將二維陣列切割為多個3*2的二維陣列

• 需求如圖：

• 希望輸出： 每6個數字存入新陣列的一行
  1,2，5,6，9,10
  3,4，7,8，11,12
  13,14,17,18,21,22
  15,16,19，20,23,24

#include<iostream>
using namespace std;
int main() {
	int a = 0, b = 0, t = 0, m = 0;
	int change[4][6];
	int L[6][4] = { {1, 2, 3, 4},
					{5, 6, 7, 8},
					{9, 10, 11, 12},
					{
 
13, 14, 15, 16},
					{17, 18, 19, 20},
					{21, 22, 23, 24} };
	while(a < 6){
		for (int i = a; i <= a + 2; i++) {
			for (int j = b; j <= b + 1; j++) {
				change[m][t] = L[i][j];
				t = t + 1;
			}
		}
		t = 0;
		m = m + 1;
		b = b + 2;
		if (b == 4)
		{
			b = 0;
			a = a + 3;
		}		
	}
	
	for
 
 (int i = 0; i < 4; i++) {
		for (int j = 0; j < 6; j++) {
			cout << change[i][j] << " ";
		}
		cout << endl;
	}
	system("pause");
	return 0;
}
