I have two std::sets S1 and S2 which I need to merge.
I know that the largest element of S1 is less than the smallest element of S2.
the additional information about S1 and S2 should enable me to do the insertion of each element in costant time instead of log(N).
what is the fastest way to calculate the union of the two sets?
How can I declare a set of strings that i want to be ordered by a boolean function Comp? Like the one you would write in
sort(v.begin(), v.end(), comp);
I tried
set<string, Comp> S;
but it doesn't work
And the same question for priority queues, can you specify the function you want your elements to be sorted by?
I have a vector of sets in which I wish to remove a set from the vector, if it contains a certain value, is there any way of doing this?
for(int j = 0; j <= clauseVector.size(); ++j){
if(clauseVector[j].find(find) != clauseVector[j].end())
std::cout << "FOUND: " << propagator << "
";
}
}
This is what I have been using to find the element, but is there a way to remove the set that contains the element?
If needed I can include the full code
Night now I'm working on part of a function that scans in two sets of coordinates. Is there a way I can scan both sets of coordinates in with the same scanf?
ex. scanf("%d%d%d%d," &destroyer_1, &destroyer_2, &destroyer_3, &destroyer_4)
but that didn't work...
Code:
printf("What are the first coordinates for destroyer:
");
scanf_s("%d%d", &destroyer_1, &destroyer_2);
gameboard[destroyer_1][destroyer_2] = 'd';
printf("What are the second coordinates for destroyer:

Ok so I am currently trying to add and subtract two sets of integer arrays. When I run my program, the program does not subtract the numbers from the first set with the numbers from the second set. Could anyone here take a look at my code and help me figure out what the problem is?
#include <iostream>
#include "SafeArray.h"
using namespace std;
[Code].....
I have a vector of sets, which I am removing any element which contains a certain value. For example, if I was looking for 2:
[0] 1 2 3
[1] 4 5 6
After the program was run, I would be left with just [0]4 5 6.
This is the code I have been using
auto iter = std::remove_if( clauseVector.begin(), clauseVector.end(),[propagator] ( const std::set<int>& i ){
return i.find(propagator) != i.end() ; } ) ;
clauseVector.erase( iter, clauseVector.end() ) ;
I want to know, is there any way I can tweak this code so that it only removes one part of the set rather than the whole thing. For example with above example, I would be left with
[0] 1 3
[1] 4 5 6
So I'm attempting to write a program that will parse through a large file (genome sequences) and I'm basically wondering what options I should consider if I wanted to either:
a) store the entire genome in memory and then parse through it
b) parse through a file in small portions
If I go with "a", should I just read a file into a vector and then parse through it? And if I go with "b" would I just use an input/output stream?
I've recently started to learn C++ and I'm using codeblocks as my IDE, but I keep getting problems with AVG free edition picking up random pieces of code as Trojans ?! I've put an example of some code that sets it off below, and the error message I get. Is there anyway I can set AVG not to trigger with any codeblocks coding I've done? I guess I could tell AVG not to trigger for that folder, if that's even possible?

I have come across a problem lately. You are given a set of n sets with m variables.. for instance {a,b,c,d}, {b,c,d}, {b,c}, {c,e,f}, {e,f}. And you want to eliminate elements from these sets with the restriction that you can only eliminate one item from each set and each item can only be eliminated from one set (i.e. if you've eliminated b from set {a,b,c,d}, then you cannot eliminate it from {b,c,d}). The problem is writing an algorithm which determines the maximum number of elements you can eliminate. And I'm hopelessly stuck... of course, you could backtrack it and determine this number but I feel it could be done more efficiently..
View 2 Replies View RelatedI'm currently writing a program and a portion of it needs to have a function that computes the result of a formula for two sets of inputs. It then has to calculate and display the difference between the two results.
I have code that takes the input from the user and converts it to the type that I need. In this case we are talking about latitudes and longitudes that will be converted to degrees, then to xyz coordinates.

It's crashing around the

If I comment that section out, the code still works. But, I know that portion of the code works to copy text from one file to another! It's actually from the Schildt complete C reference and I have tested it several times on it's own.

i need to write a c++ code which can merge contents of several .txt files into a single file. i used the following code , it works but after merging the result file contains the contents merged twice.I think it over writes the result.I want to do it without using command line.
#include<iostream>
#include<fstream>
using namespace std;
int main()
{
std::ofstream("merge.txt");
system("type *.txt >> merge.txt");
system("pause");
return 0;
}
The directions are to write a program that reads sorted integers from two separate files and merge the contents of the file to an output file (third file). The only standard output will be any errors to be reported and a “FINISHED” statement after all items have been processed.
