BigInteger Problem
I am creating a GUI for class and need help with my program. My program takes 2 big integers and adds them together. First how do I declare my 2 Big Integers and then add them together? I have read the API docs , but still need help. Thanks!
...Code:import java.math.BigInteger; public class Integer { private BigInteger IntegerONE; // both entered as strings from GUI private BigInteger IntegerTWO; -
Sorting a String Array
My assignment is to write a program that accepts up to 10 names and corresponding birthdates. The array will be First name, Last name, and birthdate. Then allow the user to sort the list by first name or last name.
I need help on how to start. I know to use a for loop, but how do I begin the first String array assigned to first name, then last name, and then birthdate.
I am not asking for code, just some direction.... -
How do I reverse this PLEASE?...Code:void ShowArray (char name[MAXNAMES][LISTLENGTH],int x) { int length; for(int i= MAXNAMES-x; i<MAXNAMES; i++) {length= strlen(name[i]); for(int j=0; j<(length); j++) { cout << name[i][j]; } cout << endl; } }Leave a comment:

I need to alphabetically sort from A to Z, but my code is Z to A
My sort algorithm is sorting from Z to A, I need it to be A to Z PLEASE HELP
...Code:void SortArray (char names[MAXNAMES][LISTLENGTH]) { bool swap; int temp[LISTLENGTH]; do { swap=false; for (int i=0; i<MAXNAMES-1; i++) { if (strcmp(names[i],names[i+1])<0) { for (int j=0; j<LISTLENGTH; j++) { -

Selection sort algorithm using strcmp
I need hints for an algorithm using string compare in a selection sort.
I will be sorting lastnames and first namesalphbetica lly. if the selection sort encounters the same last name it then goes to first name and alphabetizes the list.

[QUOTE=Ganon11]All of this sounds good...have you come across any trouble yet?
When you are inputting data, you will have to separate each piece of information from the others. I would suggest making a Person class or struct that you can overload the < operator for - this will help immensely when doing your selection sort. Also, do you have to use selection sort? There are much quicker sorting algorithms out there - one such...Leave a comment:

Converting unsorted info from a file then alphabetically to a new file
I need to open a file that has unsorted list of names and birthdates formated like this: LASTNAME, FIRST$MM/DD/YYYY\n.It could have as much as 100 names. I will use a selection sort algorithm to alphabetize the list and store it in a new file named by the user. So how do I read the data from the file? Then take that information using a selection sort algorithm to alphabetize the list and store it in a new file? I know it's a 2D array
