Stuck on a for loop entry
Mar 7, 2013 at 2:11am UTC
I am trying to get this code eventually to read in a maze file to move the smiley face around in. But right now my current snag is the yes or no to enter the for loop.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102
#include <iostream>

#include <time.h>
using namespace std;
int main()
{
int name;
char ans;
cout<<"Please enter Player name:" ;
cin>>name;
cout<<"Are you ready to play?(y/n):" ;
cin>>ans;
if (ans=='y' )
{
clock_t sTime, eTime;
sTime=clock();
system("pause" );
eTime=clock()-sTime;
char boundary[25][25];
int row, col;
//initalizes array to spaces

//makes left and right border

boundary[row][24]=219;
}
//places starting point of face

while (true )

if (GetAsyncKeyState(VK_LEFT) !=0 && boundary [row] [col - 1] ==' ' )

col-- ;
boundary [row] [col] =1;
}
if (GetAsyncKeyState(VK_RIGHT) !=0 && boundary [row] [col + 1] ==' ' )
{
boundary [row] [col] =' ' ;
col++ ;
boundary [row] [col] =1;
}
if (GetAsyncKeyState(VK_DOWN) !=0 && boundary [row + 1] [col] ==' ' )
{
boundary [row] [col] =' ' ;
row++ ;
boundary [row] [col] =1;
}
}
system("cls" );
for (int r=0; r<25; r++)
{
for (int c=0; c<25; c++)
{
cout << boundary[r][c] ;
}
cout << endl ;
}
getch();
cout<<"Time elapsed equals " <<double (eTime)/double (CLOCKS_PER_SEC);
}
else
{
return 0;
}
Any help would be greatly appreciated.

When I press y it just shows press any key to continue... and freezes. I have to click the red x to be able to close the console window. Using ans=getch();

Have you tried stepping through it in a debugger to see what's going on? Or putting in any debugging output?

Have a look at line 23. I think this is some special Microsoft trick to confuse programers?
