Computer Programming: Operators in c# console application


It is a symbol, which is performed operation on operands, operation can be mathematical or logical. In c#, operators are categories in three basic parts first one is unary operator and second one is binary operator and last one is ternary operator. In unary operator we use single operand like.
++a // here a is a "operand"
In Binary operator we use two operand. Like
In ternary operator we use three operand like

Assignment Operator (=)

if we create a variable of type integer also we want to initialize it with some value then we should use assignment operator like.

int a=10;

Here, variable a is initialized with value 10. It means you can say the right hand side value is copy to left hand side variable using assignment operator.

Arithmetic Operators ( +,-,*,/,%)

Basically arithmetic operators are used for doing mathematical calculation like addition of two or more numbers , multiplication, division, subtraction, and remainder. lets take a simple example to understand arithmetic operators. If the total collection by five students is five thousand then find the average value?.
int collected_money=5000;
int total_student =5;
int avg=collected_money/total_student;

Ternary operator (?, : )

In ternary operator we have three operands, in which first operand is used for check the condition and other two operands is used for giving results. Let’s take a simple example to understand the ternary operator.

Int firstnumber=10;
Bool result;
Result = firstnumber>10? True: false;

In the preceding example, if condition becomes true or you can say if firstnumber is greater than to 10 then ternary operator gives  ‘true’ in results otherwise gives ‘false’.

Comparison Operators (< , > ,<=,>=,!=,==)

using comparison operator you can perform Boolean operation between operands known as comparison operator. Lets take an simple to understand comparison operator
 class Program
        static void Main(string[] args)
            int a = 10;
            if (a==10)
                Console.WriteLine(string.Format("The value of variable ={0}", a));
            Console .ReadKey (false);
Computer Programming : Operators in c# console application Here, condition if check equality operation between operands, a and constant value 10. If condition becomes true, output comes "The value of variable=10".



  Logical operator (&&,|| )

Perform logical operation between Boolean operands known as logical operator. Lets take a simple example
  class Program
        static void Main(string[] args)
            bool a = true;
            bool b = true;
            if (a&&b)
                Console.WriteLine("condition becomes true");
            Console .ReadKey (false);

difference between structure and union in C Language

In c language article we will see the difference between union and structure. Both are the user define datatype in c language. See the table which is mentioned below: ASP.NET Video Tutorial Series Structure Union1.The keywordstruct is used to define a structure 1. The keyword union is used to define a union. 2. When a variable is associated with a structure, the compiler allocates the memory for each member. The size of structure is greater than or equal to the sum ofsizes of its members. The smaller members may end with unused slack bytes. 2. When a variable is associated with a union, thecompiler allocates thememory by considering the size of the largest memory. So, size of union is equal to the size of largest member. 3. Each member within a structure is assigned unique storage area of location. 3. Memory allocated is shared by individual members of union. 4. The address of each member will be in ascending order This indicates that memory for each member will start at different offset v…

Difference between Linear search and Binary Search in c language

SQL Video Channel : Download all SQL Video

Binary Search Linear Search Works only on sorted items. such as  1,2,3,4,5,6  etc
Works on sorted as well as unsorted items. 12,4,5,3,2,1 etc Very efficient if the items are sorted Very efficient if the items are less and present in the beginning of the list. such as Suppose your list items are : 12,3,4,5,1 and you want to search 12 number then you get beginning in the list. Works well with arrays and not on linked lists. Works with arrays and linked lists.
Number of comparisons are less More number of comparisons are required if the items are present in the later part of the array or its elements are more.

Memory representation of Linked List Data Structures in C Language

Memory representation of Linked List

             In memory the linked list is stored in scattered cells (locations).The memory for each node is allocated dynamically means as and when required. So the Linked List can increase as per the user wish and the size is not fixed, it can vary.

               Suppose first node of linked list is allocated with an address 1008. Its graphical representation looks like the figure shown below:

      Suppose next node is allocated at an address 506, so the list becomes,

  Suppose next node is allocated with an address with an address 10,s the list become,

The other way to represent the linked list is as shown below:

 In the above representation the data stored in the linked list is “INDIA”, the information part of each node contains one character. The external pointer root points to first node’s address 1005. The link part of the node containing information I contains 1007, the address of next node. The last node …
