else


An if statement can be followed by an optional else statement, which executes when the boolean expression is false.

Syntax:
if(boolean_expression)
{
   // statement(s) will execute if the boolean expression is true
}
else
{
  // statement(s) will execute if the boolean expression is false
}


Example:

#include 
using namespace std;
 
int main ()
{
   // local variable declaration:
   int a = 100;
 
   // check the boolean condition
   if( a < 20 )
   {
       // if condition is true then print the following
       cout << "a is less than 20;" << endl;
   }
   else
   {
       // if condition is false then print the following
       cout << "a is not less than 20;" << endl;
   }
   cout << "value of a is : " << a << endl;
 
   return 0;
}
