Write a program using two dimensional array

TheseArrays can be initialized by putting the curly braces around each row separating by a comma also each element of a matrix should be separated by a comma. In a main function first of all the two dimensional integer array will be declared by the name of a matrix , then the integer elements will be stored in an array with the help of a nested For loop.

Then again with the help of another nested loop the program will print the elements stored in the matrix on a computer screen. The 2-D arrays which are declared by the keyword char and able to store characters are called two dimensional character arrays. As you can see the above array is declared by a keyword int therefore it is a 2-D character array.

Now consider a following example of a complete program which will elaborate the working of character array. As you can see the above array is declared by a keyword int therefore it is a two dimensional character array. In a main function 2-D character arrays will be declared by the name of a cmatrix. Those two parameters are usually length and breadth since it is a physical quantity. Similarly, a two-dimensional array is an array which technically has one row of elements, however, each row has a bunch of elements defined by itself.

Basically, you need to define both the rows and columns and then go ahead with declaring the elements in the respective locations or indexes. As you can see in the example given above, firstly, you need to specify the number of rows that you are assigning with the array. Hence, the elements are arranged accordingly and you will get your two-dimensional array. The outer for loop to loop through all the rows and inner for loop to loop through all the columns.

The following program will clear everything. There is nothing new in this previous program that deserves any explanation. We are just using two nested for loops. The first nested for loop takes input from the user. And the second for loop prints the elements of a 2-D array like a matrix.

In such cases, the remaining elements will be given the value of 0. In 2-D arrays, it is optional to specify the first dimension but the second dimension must always be present. This works only when you are declaring and initializing the array at the same time.
