// 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();
  
    return 0;
