I'm using a vector array by using this code segment.

C++

cliext::vector<long> Characterimgs;

Please can someone tell me how can I remove a particular element from this array. I have used erase() but it didn't work as I wish. I want to remove only one element.Thanks.

This would be so much easier if you posted your code. You say erase() doesn't work but that is the way to do it.

Characterimgs.erase(Characterimgs.begin()+c);

c is the element I want to remove.

That's it. At least if c is an index into the array. If you want to remove an item whose value is (long)c then first you have to find it with this: http://msdn.microsoft.com/en-us/library/bb385676.aspx and this returns an iterator for you that you can pass to erase.

Can you be more specific, so we can try to help?

Post the problematic code, for start.

Solution 1

erase should actually work. See std::vector::erase[^] for usage sample.
