c++ 实例化一个std::向量

[c++]代码库

// 实例化一个std::向量
#include <vector>

int main() {
	std::vector<int> vecDynamicIntegerArray;

	// Instantiate a vector with 10 elements (it can grow larger)
	std::vector<int> vecArrayWithTenElements(10);

	// Instantiate a vector with 10 elements, each initialized to 90
	std::vector<int> vecArrayWithTenInitializedElements(10, 90);

	// Instantiate one vector and initialize it to the contents of another
	std::vector<int> vecArrayCopy(vecArrayWithTenInitializedElements);

	// Instantiate a vector to 5 elements taken from another
	std::vector<int> vecSomeElementsCopied(vecArrayWithTenElements.begin(),
			vecArrayWithTenElements.begin() + 5);

	return 0;
