textwidth function in c graphics
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
int main(void) {
/* request auto detection */
int graphicDriver = DETECT, graphicMode;
int err, x = 0, y = 0;
char str[32];
/* initialize graphics and local variables */
initgraph(&graphicDriver, &graphicMode,
"C:/TURBOC3/BGI");
/* read result of initialization */
err = graphresult();
if (err != grOk) {
/* an error occurred */
printf("Graphic Error: %s",
grapherrormsg(err));
getch();
return 0;
}
/* moves CP to (10, 10) */
moveto(10, 10);
/* get x and y coordiante positions */
x = getx();
y = gety();
/* store the (x, y) positions in a string */
sprintf(str, "(x, y)=>(%d, %d) ", x, y);
/* outputs string at (x, y) */
outtextxy(x, y, str);
/* find the width of the input string in pixels */
x = x + textwidth(str);
outtextxy(x, y, "How Are You?");
/* clean up */
getch();
closegraph();
return 0;
}
Output: (textwidth built-in function in c graphics.h)
