textheight() function in C

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

int textheight(char *string);

Example :

Output : 

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.
    // closegraph function closes the
    // graphics mode and deallocates
    // all memory allocated by
    // graphics system .
    return 0;
