头文件显示图形。h包含 gety() 函数返回当前位置的Y坐标。 语法:
null
int gety();
例子:
说明: 最初,当前位置的Y坐标为0。关于使用 moveto() 函数,Y坐标变为50。
下面是gety()函数的实现:
// C Implementation for gety() #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; char arr[100]; // initgraph initializes the // graphics system by loading a // graphics driver from disk initgraph(&gd, &gm, "" ); // sprintf stands for “String print”. // Instead of printing on console, it // store output on char buffer which // are specified in sprintf sprintf (arr, "Current position of y = %d" , gety()); // outtext function displays text at // current position. outtext(arr); // moveto function moveto(80, 50); sprintf (arr, "Current position of y = %d" , gety()); // 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; } |
