Even if you do something like resize the frame?

by the way if I haven't said it, thanks for the time,

Curious, cannot resize the frame, and if outside the debugger if I say, start it from a explorer window and press my run button, then touch the explorer window, a few seconds go by and the menu bar disappears but then I can resize the window again.. the symptoms tell me it is a control or messaging issue but I don't know where to look for the problem?

Arbitrary - arithmetic precision

Hello Sir/Madam,

How do I implement arbitrary arithmetic precision in C Programming Language. By using only standard library.

Thanx in advance.

there are links to at least five different libraries which do this, on the first page of that Google search.

Are you even serious? Do you expect someone to explain a possible solution to you in a forum reply like this? WTF | :WTF:

Just take a look at the GNU BigNum library if you need a library that implements it.

I don't need the libraries. I need a function and by using that function I wish to implement that one in my program without using any additional library which is not available in the standard template.

hey i mean with BY USING ONLY STANDARD LIBRARY is that use only header files those are available. Don't use any additional liraries.

Hey, that means you need to write it yourself!

1. You have to write it yourself.
2. From my understanding, this is a very daunting task and therefore there are very few successful implementations so far.
3. This forum is for asking specific queries, so you can do that yourself and come here to ask *specific* queries.

Bubblesort help

Can someone please help me with my bubblesort. It does not seem to sort and also prints 3 times.

#include <stdio.h>
#include <stdlib.h>
#include<time.h>

#define SIZE 6
#define MAX 53

void printArray(int N[], int T);
void fillArray(int N[], int T);

int main()
{
srand(time(NULL));

int PICKED[] = {0,0,0,0,0,0};

fillArray(PICKED, SIZE);
printArray(PICKED, SIZE);

return 0;
}

void fillArray(int N[], int T)
{
for(int P=0; P<T; P++)
{
N[P] = (int) (rand()% 52+1);

for(int y=0; y<P; y++)
{
if(N[y] == N[P])
{
N[P] = (int) (rand()%52 +1);
P=-1;
}
}
}
}

void printArray(int N[], int T)


	{
		for(int P=0; P<SIZE-1; P++)

		{

			if(N[P]>N[P+1])

			{

				int T = N[P+1];

				N[P+1] = N[P];

				N[P] = T;


printf("\nLOTTO PICKS\n");
for(int P=0; P<SIZE; P++)

{
	printf("%d ", N[P]);


printf("\n");

}}}}

First, format your code so that it is easier to read. Use the <pre> tags for this. Second, break your code up into three functions instead of two: fill, sort, and print.

As far as printing, check the two for() loops in printArray().

In the end, you should end up with something resembling:

void fillArray( int N[], int T )
{
    for (int P = 0; P < T; P++)
        N[P] = (int) (rand() % 52 + 1);
}
  
void sortArray( int N[], int T )
{
}
  
void printArray( int N[], int T )
{
    printf("LOTTO PICKS\n");
  
    for (int P = 0; P < T; P++)
        printf("%d\n", N[P]);
}
  
void main( void )
{
    srand(time(NULL));
  
    int PICKED[] = {0,0,0,0,0,0};
  
    fillArray(PICKED, SIZE);
    sortArray(PICKED, SIZE);
    printArray(PICKED, SIZE);
}

I have tried this, prints out but will not generate random numbers

#include <stdio.h>
#include <stdlib.h>
#include<time.h>

#define SIZE 6
#define MAX 53

void printArray(int N[], int T);
void fillArray(int N[], int T);

int main(void)
{
srand(time(NULL));

int PICKED[] = {0,0,0,0,0,0};

fillArray(PICKED, SIZE);
printArray(PICKED, SIZE);

return 0;
}

void fillArray(int N[], int T)
{
for(int P=0; P<SIZE; P++)
{
N[P] = rand() % 52+1;

for(int PASS=0; PASS<P; PASS++)
{
if(N[PASS] == N[P])
{
N[P] = (int) (rand()%52 +1);
P=-1;
}
}
}
}


void printArray(int N[], int T)
{
    int PASS, P;

    for(P=0; P<SIZE-1; P++)
    {

        for(PASS = P + 1; PASS < SIZE; PASS++)
        {
	    if(N[P]>N[PASS])
            {
       	        T = N[PASS];
		N[P] = N[PASS];
		N[P] = T;
            }
        }
    }

    printf("\nLOTTO PICKS\n\n");
    for(int P=0; P<SIZE; P++)
       printf("%d ", N[P]);

    printf("\n");

}

I need it to print for example

and cannot seem to fix it to do that

Did you implement sortArray() (or just leave it empty)?

In function fillArray:

kbury wrote:
P=-1;

is wrong, change to

PASS = -1;

In function printArray

kbury wrote:
N[P] = N[PASS];

is wrong, change to:

N[PASS] = N[P];

Some remarks (feel free to ignore...)

There are better ways for implementing the fillArray function (i.e. avoiding the 'duplicates' extraction).
Messing up with the loop index is a very inelegant practice.
printArray really should be called sortArray.

Thank you very much for your help. I have been working on this for about one week now. I really appreciate it.

It works perfect now.
