经典游戏的C++实现--2048

摘要: 最近无事，抽空写了2048，代码为c++





main.cpp

#include "function.h"

using namespace std;

int main(int argc, char *argv[])
{
SetWindows();
if ( !WelCome() ) {exit(0);};//Show the welcome information
system("cls");
int value[5][5]={0};//store each value of the table

//Draw the table
FrameWork(pianx,piany);
//Random create a value
srand(time(0));
value[rand()%4+1][rand()%4+1]=(rand()%2+1)*2;
DrawTable(value,pianx,piany);

//The body of the program
bool keypress=0;
char whichkey;
int score=0;

loop:

//case the input
if (keyleft) {whichkey='l';keypress=1;}
else if (keyright) {whichkey='r';keypress=1;}
else if (keyup) {whichkey='u';keypress=1;}
else if (keydown) {whichkey='d';keypress=1;}
else {keypress=0;}
//end case

if (keypress)
{
//change the value
Change(value,whichkey,score);
//refresh the number display
ClearTable(pianx,piany);
DrawTable(value,pianx,piany);
//show score
Position(pianx+2,piany-2);
setcolor(31);
cout<<"Your Score:"<<score;
}
system("pause>nul");

goto loop;
