C 中对 Gotoxy 的未定义引用

我正在尝试用 C 语言编写一个程序（Windows 中的 code::blocks）。 我添加了下面的头文件，它编译时没有错误，但是当运行代码时，它会抛出一个错误，未定义对 Gotoxy 的引用。 找到完整的代码。 只要我有 Gotoxy 语句，就会出现错误。

请帮我。

您遇到的问题与以下问题无关Code::Blocks，它与它使用的编译器（默认为 MinGW）有关，这是因为该函数不是标准的，并且没有在该编译器中实现。我不确定 Borland 是否还提供conio.h，但你可以尝试this one for MinGW.

看看这个http://projectsofashok.blogspot.in/2010/05/gotoxy-in-codeblocks.html

您还可以尝试下面的代码片段，这将在海湾合作委员会工作

#include<stdio.h>
//gotoxy function
void gotoxy(int x,int y)
{
printf("%c[%d;%df",0x1B,y,x);
}
main ()
{
gotoxy(25,50); //reposition cursor
printf("hello world"); //display text
}
