我在练习一个例题程序(如下)的时候,用VC可以成功编译,但是组建的时候出错误,而用TC可以成功运行该程序.我们老师告诉我们VC编译器对C语言是完全兼容的,但是为什么会出现我遇到的情况呢?谢谢各位解答.
例题程序:
#include<conio.h>
main()
{
int color;
for(color=0;color<8;color++)
{
textbackground(color);
cprintf("This is color %d\r\n",color);
cprintf("press anykey to continue\r\n");
getch();
}
}

兼容应该说是兼容的...不过不可能会完全一样

你看vc6.0的conio.h里根本没有textbackground函数的原型定义...其他cprintf是有的...
