typedef client...I would like to have these fields filled with this function below and stored in an array... Basically Multiple users and this is my function for it, if I can get it to work proper -.- .... I don't get syntax errors but I do get warnings
Code:
void getct(client *cl, int *pclientCounter) {
char input[buff];
char *pinput = NULL;
int typef = 0;
int lengthf = 0;
}
struct Wine { string wineName; int vintage; int rating; double price; };
how can i store the file data below in an array with the structure type???

template <typename T> struct avl_tree { T data; int balance; struct avl_tree <T> *Link[2]; static int (*comp)(T, T); };
In main, I have a function like so: int compare(int a, int b) { return ( a - b ); }
Now how do I assign the function pointer in my avl_tree class to the compare function?
I did this: int (avl_tree<int>::*comp)(int, int) = compare;
But I got the compiler error: Tree_Test.cc: In function ‘int main()’: Tree_Test.cc:27:42: error: cannot convert ‘int (*)(int, int)’ to ‘int (avl_tree<int>::*)(int, int)’ in initialization
I'm having trouble reading my data from a .txt file into a structure of the format shown in my code. I've made my student database in the program below based on user input and I didn't have a problem with that, but now it's come to input from a file it's making it difficult.
My three tasks are:
(1) A table containing 1 row per student, containing the student ID number and all of the student's marks.
(2) Another table, containing 1 row per student, containing the student ID number and the average mark obtained by that student.
(3) The average mark for each subject.
The assumptions to be made are: The student ID can begin with a zero, and should therefore be read in as a string.The test data will contain 20 students but the program should be able to deal with up to 100 students.Assume there are no more than 4 different subjects.
So based on the first assumption I've arranged the data in the file in an order in which the student ID begins with a zero:
...for twenty students, 80 lines of data. Now, on the assumption they must be read in as strings, this is what's making it tricky to store in the structure because, I've got 80 ID numbers but 20 repeat themselves 4 times. Once I've got this data in the structure below the tasks I won't have a problem with because I can just base it on a user input program but the data's already stored instead.
Below is my code for user input associated with task (1). In this example the IDs are stored as ints but for the file they will be strings. It compiles fine, displays the data as shown in the assignment sheet, but I don't know how to get the data into my structure. I can store the data in a structure of three arrays using fscanf() no problem, but it's not very "workable" for what I need to do with it.
#include <stdio.h> int main(void) { //2D Array int array[2][2]; int number = 1; }
[code]....
The array is not filled incorrectly for some reason, more specifically the first row.The first two cycles of the for loop seem to work correctly. One if the bugs seems to occur on the third. when array[0][2] is filled with number 7, for some reason array[1][0] changes it value to 7 as well.
Code: int arr2d[rows][columns] ; // Not valid syntax of course ... let be arr2d rows * columns size for(int i=0; i<rows; i++) for(int j=0; j<columns; j++) arr2d[rows][columns] = some_value;
What is the complexity? I believe O(n) and not O(n^2) on this case because if you have 3*3 size you would put 9 elements (from 9 elements input of course)... for each input you have one insertion and that is the meaning. Same as 4*4 size 16 input times 16 insertions .. or 5*5 and so forth...
I am trying to make kind of a messenger using Socket/Network Programming
My program should allow clients to register or sign in, after they are signed in they should see a list of the other signed in people whoever I select from that list I should be able to implement using multiple threads as well.
I am currently working on writing a word search program. However, I am stuck on reading the used input into the 2-D array. The code I've posted below is only dealing with the user input (I'll work on the word search part once I know i am correctly reading in the user input). I know the coding is bad practice with the use of hexadecimal, and getchar() ect. But I am currently using a microblaze microprocessor and this is just the way microblaze can interpret the information. As for the infinite while loops...that can be changed just trying to figure out how.
My question is how could I change my code to correctly read in the user input into the 2-D array?
Code: #include "platform.h"#include "xparameters.h" #include <stdlib.h> #include <stdio.h> #define MAX 20 int main() { char grid[MAX][MAX], word[30]; int i, j, arr[2],num;
Just trying to fill a dynamically allocated array with values then I want to print out the values using pointer method:
#include <iostream> using namespace std; long * extend_arr(long int arr[], long int length, long int val) { long * array2 = new long [length + 1]; for (int J = 0; J < length; ++J) array2[J] = arr[J];
[Code] ....
When this runs, I get an array with random numbers in it. For example, just trying to print the first value in *Block gives me random numbers each time. What is wrong with this as to why it is not holding the right values?
The extend_arr works perfectly fine, because when I try to access the values in the array using indexes (arr[0], arr[1], etc) it shows the right output, but using pointers does not. How can I make it work?
int firstarray[12][7] = { }; double firstClass(int airplane, int seats, double price) {cout<<setw(60)<<"---------------------... cout<<setw(60)<<"You are in **first class** booking screen

The thing is, The first 2 rows having 7 columns like this:
0000000 0000000
User gives an input of seats reserved, for example user inputs 3 seats, then the program should give output like:
1110000 0000000
I will not ask any specific seat but put assign seats randomly where available.. How to do it?
I am trying to fill an array with blank spaces and instead i get the number 32 over and over, i think this is the ANSI code for that character. how do i get the character itself?
I wrote a Simon game, and wanted to save the top 10 scores. I was working right, until I decided I wanted to still be able to read the file if someone enters a name containing spaces. Now, the results aren't right.
void FillScoreList(string Simon_Names[], int Simon_Scores[]) { ifstream Simon_HiScores("Simon_Data.txt");
if (Simon_HiScores.is_open()) { for( int x=0;x<10;x++){
[Code] ....
Even without trying to read names with spaces, I'm getting
dad 1 0 340176 0 ... either a long number or a zero. No names
#include <iostream> #include<fstream> int decryption(int); int multiply(int,int[][2]); using namespace std; main(){ int n; ifstream inFile; inFile.open ("out.txt");

I was trying to store numbers read from a text file into 2D array but I am getting the error above.here is where the error occurs:
I have a base class Building. Then come its children classes - Commercial Building and Residential Building. The third level is composed of Apartment and House classes, both inherit from Residential Building.
I need to create an array of 20 elements that will store info about all these different types of buildings(Commercial Building,Residential Building,Apartment, House). How should I proceed?
I want to create filenames such as Query.student.1.bin and save them in an array. I have no problem when I don't include a "." between student and number "1" but as I add a "." there my code does not run. ( it does complie but crashes during the run)
for(int i = 0 ; i < SIZE ; i ++) { scanf("%d" , & selection[i]); srand((unsigned) time(&t)); draw[i] = rand() % 50; //feeling could be a problem with this line of code :::::
}
is it possible to do this. i am trying to get 6 different numbers stored into 6 elements of an array . this is the piece of the code i think there is a problem with. ie my program scans the numbers and then crashes at this point so think it could be something to do with the commented line?
