The header file graphics.h contains textheight() function which returns the height of input string in pixels.
Syntax :

Below is the implementation of textheight() function.
// 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; } |
Output :
