4. If-else if ladder - The statements inside the body of “if” only execute if the given condition returns true, if not then the "else if"condition is checked , then if the true is returned then "else if" condition is executed and if the condition returns false then the statements inside “else” is executed.

Syntax :

if (condition)

{ 

       // Body of the loop.

       // Body of the loop.

       // These statements will only execute if all the above conditions are false.

}

Example of If-else if ladder in C++

#include<iostream.h>

#include<conio.h>

int main()

{

   int  a=15,b=10;

   if(a<b)  //if condition statement

    {

       cout<<"Value of a is less than b";  //display output

    }

   else if(a>b)  //else if condition statement

    {

       cout<<"Value of b is less than a."; //display output

    }

   else  //else condition statement

    {

       cout<<"Value of a is equal to b."; //display output

    }

  getch();

}

OUTPUT:

Value of b is less than a.
