VC中清屏和gotoxy()函数功能实现

#include <stdlib.h>
#include <stdio.h>
#include <windows.h>
void gotoxy(int x, int y)//x为列坐标,y为行坐标
{
COORD pos = {x,y};
HANDLE hOut = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleCursorPosition(hOut, pos);
}
void main()
{
char c;
printf("???????");getchar();
system("cls"); //清屏
gotoxy(10,5);printf("a=");c=getchar();
}
