Browse - programming tips - convert vector index to an iterator

Q.  How do I convert an integer index into a STL vector into
and iterator?  I need an iterator for insert().

A.  Do this:

#include <vector>

typedef std::vector<char *> MYARRAY;

void insert_with_index(MYARRAY &a, const int index, char *s)
{
	MYARRAY::iterator	it;

	it = &a[index]; // Convert the index to an iterator

	it = a.begin() + index; // Another way

	a.insert(it, s);
}
