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.
