Question

Updated
This is a basic programming doubt, i just started to learn c and c++
i have two loops i.e.

if (n==null)
{

do loop 1

}
else //(n!=null)
{

do loop2

}

now I have to update the above code, with a single loop i.e. when n==null or n!=null do the loop 1 alone

how can i update.?

can i do like this

while(n==null || n!=null)
{

do loop 1

}

is || operator above does the job what i expected?

Answer 1

Note that

while(n==null || n!=null)
{
    do loop1
}

is an infinite loop because n==null || n!=null is always true.

Probably you mean

if(n==null || n!=null)
{
    do loop1
}

which for the above remark is simply

do loop1

In any case I suggest you to give a look to the Truth Tables.
