C++两数之和

给出一组数组，给出一个target值，要求输出i,j使Arry[i]+Arry[j]=target
例如：
Arry[5]=[1,2,3,4,5]
target=6
output[0,4]、[1,3]

代码如下

# include <iostream>
using namespace std;
class solution
{
public:
	int arry[10];
	int target;
	void Set()
	{
		int i;
		cout<<"Enter 10 numbers for a arry:"<<endl;
		for(i=0;i<10;i++)
		{
			cin>>arry[i];
		}
	}
	void Show()
	{
		int i;
		cout<<"Arry is:"<<endl;
		for(i=0;i<10;i++)
		{
			cout<<arry[i]<<" ";
		}
	}
	void Find()
	{
		int target;
		int i,j;
		cout<<endl;
		cout<<"target=";
		cin>>target;
		for(i=0;i<10;i++)
		{
			for(j=i+1;j<10;j++)
			{
					if(arry[i]+arry[j]==target)
					{
						cout<<"["<<i<<","<<j<<"]"<<endl;
					}
			}
		}
	}
};
int main(void)
{
	solution A;
	A.Set();
	A.Show();
	A.Find();
	system("pause");
	return 0;
}
