But it is scrappy. The visitor classes had to be placed outside the classes they belonged to, and CountB lost its template because of that. Also, it is very awkward that I have to construct a "reverse hierarchy" for the Visitor classes (which means that this has to bechanged if I ever change the hierarchy for A, B, C, ...). How to improve my solution (using acyclic visitor pattern)? Forward declaring nested classes is not possible in c++.
Is there an algorithm in the STL to move elements similar to how std::copy works? I have read various places that the new C++ standard has a move algorithm. Unfortunately the compiler I use (g++ (GCC) 4.2.0) does not support any C++0x updates.
I have a std::deque that I want to move a range from into an array. I am currently using something like this where
data_array is an unsigned char pointer to a buffer being passed in by the caller dataQ is a std::deque<unsigned char> that is a member variable maintained within the class
Code: for (int i = 0; i < numberBytesRequested; ++i) { data_array[i] = dataQ.front(); dataQ.pop_front(); }
I'm concerned that executing this loop over and over again is going to be very inefficient.
I need to make singly and doubly linked list classes that can insert elements. Once the lists are created, I need to order the linked list elements according to a certain pattern.
In this program what i'm doing is to search for a number when the vector is in order, and count how many times that number appears, the problem is that count how many times the number does not appear, but when its appear the program stays in an "standby mode" and the cursor does not move.
int buscarNumOrdenado (int x [MAX]) //MAX is the define { int num,d, LimiteInferior, LimiteSuperior,mitad; d=0; LimiteInferior = 0; LimiteSuperior = MAX-1;
I'm running a game online and designing a program to generate Enemy Stats. Basically, it's supposed to generate 25 numbers between 0 and 7(to represent 8 Attributes on a 25 Point Buy system) and count how many times each number shows up.
Here's what the code looks like:
Code: #include <iostream> #include <ctime> #include <cstdlib> using namespace std; int Generate() { int r= rand(); int s= r%7; [Code] ....
The following fuction from a class is supposed to count the number less then the average of all number combined. but it does not do that, now the fun part if you change it to count the number greater then the average it works great.
void IntegerArray::countBelowAverage() { avrg=calcAverage(avg); int count=0; for(int x=0; x<100; x++) { if (list[x]<avrg)
How can I define type MARKS which will be able to hold 4 elements just like array? I want to access it just like normal array elements using brackets []. In the following struct I want to use such type.
Purpose of the struct ARGUMENTS is to hold 4 pointers to string. I want to mark few positions in string so I can simple access them. E.g. name=John
Code: arguments[0][0]=0; // begin of the param name arguments[0][1]=3; // end of the param name arguments[0][2]=5; // begin of the value arguments[0][3]=8; // end of the value I mean not to save int but the pointer to the corresponding position.
I want to use a dataset of type set which will have the type pair<char,string> or pair<string,string>. How can i insert values into the set, because i have to initialize the set and will not change the set during the program.
"Write a declaration for a function that takes two int parameters and returns an int, and declare a vector whose elements have this function pointer type."
4.1 Write a program that will count from 1 to 12 and print the count, and its square, for each count.
4.2 Write a program that counts from 1 to 12 and prints the count and its inversion to 5 decimal places for each count. This will require a floating point number.
4.3 Write a program that will count from 1 to 100 and print only those values between 32 and 39, one to a line. Use the incrementing operator for this program.
i am writing a program that accepts a decimal number from the user and convert it to binary numbers. After the conversion, i should count the number of 1's and 0's in the said binary number. I got upto converting and counting 1's using Brian Kernighan’s Algorithm. But, i can't seem to get it to count the number of 0's.
#include <iostream> #include<bitset> using namespace std; int main() { int num,count=0,Zero,count1 =0; cout<<"Enter the number:"; cin>>num; string binary;
I was wondering how to limit error message to one only.
For example
cin.getline(stringname,7); for(int i=0;i<size;i++){ if(strcmp(stringname, "hello")=0) cout<<"Found!"<<endl; else cout<<"not found"<<endl; } not found not found .......
I want to count number of words from my textfile and then make the first word ToUpper and second word ToLower and do that for the rest of the textfile.
using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; using System.IO; namespace ConsoleApplication3 { internal class Program { private static void Main(string[] args) {
I want know if the query returned zero rows or not.
Don't want to use count(*)
sql = "select * from TABLE where employeefirstname = @First order by EmploymentStatusDescription"; using (SqlCommand cmd = new SqlCommand(sql, conn)) { cmd.Parameters.AddWithValue("@First", First); reader = cmd.ExecuteReader(); } while (reader.Read())
In above XMl if you check the ParentProductCat is prefixed with ns1:,ns2:,ns3:....
My XSLT code only checkes for the ParentProductCat but since it is prefixed with "ns*:" (* is integer) it fails to find it. So that in C# code replace function is used to replace ns*: a for loop is used for this and it goes until 1000
But now my response crossed the 1000 mark and this time the XML contains total 14500 lines.So I want to replace all ns:*
For this I want to count the number of lines present in the XML so that the for loop will run until that line number. how to do that?
