<vector>

template<class T, class A>
bool operator>=(const vector<T, A>&v1, const vector<T, A>&v2) ;

Returns true if !(v1 < v2).


Sample

#include <vector>
#include <iostream>

int main()
{
	std::vector<int> c1, c2, c3, c4 ;
	int i ;

	for (i = 0; i < 10; i++)
	{
		c1.push_back(i) ;
		c2.push_back(i*i) ;
		c3.push_back(i*i*i) ;
		c4.push_back(i) ;
	}

	if (c1 == c4)
		std::cout << "c1 == c4" << std::endl ;
	
	if (c2 != c3)
		std::cout << "c2 != c3" << std::endl ;

	if(c2 < c3)
		std::cout << "c2 < c3" << std::endl ;

	if(c3 > c2)
		std::cout << "c3 > c2" << std::endl ;

	c4.push_back(29) ;

	if (c1 <= c4)
		std::cout << "after c4.push_back(29), c1 <= c4" << std::endl ;

	if (c3 >= c2)
		std::cout << "c3 >= c2" << std::endl ;
	
	std::swap(c3, c2) ;

	std::cout << "after swapping c3 with c2, " ;
	if (c3 >= c2)
		std::cout << "c3 >= c2" << std::endl ;
	else
		std::cout << "c3 < c2" << std::endl ;

	return 0 ;
}

Program Output

c1 == c4
c2 != c3
c2 < c3
c3 > c2
after c4.push_back(29), c1 <= c4
c3 >= c2
after swapping c3 with c2, c3 < c2
