// C Implementation for textheight()
#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, color, height;
char arr[100];
// initgraph initializes the
// graphics system by loading a
// graphics driver from disk
initgraph(&gd, &gm, "");
// textheight function
height = textheight("Hello Geek ! Have a good day.");
//sprintf stands for “String print”.
//Instead of printing on console,
//it store output on char buffer
//which are specified in sprintf
sprintf(arr, "Textheight is = %d", height);
//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();
