In the beginning had been explained the introduction.<\/h2>\n

A two-dimensional array is the most basic type of a multi-dimensional array in C++. It can be thought of as an array made up of multiple arrays. The following illustration illustrates a two-dimensional array.<\/p>\n

\"2D<\/div>\n

A matrix, which is also known as a two-dimensional array, can be of different types such as integer, character, float, etc., depending on the initialization. In the upcoming section, we will explore the methods of initializing 2D arrays.<\/p>\n

Creating a 2-dimensional array in C++<\/a><\/h2>\n

So, how do we begin a two-dimensional array in C++? It’s as easy as this:<\/p>\n

int<\/span> arr[<\/span>4<\/span>]<\/span>[<\/span>2<\/span>]<\/span> =<\/span> {<\/span>\r\n{<\/span>1234<\/span>,<\/span> 56<\/span>}<\/span>,<\/span>\r\n{<\/span>1212<\/span>,<\/span> 33<\/span>}<\/span>,<\/span>\r\n{<\/span>1434<\/span>,<\/span> 80<\/span>}<\/span>,<\/span>\r\n{<\/span>1312<\/span>,<\/span> 78<\/span>}<\/span>\r\n}<\/span> ;<\/span>\r\n<\/code><\/pre>\n
So, to explain further, we create a two-dimensional array called “arr” that has four rows and two columns. Each element within the array is also an array, but this time it contains integers.<\/p>\n
Another way to initialize a 2D array is by using the following method.<\/p>\n
int<\/span> arr[<\/span>4<\/span>]<\/span>[<\/span>2<\/span>]<\/span> =<\/span> {<\/span>1234<\/span>,<\/span> 56<\/span>,<\/span> 1212<\/span>,<\/span> 33<\/span>,<\/span> 1434<\/span>,<\/span> 80<\/span>,<\/span> 1312<\/span>,<\/span> 78<\/span>}<\/span>;<\/span>\r\n<\/code><\/pre>\n
Also in this situation, arr is a 2D array containing 4 rows and 2 columns.<\/p>\n
Printing a 2D Array in C++ can be rewritten as “Displaying a two-dimensional array in C++.”<\/h2>\n
We have finished the initialization of a 2D array, but without printing it, we cannot verify if it was done correctly.<\/p>\n
Moreover, in numerous instances, it may be necessary to generate a printed 2D array following the execution of certain actions. How can we accomplish this?<\/p>\n
Here’s one way we can accomplish that, as demonstrated in the code provided.<\/p>\n
#<\/span>include<\/span><iostream><\/span><\/span>\r\nusing<\/span> namespace<\/span> std;<\/span> \r\nmain<\/span>(<\/span> )<\/span> \r\n{<\/span>  \r\n\tint<\/span> arr[<\/span>4<\/span>]<\/span>[<\/span>2<\/span>]<\/span> =<\/span> {<\/span>\r\n\t\t{<\/span> 10<\/span>,<\/span> 11<\/span> }<\/span>,<\/span>\r\n\t\t{<\/span> 20<\/span>,<\/span> 21<\/span> }<\/span>,<\/span>\r\n\t\t{<\/span> 30<\/span>,<\/span> 31<\/span> }<\/span>,<\/span>\r\n\t\t{<\/span> 40<\/span>,<\/span> 41<\/span> }<\/span>\r\n\t\t}<\/span> ;<\/span>\r\n\t\t\r\n\tint<\/span> i,<\/span>j;<\/span>\r\n\t\r\n\tcout<<<\/span>\"Printing a 2D Array:\\n\"<\/span>;<\/span>\r\n\tfor<\/span>(<\/span>i=<\/span>0<\/span>;<\/span>i<<\/span>4<\/span>;<\/span>i++<\/span>)<\/span>\r\n\t{<\/span>\r\n\t\tfor<\/span>(<\/span>j=<\/span>0<\/span>;<\/span>j<<\/span>2<\/span>;<\/span>j++<\/span>)<\/span>\r\n\t\t{<\/span>\r\n\t\t\tcout<<<\/span>\"\\t\"<\/span><<<\/span>arr[<\/span>i]<\/span>[<\/span>j]<\/span>;<\/span>\r\n\t\t}<\/span>\r\n\t\tcout<<<\/span>endl;<\/span>\r\n\t}<\/span>\r\n}<\/span>\r\n<\/code><\/pre>\n
