Answer 2

Its really just the shorthand way of writing nested if statements.
e.g. [using pseudocode]
IF condition
THEN...
ELSE
IF condition
THEN...
ELSE
THEN...
ENDIF
ENDIF

Answer 3

If your problem has only 2 choices, use if-else.

Answer 4

if (condition)
{
body of your code;
}
if statement is use to check condition if condition is true then body of your code will be execute.

Answer 5

if else
if (condition)
{
body of your code;
}
else
{
body of your code;
}
In this case if statement is use to check the condition, if condition is true then body of if statement will be executed otherwise else part will be executed.

This is the difference between if and ifelse.
