将数字转化为液晶显示屏的样子

发一个很蛋疼的程序，将一个数字转化为液晶显示屏显示的样子：第一个输入是尺寸，第二输入是要转化的数字，当两个参数都为0的时候结束输入：

#include<iostream>
using namespace std;

struct Print{
	int size;
	int numPrint;
};

void printNum(Print print);

int main(){
	Print *prints = new Print[10];
	int index = 0;

	int size;
	int numPrint;

	cin>>size;
	cin>>numPrint;

	while(size != 0 && numPrint != 0){
		Print *print = new Print();
		print->size = size;
		print->numPrint = numPrint;

		prints[index] = *print;
		index++;
		cin>>size;
		cin>>numPrint;
	}

	for(int i = 0; i < index; i++){
		printNum(prints[i]);
		cout<<endl<<endl;
	}
	system("pause");
}

void printNum(Print print){
	int size = print.size;
	int numPrint = print.numPrint;

	int *nums = new int[8];
	int index = 0;
	while(numPrint !=  0){
		int temp = numPrint - (numPrint / 10) * 10;
		nums[index] = temp;
		numPrint = numPrint / 10;
		index++;
	}

	for(int row = 0; row < 2*size + 3; row++){
		for(int i = index - 1; i >= 0; i--){
			if(row == 0){
				switch(nums[i]){
