When and why should I use a nested if statement instead of an else if statement?

Question

I've been having trouble figuring out when I should use a nest if statement instead of an else if statement

Answer 1

Taste 2nd condition will be checked only if 1st condition is true , in case of && also.😅
//though there are some cases where we need to multiple nested if() . Example : like there are 3 if () & in 2nd if () we need to excute some more statements before the reaching to final inner most loop .

that is why I typed "if U specifically want some statement(s) to excute if() certain conditions meet" //those all statement(s) are together in same inner most loop .☺

Answer 2

U don't need to do nesting if() statement , just simply used AND (&&) between condition if U specifically want some statement(s) to execute if certain conditions meet .☺👍

1)nesting if() , when more than 1 condition to be true for some statement(s) to execute .
2)nesed if else , when U want either of other statement(s) to execute if if () condition evaluates to false . //else execute 1st statement(s) only.

Answer 3

Yes but for some case nested if are needed for simpler code, or need to peform something before the second check

I agree with using && but i disagree "dont need"

Answer 4

Nested if usually used when you need 2 condition to fullfil
if(A)
if(B)
//A and B needs to be true
if(C)
// A and C needs to be true

if(A)
//if this true, B wont be executed
else if(B)
//Only one can be executed
