我尝试了以下

printf ("%c", 236);   //236 is the ASCII value for infinity

但我只是在屏幕上得到垃圾输出。

printf 对于小于 128 的 ASCII 值可以正常工作。所以我尝试了以下 

printf ("%c", 236u);  //unsigned int 236

我仍然只是得到垃圾。那么，我应该怎么做才能让 printf 显示从 128 到 255 的 ASCII 值。

Standard C does not have a symbol for infinite. That's for your implementation (eg. your compiler, your operating system, your terminal and your hardware) to define. Consider that C was designed with portability for systems that use non-ASCII character sets in mind (eg. EBCDIC).
