Need emergency help on c++ project

Hello
Im new to the forum and Im in need of help :/
I was asked to make a program that resemble a room with people trying to run out of it. To do this i was told to use matrix with 1s and 0s. I noticed a problem tho, where ppl "go out" of the matrix in the wrong place. I checked it a few dozen times but i just dont see, where the problem lies. I would greatly appreciate help and maybe a possible fix solution. If you help me i promise ill pray everyday for you, to whichever deity u wish

The problem is: "people" should go outside through "doors", which are 39-59 top-fields of the matrix. However some of them go through left side of the top of the matrix. (See the excel file to see what i mean)
Heres the code:

Code:

#include <stdio.h>
#include <math.h>
#include <stdlib.h>
#include <time.h>
void spawning();
void makeMoves();
int moveUp(int x, int y);
int moveLeft(int x, int y);
int moveRight(int x, int y);
int moveBiasLeft(int x, int y);
int moveBiasRight(int x, int y);
void goOutside(int x, int y);
void printingMatrixes();
int room[100][100];
int remaining = 0;
FILE* f;
FILE* g;
void main()
{
f=fopen("statistics", "wt");
g=fopen("graphs", "wt");
spawning();
fprintf(f, "\n\n");
while(remaining>0) 
{
makeMoves();
printingMatrixes();
}
printf("Press any key to terminate\n");
fclose(f);
fclose(g);
}
void spawning() //random spawns
{ 
int x, y, z;
srand((unsigned int)(time(NULL)));
for(y=0; y<100; y++)
for(x=0; x<100; x++)
{
z=rand()%10;
if(z==0)
{
room[x][y]=1;
fprintf(f, "%d, ", room[x][y]);
if(x==99) fprintf(f, "\n");
remaining++;
}
else
{
room[x][y]=0;
fprintf(f, "%d, ", room[x][y]);
if(x==99) fprintf(f, "\n");
}
}
}

int moveUp(int x, int y)
{

{

}

{

{

return 1;
}

}

{

{

room[x][y]=0;
return 1;
}
else return 0;
}
void goOutside(int x, int y)
{
room[x][y]=0;
fprintf(g, "%d, ", remaining);
remaining--;
}
void makeMoves()
{
int x,y;
int l_border = 39;
int r_border = 60;
for(y=0; y<100; y++)
for(x=0; x<100; x++)
{
if(room[x][y]==0) continue;
if(x<=l_border)
{
if(y==0) moveRight(x,y);
else if(moveBiasRight(x,y)==0) moveUp(x,y);
}
if(x>l_border&&x<r_border)
{
if(y==0) goOutside(x,y);
else
{
int val = 0;
val = moveUp(x,y);
if(val==0) val=moveBiasLeft(x,y);
if(val==0) val=moveBiasRight(x,y);
}
}
if(x>=r_border)
{
if(y==0) moveLeft(x,y);
else if(moveBiasLeft(x,y)==0) moveUp(x,y);
}
}
}
void printingMatrixes()
{
int x, y;
for(y=0; y<100; y++)
for(x=0; x<100; x++) 
{
fprintf(f, "%d, ", room[x][y]);
if(x==99) fprintf(f, "\n");
if(x==99&&y==99) fprintf(f, "\n\n");
}
}

Thanks in advance for any possible help and effort.
