C :: Every Possible Combination Of A Set Of Numbers
Jul 8, 2014
This part of the code i suppose to get generate all possible combination of number and numbers and combination can't repeat. There 6 set of numbers the first 5 can't repeat, here is what I have so far. Its not efficient and is time consuming for my PC. probably will take upto 10 minutes to complete.
#include <iostream> // std::cout #include <algorithm> // std::next_permutation, std::sort int main () { int myints[] = {1,2,3}; std::sort (myints,myints+3); std::cout << "The 3! possible permutations with 3 elements:
[Code] ....
this will result
123 132 213 231 312 321
The question is : If I want to get a permutation combination with range of N
What should i do?
if N = 2 result should be 12,13,21.....such and such
Eliminate the last digit is working for 3 combination but if its going to a bigger number it does not work ...
I have been struggling with this program. I am somewhat new to c and suck at logic. I have a personal program I want to make that I will try to get extra credit for in school. I have a printed set of winning lottery numbers form the last 10 years. I chose the easiest one do do logically which is just 5 numbers none repeating.
I am trying to find out how I can print the least common 10 sets. I think if there are any set which have not been picked I would have to print all of those because logically they would all be equal, then print sequentially the sets least picked up to 10.
I have pseudocode which I am sure is wrong but will post it just to show that I am trying. My first attempt was to add the numbers but quickly realized that that wouldn't work ...

Im about to program a RPG and, of course, the player has got an inventory. The items in this inventory are stored in a linked list and have IDs in form of strings.
player.cpp: (just the most relevant)
#include <list> #include <string> using namespace std;
[Code] ....
Of course, when the player saves the game, the inventory has to be saved too.
game.cpp(just the m. R.) #include <fstream> using namespace std; class CGame{
[Code] .....
Now, in my code I write the linked list into the file savegames.sav
I want to select 1 element from each vector without duplication of any combinations. Essentially only when all combinations are done with 1st element in first vector ,only then it should move to next element in first vector.
Say i have elements :[123] [456] [789]
my combinations should be like 147 148 149 157 158 159 167 168 169 247....
Also, I cant have any repetitions and only after all combinations of 1 are done only then the loop has to move to next combination ie 247 combination and so on.
I tried NCK (n choose k) command but it gave me random combinations. How should i go about it with using minimal for loops?
I want to read a string of unknown length from stdin. I tried to follow the approach from this link.
[URL]....
My code is like this:
Code:
#include <iostream> #include <string> using namespace std; int n; cin >> n; cout << "The value of n is " << n << endl; string str; getline(cin, str); cout << "The entereed string is " << str << endl;
What I have noticed is that if I take integer input from cin (cin >> n in the above code before getline, the control does not stop on getline to take str as input from the console. If I don't do (cin >> n) before getline then the control stops on getline and takes the string as input.
What is the best way to read from console multiple strings of unknown length in combination with the integers?
User enters sentence "The Smiths have two daughters, three sons, two cats and one dog." (The numbers may change depending on what the user chooses to enter. He told us the range would be from zero to nine.) and we have to convert the written numbers within the sentence into actual decimal numbers and print out the new sentence. Ex. The Smiths have 2 daughters, 3 sons...etc.
I have written the following bit of code which reads the string and finds all the "written numbers" but I am not sure how to proceed from there. I am stuck on how to print out the new sentence with the converted numbers as my professor mentioned something about creating the new string using dynamic memory allocation.
Code: #include <stdio.h>#include <string.h> int main () { char A[100]; int length = 0; int i;
Find all the prime numbers between a given pair of numbers. Numbers should be read in from an input file called "numbers.txt" and find all the prime numbers between them. Store the prime numbers in an array, then sort the array from greatest to least. Display the array before and after the sort.
I'm stuck on how to put the prime numbers into an array.
The input file has the numbers 1 & 100.
Here's what I have so far.
#include <iostream> #include <fstream> using namespace std; int main() { ifstream fin; fin.open("numbers.txt");
I'm working on this program that I have to design a class Numbers that can be used to translate whole numbers to the English description of the number.
Now this is what I got so far:
#include <iostream> #include <string> using namespace std; class Numbers { private: int number; static string ones[]; static string tens[];
[Code] ....
The program seems to work. However its not giving me the right number description,
Example:
Please enter the amount you would like translated into words: 5 six dollars please enter another number: 10 eleven dollars please enter another number: 20 thirty dollars please enter another number: 30 forty dollars please enter another number: 100 two hundred dollars please enter another number: 150 two hundred sixty dollars please enter another number: 500 six hundred dollars please enter another number: 1000 two thousand dollars please enter another number:
The code below will generate combinations of numbers from 1 to 25 in an 15 numbers array. The only filter I've applied is that the sum of all the numbers in the vectors divided by 15 needs to be between 13 and 14. I would like to count how many consecutive numbers there are in one combination, so that later i can apply another filter.. for example:
I want to make a program to print the product of even numbers between 1 and 30 and sum of odd numbers between 1 and 30. But the answer of product is negative. The photo shows the output of the code.
#include <stdio.h> #include <conio.h> void main () { int i, even_product=1, odd_sum=0; for(i=1;i<=30;i++) // For loop starts here!
So i have made an array and made a scanf in a for loop so it can store all numbers entered from keyboard in the array but i dont know how to put the numbers that are less than 5 in another array and then print that array out and the lenght of the array.
I wrote a program which sends a starting and ending range to other processes and the processes calculate the prime numbers in that range and return the count of prime numbers to the head process, process 0. But this is not working properly at the moment. I realize I still have to split up the range based on how many processes I have...I still have not figured out how I want to set that up. I
Code:
#include <stdio.h> #include <stdlib.h> #include <mpi.h> int isPrime(int num); int main(int argc, char **argv){ }
Write a program which reads a stream of numbers from a file, and writes only the positive numbers to a second file. The user should be prompted to enter the names of both the input file and output file in main(), and then main() will open both files. Another function named process() must then be called to read all the numbers from the input file and write the positive numbers to the output file. Note that you must pass the open stream variables for each file as arguments to the process() function, and that you need to (always) double check that the files opened successfully before using them.
This is what I have so far but its not working out!
#include <iostream> #include <fstream> #include <stdlib.h> using namespace std; int process(ifstream &inf, ofstream &outf);
i have trouble with comparing two of the biggest numbers out of four numbers. Im working on an assigment with a dice game where i need to tell the computer the following;
"if the biggest number out of dice_three and dice_four is the same number as the biggest of dice_two and dice_one, then loop1=true"
this is how i have been writing it so far ;
if (MAXA(dice_three,dice_four) == MAX(dice_two,dice_one)){ lopp 1=true; }
If I have the number 88 how would I add 00 to the end of and turn it into 8800? Bitwise shifts is the only way I can think of to do this but it doesn't work. It completely changes the numbers.
Design an algorithm using flowchart to prompt the user for 5 values. Total up all these values and print the total at the end of the program. If the number is equal to zero the system will terminate.
