    weird question

    Code:
    #include <stdio.h>
    #include <string.h>
    #include <stdlib.h>
    
    	int number, flag=1;
    	int w,h,n;
    
    	int tall,wide,position,x=0,y=0,a=0;
    	char line[50],common[50];
    	FILE *ifp;
    
    void readfile();
    
    main()
    {
    	int x;
    
    	while(x!=0)
    	{
    		printf("\n (1) ReadFile Function\n  ");
    		scanf("%i",&x);
    
    		if (x==1)
    		{
    			readfile();
    			
    		}
    	}
    }
    
    
    void readfile()
    {
    
    	if ((ifp=fopen("objects.dat", "r")) == NULL)
    	{
    		printf("\n  * error opening file objects.dat *");
    	}
    
    	fgets(line,100,ifp);
    	position=(strlen(line)-1);
    
    	while (position>0)
    	{ 
    		if(line[x]==' ')
    		{     number++;    }
    		position--; x++;
    	}
    		
    	number+=1; x=0;
    
    	while (number>0)
    		{	
    			
    			if(line[y]=' ')
    			{
    				if (flag==5)
    				{
    					n=atoi(common);  flag+=1;  common==0;  x=0;  number--;  break;
    				}
    				
    				if (flag==4)
    				{
    					h=atoi(common);  flag+=1;  common==0;  x=0;  number--;
    				}
    				
    				if (flag==3)
    				{
    					w=atoi(common);  flag+=1;  common==0;  x=0;  number--;
    				}
    				
    				if (flag==2)
    				{
    					tall=atoi(common); common==0; flag+=1; x=0;   number--; break;
    				}
    
    				if (flag==1)
    				{
    					wide=atoi(common);  flag+=1;  common==0;  x=0;  number--;
    				}
    			}
    
    			common[x]=line[y];
    			y++; x++;
    		}
    	
    	printf("\n Number 1: %i",wide);
    	printf("\n Number 2: %i\n\n\n",tall);
    }
    this was a function i wrote today but it isn't working properly........it's just telling me Number 1 and 2 = 0.....can anyone run this and tweak with it and an "objects.dat" file to try to make it work?? i know it looks odd but can anyone mess with it real fast? Thanks.

    The first problem is that you defined 'x' globally and set it equal to 0, so it will never enter the while loop in main. If I get time later I'll try to look at it some more.

    See ya

    Unnecessary, global variables are initialized the their equivalent of all bits zero automatically.

    >if(line[y]=' ')
    Oopsie, assignment inside a conditional. You probably meant ==, not =.

    My best code is written with the delete key.
