Turbo C Graphics - moveto function

---

moveto function is used to move the current graphics cursor position to a particulat location. It accepts two input parameters - xpos and ypos.

 

outtext is the function used to display the given string on graphics mode. It uses the font style set by settextstyle and the current position. The current position can be changed with moveto function. Alternatively you can use outtextxy function which takes xpos, ypos and string for displaying at a particular location. outtextxy does the work of both moveto and outtext functions.

 

In this example, the string "background: %d, foreground: %d, maxcolors:%d" is displayed using outtext and softwareandfinance.com is displayed using outtextxy.
