Alright, i've got a problem! my program reads a text file that has x and y co-ordinates for a number of points on a graph, i can read the file ok, but need to find the max and min values for x and y thats where it goes wrong!
this is what i'e got:

Code:
```void getPoints(void)
{

char buf[100];
int length =0;
int a;
int b;
int v=0;
int i =0;

FILE *stream;
if ((stream = fopen("Points.txt","r")) == NULL)
{
fprintf(stderr,"Error opening file.");
exit(1);

}

while(!feof(stream))
{
fgets(buf,30,stream);
if (sscanf(buf,"%d %d", &a,&b))
{
pointX[i] = a;
pointY[i] = b;
i++;
}
}
Max_X = pointX[0];
Min_X = pointX[0];
Min_Y = pointY[0];
Max_Y = pointY[0];

for(v=2;v=35266;v++)
{
if(Max_X < pointX[v] ) Max_X = pointX[v];
if(Min_X > pointX[v] ) Min_X = pointX[v];
if(Max_Y < pointY[v] ) Max_Y = pointY[v];
if(Min_Y > pointY[v] ) Min_Y = pointY[v];

}

}```
i cann't get it to scan through all the coordinates correctly. any help appreciated!

2. It seems ok. How do you declare pointX and pointY? Perhaps your indexes are wrong (an array with n elements range from 0 to n-1)?

3. declared like this:
Code:
```int pointX[36000];
int pointY[36000];
int Max_X,Min_X,Max_Y,Min_Y;```
when i compile the max values have some random number in them and te min values are always 0,

4. As always, the error is right in front of the nose .
Code:
`for(v = 2; v = 35266; v++)`
Should be
Code:
`for(v = 2; v < 35266; v++)`
(Why start at 2? That's the third element)

If that wasn't the problem, perhaps you're compiling in a 16-bit compiler? Integers then range from ~ -32000 to +32000, making it impossible to address 35266.
