for(int i = num-1; i>=0; i--)
{
cout << "reverse: " << array[i] << ", " << endl;
}

I was wondering how do I print an array on a single line? That is, the above code gives me the numbers in a list fashion like this:

reverse: 3,
reverse: 2,
reverse: 4,

where as I just want it as:

reverse: 3,2,4

Thanks a lot in advance!!

have you tried

cout << "reverse: ";
for(int i = num-1; i>=0; i--)
{
cout << array[i] << ", ";
}
cout << endl;

Oh that works for the reverse but I wanted the numbers aligned horizontally not vertically.

Now it gives me:

reverse:
3,
2,
4,

instead of what I want:

reverse: 3,2,4

Thanks a lot again.

Also I noticed when I do:

 
cout << "reverse : , " ; 
for(int i = num-1; i>=0; i--)
{
cout << array[i];
}

It prints out like:

reverse: ,321

But I want it like:

reverse: 3,2,1 with commas in between each number.

So

cout << "reverse : " ; 
for(int i = num-1; i>=1; i--)
{
cout << array[i] << ",";
}
cout << array[0] << endl; //without the ,

You should be able to figure things like this out.

If you print a comma behind the value every iteration of the loop except last one, it would work.

Thanks for helping me out. When I run that code, it comes out like:

reverse: 3,2,4,4

repeating the last number without a comma. How do I not make it repeat the last number? ><'' And why does it repeat the last number in the first place? Thanks a bunch again!!

guy! can't you fix that?

This makes it print... what?

cout << array[0] << endl;

So... what do you want it to NOT print?

How would you do that? //make it print ONE LESS thing that has a comma after it.

It's easy enough to figure out. If nothing else, use trial and error.

Sorry! I'm not comfortable yet with the Syntax (first time learning and getting through this) but I did figure it out! Thanks!! I used an if statement for the , .
