C語言趣事之內存泄露

C語言定義變量，分配內存時採用的是棧模式，於是乎，就有了如此如此，這般這般的效果

#include<iostream>
using namespace std;

int main()
{
	int a = 66666;
	int b = 22222;
	int c[2] = {333333,44444};
	
	cout << " 修改前的值 " << endl;
	
	cout << " c[2]= " << c[2] << endl;
	
	cout << " c[3]= " << c[3] << endl;
	
	c[3] = 12345; //修改c[3]的值
	
 	cout << "修改後的值：" <<endl;

	cout << " c[3]= "<< c[3] << endl;
	
	cout << "  a= "<< a << endl;
	 
	return 0;
} 

同理，我們可以利用指針這種東西，如下

#include<iostream>
using namespace std;

int main()
{
	int a = 0;
	int *p = &a;
	
	for(int i=0;i<10;i++)
	{
		cout << p << " : ";
		cout << *p++ << endl;
	}
	
	return 0;
}
