System Pause Error please help

[QUOTE]#include<stdio.h>

int main () {
int i,j,max_c, max_j;

    FILE * fin;

    fscanf(fin,"%d", &num_shows);
    printf("%d\n",num_shows);

//int scores[max_c][max_j];

    fclose(fin);

system("PAUSE");

I am trying to write a code but I keep getting an error with the system pause. I cant seem to figure it out. Even for other codes I have been trying to write.

Don't use system("PAUSE")

For my class our teacher told us to. This is the only way we learned how to keep the output window open

What error?

I cant seem to figure it out.

I can't either, because you didn't tell me what error you got.

#include<stdilb.h>
#include<stdio.h>
int main( void )
{
    system( "pause" );
    printf( "error?\n" );
    return 0;
}

If you don't get an error there, then system isn't your problem. So, what error are you getting?

//int scores[max_c][max_j];
    //for(i=1;i<=max_c;i++)
        //fscanf(fin,"%d",&max_c);
    //for(j=1;j<=max_j,j++)
        //fscanf(fin,"%d",&max_j);

Also Im not too good with arrays. If I want to read in from a file and store the numbers as an array would this be close?

[quzah]

See the top two lines of my example? Those are #include directives. They basically say "use the following file". stdlib.h is required for the use of the system function.

Anytime you see 'X is undeclared', it means you are either trying to call a function or variable that it knows nothing about. It doesn't know anything about it, because it only knows about what is above it in the file. If you haven't included the appropriate headers at that point, it knows nothing of what the hold.

edit - for your array edit question

Arrays are basically like drawers in a cabinet. Each drawer holds whatever type the array is. The drawers of an array of integers each store one integer:

int array[ 5 ];

This would have five drawers, each one holding one int. To put something in one directly:

array[ 2 ] = 12345;

To put something in with say, scanf, we can do:

scanf( "%d", & array[ 2 ] );

To put something in each drawer in a loop:

int x = 0;
for( x = 0; x < 5; x++ )
    scanf( "%d%*c", & array[ x ] );

Or something to that effect.

#include stdlib.h

ok thanks that helped...its weird I have never used the standard library but I have always used system pasue

Well, for future... everything that's not a C keyword is either part of the standard library or something you wrote...
