//In the above program, the `else` block will be executed because the test condition ` a > 10 ` since the value of
//`a` is `5`, the condition results in a zero value representing the condition failed.

#include <stdio.h>

}

//In the above program, until the `if` after the else, the execution of the program is exactly same as the previous program.
  //The only difference lies when the `else` block is about to be executed, another condition is tested, because we 
  //have now added an `if` to it. So this else will only execute if the `if` statement succeeding it is also true.
