C Program to Insert Node at The End of Single Linked List

Single Linked List: - Simply a list is a sequence of data, and the linked list is a sequence of data linked with each other. 

The formal definition of a single linked list is as follows.

The single linked list is a sequence of elements in which every element has link to its next element in the sequence.

In any single linked list, the individual element is called as "Node". Every "Node" contains two fields, data and next. The data field is used to store the actual value of that node and the next field is used to store the address of the next node in the sequence.

C Program For Printing Matrix & Sum of the Values in Each Rows Using The Concept of 2D / Two dimensional array and FOR Loop | C Program for Printing Values in Matrix Form & Sum of the Values in Each Rows By Using Two Dimensional Array and FOR Loop

C Program For Printing Matrix & Sum of the Values in Each Rows Using The Concept of 2D / Two-dimensional array and FOR Loop 

C Program for Printing Values in Matrix Form & Sum of the Values in Each Rows By Using Two Dimensional Array and FOR Loop 

2D / Two-dimensional array :- A 2D array has a type such as int[][] or String[][], withtwo pairs of square brackets. The elements of a 2D array are arranged in rows and columns, and the new operator for 2D arrays specifies both the number of rows and the number of columns.

An array of arrays is known as a 2D array. The two dimensional (2D) array in C programming is also known as matrix. A matrix can be represented as a table of rows and columns. Before we discuss more about two Dimensional array lets have a look at the following C program

 The simplest form of multidimensional array is the two-dimensional array. A two-dimensional array is, in essence, a list of one-dimensional arrays. To declare a two-dimensional integer array of size [x][y], you would write something as follows − Type arrayName [x][y]

Where type can be any valid C data type and arrayName will be a valid C identifier. A two-dimensional array can be considered as a table which will have x number of rows and y number of columns. A two-dimensional array a, which contains three rows and four columns can be shown as follows −

Thus, every element in the array a is identified by an element name of the form a[ i ][ j ], where 'a' is the name of the array, and 'i' and 'j' are the subscripts that uniquely identify each element in 'a'.
