A cell reference in Excel refers to other cells to a cell to use its values or properties. So in simple terms, if we have data in some random cell A2 and we want to use that value of cell A2 in cell A1, we can use =A2 in cell A1. So it will copy the value of A2 in A1. So it is called cell referencing in Excel.

For example, suppose you insert C1O.…[Read more]

union is a special data type available in C that allows to store different data types in the same memory location. You can define a union with many members, but only one member can contain a value at any given time. Unions provide an efficient way of using the same memory location for multiple-purpose.

Defining a Union
To define a union, you must…[Read more]

Variables in C
Variable is used to store the value. As name indicates its value can be changed or also it can be reused many times. We have to define its Data Types as shown below.
Syntax

e.g.

int a;
Where ‘a’ is the variables.

Properties of Arrays in C
It is very important to understand the properties of the C array so that we can avoid bugs while using it. The following are the main properties of an array in C:

1. Fixed Size
The array in C is a fixed-size collection of elements. The size of the array must be known at the compile time and it cannot be changed once it…[Read more]

There are two types of arrays based on the number of dimensions it has. They are as follows:

One Dimensional Arrays (1D Array)
Multidimensional Arrays
1. One Dimensional Array in C
The One-dimensional arrays, also known as 1-D arrays in C are those arrays that have only one dimension.

Syntax of 1D Array in C

Initialization in C is the process to assign some initial value to the variable. When the array is declared or allocated memory, the elements of the array contain some garbage value. So, we need to initialize the array to some meaningful value. There are multiple ways in which we can initialize an array in C.

1. Array Initialization with…[Read more]

C Arrays
Array in C is one of the most used data structures in C programming. It is a simple and fast way of storing multiple values under a single name.
