Thread: Insert new element into a vector

I am trying to insert a new element into a vector in C++ under Ubuntu Linux.

The following is what I did, where v contain some element already. InsertElementNo is the element number the new content "entry" should be inserted.

For example:

v contains "Test,Is,Good"
If entry = "Lord" and InsertElementNo = 2,
After v.insert v should look like "Test,Lord,Is,Good"

Code:

    vector <string> v;
    vector <string>::iterator pos = v.begin();
    .......
    v.insert(pos+(InsertElementNo-1), entry);

However the above code gives me "segmentation error".

Couldn't figure out why.
