I have a dataset which is a coauthorship network (a .txt file).I want to replace all the names of the authors with a unique number(no matter what the number is but it's important these numbers should be unique).
I've opened the dataset in excel then copy the author's names to another excel file,then I want to replace the authors names with their row numbers. what should i do?
Is there a way of using a rand-function in a way that it seeds the same random numbers every time the function is used? I'm looking fomr something like:
int * randfunction(hash maybe){
//Fancy code...
return // quasi random numbers, same each time function is used.
}
I'm testing an algorithm where I need a set of unique random numbers. So far I've only used hard coded numbers on small scale test runs. I'd like to do the up scaling, but haven't really figured out how to seed random numbers like I need to.
Here is what I'm trying to accomplish (it is a rather simple program): A classroom of students are to grade a certain number of other exams. The exams should be distributed equally and RANDOMLY, every student should receive the same number of exams, and no student should receive their own exam to grade. The only problem I have is to generate unique random exams for each student. Right now, I have it set to where each exam is distributed the same number of times, every student gets the same number of exams to grade, and no one gets there own. However, I don't have any parameters that prevent one student from getting the same exam multiple time.
Here is an example output:
Student 1 will grade: 4 3 2 5 <- CORRECT OUTPUT (no exam appears more than once)
Student 2 will grade: 5 5 5 1 <- exam 5 appears three times
Student 3 will grade: 4 2 2 2 <- exam 2 appears three times
Student 4 will grade: 3 3 1 1 <- exams 3 and 1 each appear twice
Student 5 will grade: 1 3 4 4 <- exam 4 appears twice
(each exam appears four times and every student is assigned four exams. no one gets their own)
Here is my code (area of problem is close to the bottom):
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
void create_class (int);
int main (void) {
srand(time(NULL));
[Code] ....
I tried keeping the exams for each student in the array exam and then checking each one every time I generate a number, but that didn't work.
We had to generate random, unique numbers in the range [1,15]. But running the program for several times showed a bug: It wouldn't always generate a new number for every repeated number. I can't figure out the problem, especially since it works half the time and I can't figure out what's making it work some times and not others.
bool flag1 = true, flag2 = true, flag3 = true;
int i, j = 1;
int[] A = new int[11];
Random rnd = new Random();
A[0] = rnd.Next(1, 15);
Console.WriteLine("1. = " + A[0]);
[Code] .....
Below is my code for a program that is suppose to generate and display six unique random numbers (between 1 and 54). The issue seems to be in my check for duplicates. I know what I am doing wrong but can't seem to find a way to fix it. I think it is getting stuck in an endless loop because the way I have written it looks like it checks the first value against itself which will of course look like a duplicate everytime.
Code:
#include<iostream>
#include<ctime>
using namespace std;
//function prototype

I have to create a template to look like this: template<>....with a class inside the arrows. Then, I have to use bubble sort to sort the 5 names and number objects I have created. Sorting the names and numbers and also using templates?
Can names and numbers be stored in one array ? Like a telephone directory?
View 1 Replies View RelatedI am trying to write a program that would convert numbers of base 10, decimal numbers, to binary or hexidecimal numbers, base 2 and base 16. I want the program to run a loop through the various numbers input and store each number converted to the new type in a separate variable with the same basic name but different last letters/digits to differentiate between them and add them to the total.
Basically, I'm saying that i have the user input a number and letters. Let's say 15, d, b. So they want to convert 15 of decimal type to binary.
The program would then take the variable used to hold that number, and the other to variables to decide what function to perform on the number.
Then I will already have a variable initialized for the 3 possible conversions (binaryKey[], decimalKey[], hexideciKey[])
Then I want it to convert it and store the number at different places in the array to form the final number. Although, there is no way to predict what number the user will input, so there is no way of knowing initially where the converted place-value will need to be placed in the array.
I was wondering if there was a way to have the program run a loop where as the progression continues, it appends a number to the end of a universal name for the variables and then adds them together in the correct order creating the sequence that means that number.
In simpler terms:
Input a number: 15
Input type of base: d
Input converted type: b
Program then continually divides the number by 2, storing the remainder in a new variable
Such as: for(int i=1, i < (str(number).len), i++){
when i = 1, you would get
int number1;
[Code] ....
and so on. Is there a way to do this???
i have a vector of stores. i would like to delete the specified choice(store) from the list. Here is what i have but my erase statement is wrong and wont compile.

I have a question about an issue I am having on my final project.

Alright I hav a program that readings from a txt file but is there a way to replace some of the words that get loaded into the vector so for example if the txt has a list of animals and i want to replace the word bird for book is their a way to do that
#include <iostream>
#include <string>
#include <vector>
#include <fstream>
[Code]....
I heard that const shall be preferred over #define . So I start to change my program accordingly.
But then below error message occurs during compilation:
#include "common.h"
#include "definition.h"
#include "particle.h"
int main() {
Particle *p = new Particle();
[Code] .....
I guess the error occurs because, when the line 9 of particle.h (File 4) is compiled, value of const int dimension is not seen by the compiler.
i'm trying to replace letters in a word...here's the code so far
#include <algorithm>
#include <iostream>
#include <string>
using namespace std;
int main (){
string s;

The problem is if i type "nm" i'm not getting "mn" as the output, it's "mm"
I'm not trying to swap letters between them
Take this string for an example, "asdf 9.000 1.232 9.00 23.1 545.3"..Is there a way to replace any of the doubles with another double? Example: Replace the first "9.000" with a "10.0". I am aware that string::replace will do the trick, but how do I make it work for arbitrary cases? By arbitrary I mean that I don't know the size of the string to be replaced, I just want to be able to replace any number with a given number.
View 1 Replies View RelatedI'm writing a function that accepts a char array containing the title of a book as parameter, the following then has to take place:
1.) Extra white spaces between words need to be removed [DONE]
2.) Text has to be converted to title case, i.e each new word has to start with a capital letter [DONE]
3.) Lastly I have I text file (minors.txt) containing a number of words that should not be capitalized by the function, like "a" and "an", however I don't know how to implement this.
Example of end product:
ENTER THE TITLE OF THE BOOK: a brief hisTOry OF everyTHING
Correct Output:
bool Book :: convertToTitleCase(char* inTitle) {
int length = strlen(inTitle);
bool thisWordCapped = false;
//Convert paramater to lower case and
//Remove multiple white spaces
for (int x = 0; x < length; x++)

I was thinking of maby reading the words in the text file into a string array, and then comparing the two arrays to ensure that when a word is present in a text file, the word is not capitalized, however I don't know if that is possible between a string array and a char array.
I'm making a hangman game. All i need to do is after the user guesses the letter correctly it replaces the stars with that letter. I have been trying for the past 2 hours and cant get it. So basically I have to do this. DisplayWord.replace(0, theWord(0)) but I don't know how to put it in.

I am working on a parking lot scenario project using multidimensional arrays. The parking lot has 8 rows and 10 parking spaces in each row. Altogether there are suppose to be 30 cars parking in the lot and arrive in numerical order. I am suppose to generate a random number to represent the row and another to represent the space in the row.
The problem I have is that a few of the elements are being replaced. The project requires the car to check if the space is taken, if so it is to find another one. Here is what I have...
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW 8
#define COL 10
#define CARS 30
void parkTheCars(int result[ROW][COL]);
void displayArray (int result[ROW][COL]);

I have a Win32 C++ application which works pretty well, but I don't like the GUI and I want to replace it with one designed graphically, a la Windows Forms. What is the best strategy to port my code? I tried creating a new Windows Forms C++ application and got pretty far with it, but was stymied when trying to call my unmanaged functions on a button press. If I can't use Forms to add a GUI without completely rewriting the program, what's my best bet?

This function should replace all instances of a character in a given character array, while returning the amount of characters changed, but I keep getting a segmentation fault at the highlighted area.
I'm only supposed to use pointers so arrays are out of the question, and I don't think we are allowed to use the string.h library as well. How I could avoid something the segmentation fault or ways to fix it?
Code:
int replaceChars(char replace, char find, char *input) { int i, j;
//Finds length
for(i = 0; *(input + (i + 1)) != ' '; i++);
int c = 0;
for(j = 0; j <= i; j++) {
if(*(input + j) == find) {
*(input + j) = replace; //Segmentation fault happens here
c++;
} }
return c;
}
I'm trying to right the function that puts the correct letters in the right positons being reported from my previous compareletter function for my game of hang man and its not updating the word in progress array. Here's my compare letter function that's working correctly:
Code: //function that returns the index of the letter that the user has guessed or Code: //-1 if the letter isn't in the word
int CompareLetter(char array[], char guess, int numLetters)
{
int i;

However, this isn't changing any of the position of the asterisks in the word in progress array positions 0-3.
Code for c programming reads and compress each row of the array by replacing each character with a single character and the number of times it occurs?
