break:
-In C programming language, break is used in terminating the loop immediately after it is encountered.
-The break statement is used with conditional if statement.
-Generally break statement is used in switch case statement at the end of the each and every case.

example:
              break;


continue:
-It is sometimes desirable to skip some statements inside the loop of a program.
-At that time or situation, continue is used.

example:
             continue;

go to statement in c programming language.

- In c programming language, if statement, if...else statement, switch statements provides conditional jumps.
- A goto statement in C programming language provides an unconditional jump from the goto to a labeled statement in the same function.
- Use of goto statement is highly discouraged in c programming language.
- Because it makes difficult to trace the control flow of a program making the program hard to understand and debug.

- Syntax:
goto label;
.
.
.
label: statement;

-Example:

#include<stdio.h>
#include<conio.h>

void main()
{

  int number = 10;

  A:
       do
       {
          if( number == 15)
      {
         number = number + 1;
         goto A;
      }
      printf("\n value of number is: %d",number);
      number++;
   
   }while( number < 20 );

   getch();
}

OUTPUT:

value of number is:11

value of number is:12

value of number is:13

value of number is:14

value of number is:15

value of number is:16

value of number is:17

if...else if ladder(multiple if else)

- In c language, if else statement provides two way decision only.

- In some case, we need to check multiple choice.

- At that time, we can use if...else if ladder(multiple if else statement).

- if...else if ladder provides multi-way decision. There may be more than one condition in Program at that time use if..else if ladder.

syntax:

     if(condition-1)

          statement-1;

     else if(condition-2)

          statement-2;

     else if(condition-3)

          statement-3;

          .

          .

          .

     else if(condition-n)

          statement-n;

     else

          statement;

- In if..else if ladder, the condition-1 is true than it will execute the statement-1.

- If the condition-2 is true than it will execute the statement-2. Same way it will check

All the condition.

Flow Chart:

multiple if else

Example: A c program to check the given year is leap year or not.

#include<stdio.h>

#include<conio.h>

void main()

{

  int year;

  printf("Enter a year:");

  scanf("%d", &year);

  if(year%4 == 0)

      printf("\n This is a leap year.", year);

  else if (year%400 == 0)

      printf("\n This is a leap year.", year);

  else if(year%100 == 0)

      printf("\n This is not a leap year.", year);

  else

      printf("\n This is not a leap year.", year); 

  getch();

}

OUTPUT:

Enter a year: 2011

This is not a leap year.
