头文件显示图形。h包含 outtext() 在当前位置显示文本的函数。
null
语法:
void outtext(char *string);
例如:
Input : string = "Hello Geek, Have a good day !" Output :Input : string = "GeeksforGeeks is the best !" Output :
![]()
注: 在图形模式下工作时,不要使用文本模式功能,如printf。确保使用outtext时文本不会超出屏幕。
下面是outtext()函数的实现:
// C Implementation for outtext() #include <graphics.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; // initgraph initializes the // graphics system by loading a // graphics driver from disk initgraph(&gd, &gm, "" ); // outtext function outtext( "Hello Geek, Have a good day !" ); getch(); // closegraph function closes the // graphics mode and deallocates // all memory allocated by // graphics system . closegraph(); return 0; } |
