利用下标变量显示数组a&利用指针变量显示数组a

#include <iostream>

using namespace std;

int main()
{
//声明数组、变量和指针变量
int a[2][3], i, j;
int *ip;

//从键盘上为数组a赋值
for ( i = 0; i < 2; i++)
{
	for ( j = 0; j < 3; j++)
	{
		cout << "a[" << i << "]j[" << j << "]=";
		cin>> a[i][j];
 
	}
}
 
//利用下标变量显示数组a
for ( i = 0; i < 2; i++)
{
	for ( j = 0; j < 3; j++)
	{
		cout << "a[" << i << "]j[" << j << "]=" << a[i][j]<<"    ";
 
	}cout << endl;
 
}
