 0; < 10000000; i++) { //some code } you can put conditional break point in eclipse: put breakpoint right-click->properties turn on "condition" check-box put condition code i == 1000000

i'm pretty new assembly. know how take in 1 value user, if want user input 3 numbers separated spaces. i'm trying store each of them separate register, this. push qword 0 ;make space 8-byte number push qword 0 ;make space 8-byte number push qword 0 ;make space 8-byte number mov qword rdi, formatfloatinput mov qword rsi, rsp mov qword rax, 0 call scanf pop qword r15 ;pop value stack r15 pop qword r14 ;pop next value in stack r14? pop qword r13 ;pop next value in stack r13? sample input: 13 15 36 now r15 should contain 13, r14 contains 15 , r13 contains 36. the c equivalent scanf("%ld %ld %ld&quo

i'm developping plugin winphone 8 unity3d using c++ , directx. i'm right stuck because don't know how pass intptr type c# code c++ code. it's easier android or ios plugin since can data void*. in windows phone runtime component project it's not possible. read i've got use winrt types. i've search here code samples: in c#: public delegate void wp8enabletexturedrawing(system.intptr texture); private wp8enabletexturedrawing wp8enabletexturedrawing; public void setwp8texturedrawingfunc(wp8enabletexturedrawing func){ wp8enabletexturedrawing = func; } //... wp8enabletexturedrawing(targettexture.getnativetextureptr()); in c++ header file matches delegate way: static void enabletexturedrawing(platform::object ^textureptr); but compiler throws error -> no overload 'wp8texturedrawing.texturedrawing.enabletexturedra wing(object)' matches delegate 'nativetexturedrawer.wp8enabletexturedrawing' i hope has hands in me out. th

the program should ask whole number before printing anything. program must check input numbers between 0 , 5. fail if number of digits entered other 5. failed input can terminate program appropriate error message. inputted numbers may duplicates. (ex. 3, 3, 3, 0, 0 acceptable input.) need getting program print out '.' if input=0. , asking 5 digits @ same time. nums[] nums= input number=int(input) n in number: if n<0 , n>=5 , if len(n)=5: print 'x'*n elif n==0 , if len(n)==5: print '.' elif n>0 or n<5 or len(n)!=5: print "invalid input" your program bit messed up.. forgive me if i'm being little rough first, isn't allowed: nums[] second, number = int(input) is invalid, because input not valid number. third, for n in number number integer, not list! fourth, if number list: len(n) ==5: will still invalid, because n integer! try this: input_list = raw_input("
