The header file graphics.h contains getmaxx() function which returns the maximum X coordinate for current graphics mode and driver.
Syntax :
int getmaxx();
Below is the implementation of getmaxx() function:
// C Implementation for getmaxx() #include <graphics.h> #include <stdio.h> // driver code int main()
{ // gm is Graphics mode which is
// a computer display mode that
// generates image using pixels.
// DETECT is a macro defined in
// "graphics.h" header file
int gd = DETECT, gm;
char arr[100];
// initgraph initializes the
// graphics system by loading a
// graphics driver from disk
initgraph(&gd, &gm, "" );
// sprintf stands for “String print”.
// Instead of printing on console, it
// store output on char buffer which
// are specified in sprintf
sprintf (arr, "Maximum X coordinate for current "
"graphics mode And driver = %d" , getmaxx());
// outtext function displays text at
// current position.
outtext(arr);
getch();
// closegraph function closes the
// graphics mode and deallocates
// all memory allocated by
// graphics system .
closegraph();
return 0;
