对了，Visual C++中，是不是没有gotoxy和clrscr函数啊，我编这个乘法口诀表#include <stdio.h>
#include <conio.h>
void main()
{
int i,j,x,y;
clrscr();
printf("\n\n***Pithy Formula Table of Multiplication***\n\n");
x=9;
y=5;
for(i=1;i<=9;i++)
{
gotoxy(x,y);
printf("%2d",i);
x+=3;
}
x=7;
y=6;
for(j=1;j<=9;j++)
{
gotoxy(x,y);
printf("%2d",j);
y++;
}
x=9;
y=6;
for(i=1;i<=9;i++)
{
for(j=1;j<=9;j++)
{
gotoxy(x,y);
printf("%2d",i*j);
y++;
}
y-=9;
x+=3;
}
printf("\n\n Press any key to quit...\n");
getchar();
} 乘法口诀法.obj : error LNK2001: unresolved external symbol _gotoxy
乘法口诀法.obj : error LNK2001: unresolved external symbol _clrscr
Debug/乘法口诀法.exe : fatal error LNK1120: 2 unresolved externals
执行 link.exe 时出错.
这是怎么回事啊？
