This is how you use it,
the example is done to get you started with out trouble
* the numbers in yellow show the steps in which the coordinates are entered to the program
recommended way of entering coordinates is "4 5" (without "") if you want to enter the coordinate (4,5)
* numbers in red gives the limits of the default console dialog
* numbers in white are the ones you need to enter *according to the steps* inorder to draw the picture shown in the image

Sry guys couldnt post much in the thread coz i was really busy this work with my works and also undergoing some treatments for an injury !!!! Will be back soon with new algorithms !!!!!! But u guys keep posting !!!!!!!!

 

[rclakmal]

Hey Guys a small Programme test ur calculation speed !!! Download it ,extract and simply run the exe file .....Ill post the source code after u test it !!!

When u run the .exe file u will get a message called "This executable was created using ....."

simply press OK and continue .....the reason is i have used a un registered SW to convert my .jar file in to an exe file ......

And there are some erros ....check whether u can find them and Check ur brain and most important thing

POST UR RESULT HERE !!!!!! here is the link

DOWNLOAD IT HERE!!!

Matrix Multiplier

Test Case, you can change these accordingly

C = |12| * |256| 
    |34|   |563|

A = |12| 
    |34|

B = |256| 
    |563|
r = A's row count
c = A's and B's column count
d = B's column count

C will contain the resulting matrix.

#include <stdio.h>
#include <conio.h>

int main()
{
    int r,c,d,x,y,i;
    r=2;
    c=2;
    d=3;
    float A[r][c], B[c][d], C[r][d],D;
    A[0][0]=1;
    A[0][1]=2;
    A[1][0]=3;
    A[1][1]=4;

    B[0][0]=2;
    B[0][1]=5;
    B[0][2]=6;
    B[1][0]=5;
    B[1][1]=6;
    B[1][2]=3;

    for (y=0;y<r;y++){
        for (x=0;x<d;x++){
            D=0;
            for (i=0;i<c;i++){
                    D=D+A[y][i]*B[i][x];
                }
            C[y][x]=D;
            printf("%f ",C[y][x]);
            }
        printf("\n");
        }
    getch();
    return 0;
}

හොද ප්‍රශ්නයක් !
මේකට විසදුමක් විදියට Items Reference File එකට අලුත් entry එකක් දාන්න හැදුවානම් හරි

ITEM_CODE     ITEM_NAME        PRICE_OF_ONE_UNIT     UNIT_TYPE
