C Language for beginners

Arrays in C

  
   Collection of single type of elements in a Single variable is Called Array 
Array - [ ] this brackets indicates array 
Array Indes [ ] always start from zero 

Advantages 

1) Memory will be created automatically 
2) We can store values in single variable 

Disadvantages 

1) Array size always static, We can declare initially 
2) Ones we declare array size we can not Increase or Decrease 

Syntax 

   datatype<variable>[size]; 

IF defination


  If condition is true then only excutes statments and shows result other wise out does not display result

Syntax

   IF(conditon)
{
    Statement 1 ;

     Statement 2 ;
             :
             :
             :...etc.;
}

    If condition is true then only excutes statments and shows result other wise out does not display result So we have Use else 

Do While Defination


    In Do-While frist it is enters into the loop excutes all the statements and cheks the conditon if the conditon is true again enters into the loop excutes all statements these phrases repeat untill conditon became false

Syntax

Do  {
    Statement 1 ;

     Statement 2 ;
             :
             :
             :...etc.;
}While(conditon);

Do while is compalsary Excutes all statements one time without depends on the condion

Else If In C Language


   If condition is true then only excutes statments and shows result other wise
Cheks the Else conditon if conditon is true excutes the statements and display result according to else conditon

  Syntax

     If (conditon)
  {
   Statement 1 ;
   }
  Else (conditon)
{
Statement 2 ;
}

C For Loop definition

For Loop

As for loop first checks installation, again checks if the condition is true it enter into the loop executes all the statements after increment update and check again the condition do the same phrases until condition is false


Syntax

  for(intilation;condition;update)
{
    Statement 1 ;

     Statement 2 ;
             :
             :
             :...etc.;
}

Nested loop or Inner loop


     Writting the loop side the loop is called Inner loop

   Syntax :

   While(condition)
  {
     Statement 1 ;
            :
  While(condition)
   {
     Statement 1  ;
            :
    }

Explanation

   It cheks the while conditons if the both loops are true enter the inner loop where the outer loop runs n times and consists of another loop inside it. The inner loop runs m times. Then, the total number of times the inner loop runs during the program execution is n*m.

While defination in c

In while loop it cheks the conditon frist if the conditon is ture it enters the loop excutes the all the statements and after that it cheks condition again,exutes statements utill conditon false. If the condition is false it come out from the loop.

Syntax

While(conditon)
{
Statement 1 ;
Statement 2 ;
Statement 3 ;
         :
}

In while loop we can also use if,else,else-if,...etc
