12 Jan Two Dimensional Arrays in C++
In the previous lesson, we saw how to work with Arrays in C++. An array can have two or more dimensions. Here we will discuss about two-dimensional arrays. A two dimensional array as the name suggests has two dimensions, not what we saw in one-dimensional arrays.
Before the example, let us see the syntax,
|
1 2 3 |
datatype name_of_array[rows_count][columns_count]; |
Considering the above syntax, let us see an example, with 3 rows and 3 columns in a two-dimensional array,
|
1 2 3 |
int cricket[3][3]; |
Let us now see how rows and columns work in a two-dimensional array,
Now, let us see a complete example to learn more about two-dimensional arrays.
Example
Let us see a program where we will print the rank and points of 5 cricketers. Here, you can see an array with rows and columns i.e. two-dimensional.
We’re displaying the rank and points for 5 teams, but before that you need to input the values. The cin in C++ is used to input values and cout to get the output,
|
1 2 3 4 |
cin: Standard input stream in C++ cout: Standard output stream in C++ |
Here, cric[0][1] would mean 1st row and 1st column, cric[0][2] is 1st row and 2nd column, etc
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 |
#include <iostream.h> #include <conio.h> void main () { int cric[4][2]; int i, j; for (i=0;i<5;i++) { cout<<"\n Enter rank and points for 5 teams:"; cin>>cric[i][0]; cin>>cric[i][1]; } // displaying output for(i=0;i<5;i++) cout<<"\n"<<cric[i][0]<<"\t"<<cric[i][1]; getch(); } |
The following is the output,
Here, you saw the following two dimensional arrays,
In this lesson we learned how to work with Multi-Dimensional array in C++.
