C语言函数说明 中文 均配以范例 很全面

C语言函数说明 函数名: getx 功 能: 返回当前图形位置的x坐标 用 法: int far getx(void); 程序例: #include <graphics.h> #include <stdlib.h> #include <stdio.h> #include <conio.h> int main(void) { /* request auto detection */ int gdriver = DETECT, gmode, errorcode; char msg[80]; /* initialize graphics and local variables */ initgraph(&gdriver, &gmode, ""); /* read result of initialization */ errorcode = graphresult(); if (errorcode != grOk) /* an error occurred */ { printf("Graphics error: %s\n", grapherrormsg(errorcode)); printf("Press any key to halt:"); getch(); exit(1); /* terminate with an error code */ } /* move to the screen center point */ moveto(getmaxx() / 2, getmaxy() / 2); /* create a message string */ sprintf(msg, "<-(%d, %d) is the here.", getx(), gety()); /* display the message */ outtext(msg); /* clean up */ getch(); closegraph(); return 0; }
