Hey guys, I'm in a high school programming class with a teacher that doesnt know how to teach it. (the other guy who used to teach it switched to the math department) so expect me to ask a lot of questions. currently, we are working on a snake game program (in turbo C++ 3 for DOS, dear god.) and i need to merge the following two programs that i've written in order for it to do something new. here's the directions from the top of the sheet:

"Delete the code that places the prize on the screen from program "snake5a.cpp" and insert the do..while loop from this program. This should prevent the prize showing up on a spot when the snake part is already there. Then, change the program so a number from 1 to 9 shows up instead of an X. If the snake reaches the prize, the snake should increase in length by the same number as the prize. The score should also increase by the number of the prize. Finally, change the program so that the program ends when the snake head hits a part of the snake."

Here's snake5a:

(Toggle Plain Text)

#include <conio.h>
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <dos.h>

void main()
{
	clrscr();
	int snakex[500],snakey[500],prizex,prizey;
	int timer,length,a;
	char dir,temp;

	_setcursortype(_NOCURSOR);
	timer=0;
	length=10;

	for(a=0;a<=length-1;a++)
	{
		snakex[a]=40;
		snakey[a]=10;
	}

	gotoxy(snakex[0],snakey[0]);
	printf("0");
	dir='2';

	for(a=19;a<=61;a++)
	{
		gotoxy(a,4);printf("*");
		gotoxy(a,21);printf("*");
	}
	for(a=4;a<=21;a++)
	{
		gotoxy(19,a);printf("*");
		gotoxy(61,a);printf("*");
	}	


	do
	{
		randomize();
		if(timer==0)
	{
	
		gotoxy(prizex,prizey);
		printf(" ");
		prizex=rand()%40+20;
		prizey=rand()%15+5;
		gotoxy(prizex,prizey);
		printf("X");
		timer=100000;
	}
	else timer=timer-1;

	delay(100);

	if(kbhit()!=0)
	{
	temp=getch();
	if(dir=='4'||dir=='6'||dir=='8'||dir=='2'||dir=='0') dir=temp;
	if(dir=='4'||dir=='6'||dir=='8'||dir=='2')
	{
	gotoxy(snakex[length-1],snakey[length=1]);
	printf(" ");
	for(a=length-1;a>=1;a--)
	{
		snakex[a]=snakex[a-1];
		snakey[a]=snakey[a-1];
	}
	}
	if(dir=='4')  snakex[0]--;
	if(dir=='6')  snakex[0]++;
	if(dir=='8')  snakey[0]--;
	if(dir=='2')  snakey[0]++;
	gotoxy(snakex[0],snakey[0]);
	printf("0");

	if(snakex[0]&&snakey[0]==prizex&&prizey)
	{
		length=length+5;
	}

	if(snakex[0]>=61||snakex[0]<=19||snakey[0]>=21||snakey[0]<=4)
		{
		dir = '0';
		gotoxy(36,12);
		printf("Game Over.");
		}

		}
		delay(1000);
	}while(dir!='0');
}

and heres snake6a:

(Toggle Plain Text)

#include <conio.h>
#include <stdio.h>
#include <time.h>
#include <stdlib.h>
#include <dos.h>

void main
{
	clrscr();

	int snakex[400],snakey[400],prizex,prizey,a,length,same;

	length=10;
	_setcursortype(_NOCURSOR);

	do
	{
	gotoxy{prizex,prizey);
	printf(" ");
	prizex=rand()%40 + 20;
	prizey=rand()%15 + 5;
	same=0;
	for(a=0;a<-length-1;a++)
	{
	if(prizex==snake[a]&&prizey==snakey[a]) same=1;
	}
	{while(same==1);

	gotoxy(prizex,prizey);
	printf("X");
	getch();
}

So...what do I do!? Please help mighty programming gods.

Welcome, I see you have been so kind to post in code tags, very good, but you should read the whole "how to post a question" thread.

You need to specify what works and what doesn't.

Also try to be concise. A small complete example is often better, I did not take a look at your code yet, so it might not be wrong of you to post it all.
