指针数组

指针数组

stCam* a[5]

考虑结合的先后顺序，[ ]优先级最高，所以是一个数组，数组里面存放的是结构体stCam的指针

#include <iostream>

struct stCam
{
	int a;
};

struct stCamInfo
{
	/*指针数组，数组里面存放的是stCam结构体的指针*/
	 stCam* a[5];
};

int main()
{
	std::cout << "hello1" << std::endl;
	stCamInfo stcam1;
	for (int i = 0; i < 5; i++)
	{
		stCam* pstcam = (stCam*)malloc(sizeof(stCam));
		pstcam->a = i;
		stcam1.a[i] = pstcam;

	}
	for (int i = 0; i < 5; i++)
	{
		std::cout << stcam1.a[i]->a << std::endl;
		free(stcam1.a[i]);
	}
	std::cout << "hello" << std::endl;
	

	return 0;

}
