maximum and minimum

This is a discussion on maximum and minimum within the C Programming forums, part of the General Programming Boards category; You can't print them in the same place as your x axis! You have to change the coordinates in Putstr ...

    You can't print them in the same place as your x axis! You have to change the coordinates in Putstr around so that you print up the y-axis, not across the x-axis. And if you want 0 to be special, do it outside the loop (so that you would start n at 1 instead of 0).

    Okay I have tried to change my coorinate but it did not help.

    Code:
    #include <stdio.h>
    #include <string.h>
    
    char xText[] = "Tid(sek)";
    char yText[] = "Temp(C)";
    
    char a[16][45] =
    {
    		{"                                             "},
    		{"                                             "},
    		{"              ^                              "},
    		{"              |                              "},

    Again, you are printing six things inside the loop, which happens six times, for a grand total of thirty-six different things printing. You need to print one thing inside the loop, which happens five times (since you seem to want to do 0 special, so that would go before the loop).

    Just because you are doing the same thing that you did with the x-axis does not mean you have to make the same mistakes along the way. This was a merely silly thing to do the first time -- now that you know better, and have the right answer (more or less) already in your code, to do the same thing again is stupid.

    Okay, but when I try with almost the same loops I used in the x-axe, does it still not work:

    Code:
    for(n = 0; n < 6; n++)
    	{
    		char s[32];
    		sprintf(s, "%.1f", ((maxx-minx)/5)*n);
    		Putstr(13 + 4*n, 14 + (n % 2), s);
    	}
    
    for(n = 0; n < 6; n++)
    	{
    		char s[32];
    		sprintf(s, "%.1f", ((maxy-miny)/5)*n);
    		Putstr(10 + 4*n, 14 , s);
    	}

    You cannot change the Putstr coordinates at random! And even besides that, you are still going across, not up. Your coordinates were supposed to be (8,11), (8,9), (8,7), (8,5), (8,3) for n = 1 through 5. Do you think 10+4*n will give you 8, 8, 8, 8, and 8? Do you think that a y-coordinate that is 14 will somehow give you 11, 9, 7, 5, and 3?
