if ur willing to help me understand one and multi-dimensional arrays plz reply to my email. styles8687@yahoo.com

It doesn't work that way; this isn't 1-1. A one dimensional array is a list of items. int i[10]; declares an array of 10 ints which are accessed as i[0] through i[9]. An example of a 1D array is a set of coordinates, for example int i[3] can store x,y and z components of a point in 3D space. A two dimensional array is a list of arrays. int i[10][10]; declares an array of 10 arrays of 10 ints which are accessed as i[0][0] through i[0][9], i[1][0] through i[1][9] and so on. If you're writing a program to play chess you might use a 2D array. An n-dimensional array simply extends the above to as many dimensions as you want, for example a five dimensional array would be int i[10][10][10][10][10];. Clear?

well man you have many tutorials on array theme as xpiotos has already said... array is just bunch of elements of some type put on one place... and as I saw xpiotos has also mentioned that calculation is starting from zero so it means array of 10 elements is going 0,1,2,3,4,5,6,7,8,9 if there would be 10 it would be 11 element array because every array contains N-1 numbers in itself... int x[5] allocates 5 elements of type integer someclassorstructname x[10] defines 10 elements of your own type same with pointers int *x = new int[5]; this is dinamicaly allocated array of five elements

Not quite. N-1 is the maximum index, but if you define int x[N] then it will contain N numbers. int x[3] defines three elements, x[0], x[1] and x[2].

What is a Multidimensional Array? A Multidimensional array is an array of arrays. How are Multidimensional Arrays represented in C++ int Exforsys[3][4]; int Exforsys[3][4][2]; it is possible to handle multidimensional arrays of any number of rows and columns in C++ programming language. This is all occupied in memory. Better utilization of memory must also be made. Multidimensional Array Example: Code: #include <iostream.h> const int ROW=4; const int COLUMN =3; void main() { int i,j; int Exforsys[ROW][COLUMN]; for(i=0;i<ROWS;i++) for(j=0;j<COLUMN;J++) { cout << "Enter value of Row "<<i+1; cout<<",Column "<<j+1<<":"; cin>>Exforsys[i][j]; } cout<<"\n\n\n"; cout<< " COLUMN\n"; cout<< " 1 2 3"; for(i=0;i<ROW;i++) { cout<<"\nROW "<<i+1; for(j=0;j<COLUMN;J++) cout<<Exforsys[i][j]; } The output of the above program is Enter value of Row 1, Column 1:10 Enter value of Row 1, Column 2:20 Enter value of Row 1, Column 3:30 Enter value of Row 2, Column 1:40 Enter value of Row 2, Column 2:50 Enter value of Row 2, Column 3:60 Enter value of Row 3, Column 1:70 Enter value of Row 3, Column 2:80 Enter value of Row 3, Column 3:90 Enter value of Row 4, Column 1:100 Enter value of Row 4, Column 2:110 Enter value of Row 4, Column 3:120 COLUMN 1 2 3 ROW 1 10 20 30 ROW 2 40 50 60 ROW 3 70 80 90 ROW 4 100 110 120 ...............................................................

Code: #include<iostream.h> #include<conio.h> #define ROW 4; #define COLUMN 3; void main() { clrscr(); int i,j,k; int Exforsys[ROW][COLUMN]; cout<<".::Enter New Array::..\n"; for (i=0;i<ROW;i++) for(j=0;j<COLUMN;j++) { gotoxy(5+(i*4),5+(j*2)); cin>>Exforsys[i][j]; } k=j+2; cout<<"\n---------\n"; for (i=0;i<ROW;i++) for(j=0;j<COLUMN;j++) { gotoxy(5+(i*4),k+(j*2)); cout<<Exforsys[i][j]; } } 1 10 20 30 2 40 50 60 3 70 80 90 4 100 110 120 ----------- 1 10 20 30 2 40 50 60 3 70 80 90 4 100 110 120
