Conditionals, nest question ?

Question

Hey guys. Got another question ?
What is C++ referring to when it goes on about NESTING if statements ?
Does it just mean that C++ enables you to put as many if statements in the code as you would like ?
Going through the if and else conditionals right now and all these curly brackets are confusing the hell out of me.
Thanks for your help

Answer 1

Not into C++ but AFAIK nesting is putting one block inside another (blocks are often wrapped in curly braces {} as in C++). In this case it would mean if block inside if block:

if (this) {
if (this too) {
if (thisCouldBeImportant) {
// do something
}
}
}

Answer 2

So, because there is 3 opening curly brackets on the If statements then there has to be 3 closing brackets on the bottom ??

What about this way.
if(this){
if(this too){
if(this as well){
}

Some people are putting just one curly bracket instead of 3 ?
