What is the point of nesting if statements?

Answer 1

@Muhthukamar in cases such as that it is easier to write switch statements, as "Case _" is very easy to read and write since you give them a title without commenting which is what you would need to do in nested if statememts

Answer 2

A nested if statement is different then an else statement

a nested if would be a check if something else is true
example

int x = 25;
if (x > 20)
{
if (x == 25)
{
//do something special because it's 25
}
}

end example

A else is used to caught if a statement is false and do something

example

int x = 10

if (x > 20)
{

}
else
{
//do something because it's not greater then 20
}

end example

else would only be executed if the if is false

you can also use

else if to add other checks before just plain else and once one is true it executes that and ignores the rest even if others are true

example

int x = 15;

if (x > 20)
{
//would be false and any code here is ignored
}
else if (x < 20)
{
//this would be true so this would execute
}
else if (x > 10)
{
//this would do nothing cause a previous statement was true already and the rest is ignored even if true
}

end example

hope this helps
