i want to write the symbol of Degrees in Centigrade "180oC', and i use ASCII code to write the "o" symbol, but ...
printf( "180%cC", chr(167) );
when i execute the c program, the error say "undefined reference to `chr'", what can i do ??

Don't put the chr(). Use this:
printf("180%cCCC",167);
The correct typecast is (char), not chr(). But you don't need it here anyway; the output format (as a character rather than a numeral) is taken care of by the format specifier %c in printf().
if i use this "printf("180%cC",167);"
the output in dos mode is "180’á", has a chinese word behind 180,
but if i copy the output to windows, it's OK, can see the symbol, why ?? what can i do ??
Try making a variable and using that.
int symbol=167;
printf("180%cC",symbol);
That might work. Doing it how I said earlier worked for me.

It's not an ASCII character (these run from 32 to 127). Anything else is subject to the vagaries of compilers / operating systems / fonts.
Unless you're using UNICODE in an environment which supports it, then you might fare better.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Maybe 176.
