I'm trying to write a program that should output, in a tabular form, the name of the algorithm, size of the array, number of comparisons and number of swaps. I am really, really, really bad at arrays and comprehending how to output variables from several. Especially in tabular form />
My questions:
1 - How do I make the array size change from 10 to 100 to 1000?
2 - How do I populate the array's with random non-repeating numbers?
3 - How do I make each algorithm count the # of comparisons and swaps?
4 - How do I return the counted comparisons AND swaps (in one return function??) and then print them?
I'm creating a program to read information about class schedules at my school, reformat the information, and allow the user to search for specific semesters. There are eight fields of information. I'm reading the info from a text file using eight parallel arrays, but I'm having trouble declaring the arrays. I can run this code in one compiler (Dev-C++) with no problems, but I get errors when trying to compile it using Visual Studio stating that arrays must be declared with a constant value. I have a loop to run through the text file, with a counter to increment with each subsequent line, then I create a constant int equal to the counter, and declare the arrays of size equal to the constant int. Here's the section of code in question:
// Counting the number of lines in the text file inFileForLines.open("CIS225HW1DA.txt"); string countLine; int numberOfLines = 0; //Discarding the first line of the text file containing only column headings getline(inFileForLines, countLine);
I am trying sort my Calorie array and day array corresponding to each other but how to start i cant grasp the concept for some reason. I want it to sort by calories in descending order.
So instead of this...
Day: Calories:
1 200 2 500 3 400 4 600 5 100
I want this.....
5 100 1 200 3 400 2 500 4 600
#include <cstdlib> #include <iostream> using namespace std; //Prototypes int getDays(int); void getCal(int*,int); float calcSum(float,int*,int);
I have been tasked with sorting a text file with some numbers in it. For example, there can be 5 numbers in it: 1,2,3, 4, and 5. However, they are out of order (3,2,4,1 and 5). I need the numbers in numerical order. How can you sort the numbers into a new file?
Bubblesorting? I can not use arrays in this program. I have already determined the minimum number in the file.
I am trying to create a program that will read data from a text file into a string. Afterwards I need to sort the data in ascending order and print it. So far my program reads the data but I'm not sure how to go about indexing the array.
Having trouble with homework involving (title). Here is the assignment:Write a program that allows the user to enter 10 numbers from the keyboard. Sort the numbers using any sort routine you wish. The output from your program should be 2 columns of numbers. The left column should be the numbers in the order they were originally entered and the right column should be the sorted list. The columns should be labeled. You will need 2 arrays to accomplish this.
Use separate functions for input, sorting, and printing.So, I have to use separate functions for each of these. I would think it would be easiest to do the input in Main() and then the sorting and printing in another function, but of course since you can't return arrays I am kind of stuck on how I return the new array after sorting. I thought about doing the sorting in Main(), but then I would need to still do the original arrays input in a function and would still run into the same problem.
Here is what I have so far:
Code:
//Cameron Taylor #include <stdio.h> #define MAXARRAY 10 int highLow(int[], int); int print(int[], int[], int); int main (){ int unsorted[MAXARRAY], i, j, temp;
[Code]...
I know it seems simplistic right now, but I am just trying to get it to work first and then go back and beautify it up a bit.
Write a program using user-defined function to merge the contents of two sorted arrays A & B into third array C. Assuming array A is sorted in ascending order, B is sorted in descending order, the resultant array is required to be in ascending order.
Write a function to read and display the contents of names and marks. You then ask the user for a name and using the linear search return the index to the user. If -1 is returned then the name is not in the file. Otherwise write out the name and mark for that student.
Next, sort the arrays, write them out and then ask the user for a name to search for. This time use the binarySearch to return -1 or an index. Display the student's name and mark if found.
void getNames(ifstream& inStream, string names[], int marks[], int numElts); int linearSearch(const string names[], int numElts,string who); int binarySearch(const string names[], int numElts,string who); void selectionSort(string names[], int marks[],int numElts); void displayData(const string names[], const int marks[], int numElts); [Code] ....
Now I have worked up some stuff in parts but I am so lost and confused with these specific requirements: Previous questions asked me to sort out a linear search, a binary search and
LINEAR SEARCH:
int searchList(int list[], int numElems, int value) { int index = 0; // Used as a subscript to search array int position = -1; // To record position of search value bool found = false; // Flag to indicate if value was found
Class programming project where we declare two arrays, a sting array containing the names of the boroughs and an int array which which holds accident number for each borough. The main function calls getNumAccidents() function to fill the array. it then calls findLowest() to learn which borough had the fewest accidents. It should print out the accident numbers for each borough and then out the borough and accident number with the fewest accidents.
I'm able to get the program to kind of work. When I run it everything works fine but I am not able to get the arrays to sort and match up correctly..
#include<iostream> #include<iomanip> #include<string> #include<cstring> using namespace std; class combineSort { public: combineSort() {
I am having some problem with my quick sort problem. My program is supposed to create 5 arrays with 5,10,15,and 20 random integers, respectively. Then it should sort those arrays, where the numbers are bigger or smaller than the middle element in the original array! The program I wrote should do that but, its not! The program just keeps running infinitely!
#include <iostream> #include <cstdlib> using namespace std; void p(int k[],int left, int right) { int i = left, j = right;
I define "Comwords" as a string, but apparently it takes the members as chars, then I can't set strings in a structure equal to the chars.
I see to also be having unknown problems with the ComMAL array and loading it values into another element of the same structure.
How to correct this? I was thinking of casting char elements as strings, but could find no reference in my library book regarding how to do that (lots on casting int's a doubles...)
Code:
int _tmain(int argc, _TCHAR* argv[]) { int comm = 10; int targ = 5; int death; struct AI_WORDS
Using a for loop, construct two 100 element arrays, x and y, such that element i of x stores the value sin(2*pi*i/100)) and the corresponding element of y stores cos((2*pi*i/100)). Print the values stored in the elements of x and y as you calculate them.
I have attempted to solve it but I'm not sure why the value 0 is only being printed, maybe I haven't assigned sin(2i/100)) and cos((2i/100)) to the arrays properly?
Code: #include<stdio.h> #include<stdlib.h> #include<math.h> int main () {
So I'm supposed to create a program that will read off words from a .txt file,and use a function to count the number of vowels in each word and then display the specific vowels and their frequencies. ex. if the word is: butter the output would be:
a:0 e:1 i:0 o:0 u:1
This is what I have so far, but I'm running into some problems.
How I would go about counting lines from a file at the same time as extracting words? I need to know the line number to output what line the word is misspelled on. I tried getline and using sstreams but I could not get it to work.
I now know how to count integers with while loop but I'm not sure how to count the integers with array.
So the question is:
1. program should keep reading integers as long as the integers are within [0,9999] 2. when user typed the integer not between 0 to 9999, the program print out the numbers of integers that were typed.
Sample 3 3 3 9999 9999 -1 You entered 3 3 times. You entered 9999 2 times.
#include <iostream> using namespace std; int main() { int i=-1; int x; int numbers[10000];
#include <windows.h> int main() { int i; int y=6; int x=9; gotoxy(x,y); //gotoxy(x,y) must be the coordinate that the number lies in.
[Code] ...
How to make this program that the output is a number that counts up to infinite (or we say just like a timer but there's no minute just all whole number counting up ) using for loop ? and when the number changes it also change in color ! and the color of a number is according to the color attribute of console output.
I am unsure how to write a function which modifies the content of the 1D character array and counts the number of the vowels. the following is the array that i have.
