How if statement works?
The if statement evaluates the test expression inside the parenthesis.

If the test expression is evaluated to true (nonzero), statement(s) inside the body of if is executed.
If the test expression is evaluated to false (0), statement(s) inside the body of if is skipped from execution.
C if...else statement

How if...else statement works?
If test expression is evaluated to true,

statement(s) inside the body of if statement is executed
statement(s) inside the body of else statement is skipped from execution.
If test expression is evaluated to false,

statement(s) inside the body of else statement is executed
statement(s) inside the body of if statement is skipped.
if...else Ladder (if...else if....else Statement)
The if...else statement executes two different codes depending upon whether the test expression is true or false. Sometimes, a choice has to be made from more than 2 possibilities.
