Say i have something like this
if(mark >= 50)
if(mark >= 80)
//do stuff
else
//do stuff
else
//do stuff
how would those if''s and else''s be used.
Would it match the first if with the last else and the second if with the first else?(in java)
Seriously, how long would it take for you to write a quick test to figure it out? And more importantly, why are you writing code like this? You can use braces with if/else statements for a reason.
if(mark >= 50)
if(mark >= 80)
//do stuff
else
//do stuff
else
//do stuff
I think you constructed the code incorrectly. The correct code should be look like this.
if(mark >= 50)
{
do stuff
}
else if (mark >= 80)
{
do stuff
}
else
{
do stuff
}

Both sets of code do the same thing, and each are perfectly valid ways of doing it. It just comes down to a personal preference.

True, BUT, that assumes that "do stuff" is only one statement( a '';'', not a line essentially.) Brackets would be good, but they''re not necessary.
''else if'' and ''else'' statements are paired with the nearest previous ''if'' statement. Only one ''else'' per ''if'' is allowed. As a matter of style, I personally only use unbracketed ''if'' statements in the innermost level of nested ''if''s.

if(mark >= 50)if(mark >= 80)//do stuffelse//do stuffelse//do stuff is equivalent to...
if (mark >= 50){ if (mark >= 80) { // do stuff } else { // do stuff }}else{ // do stuff} You should always use brackets if you have nested ifs. You *have* to use brackets if you want "// do stuff" to be multi-lined.

Well it's quite clear even witout bracets if you use proper indenation.
But personally I would use just brackets around the outer if, because the inner one consits of just one line statements, like this. For symmetry I would put a bracket around the last else too.

But the compiler doesn't look at indentation, so the following code will not do what te indentation sugests:
if(mark >= 50) if(mark >= 80) //do stuffelse //do stuffAlso, there is no need to use nested if statements in this code, the following will do:
if (mark >= 80) { // do stuff a} else if (mark >= 50) { // do stuff b} else { // do stuff c}(Actually the second if is nested inside the else, but you don't have to worry about that)
