'0'=0x30'1'=0x31'2'=0x32'3'=0x33'4'=0x34'z'=0x7A'+'=0x2B在VC6.0下测试，结果很有意思int m='01';//m=0x3031int m='012';//m=0x303132int m='0+1';//m=0x302B31int m='z+4';//m=0x7A2B34但是如果定义int m='12345',就会报错“error C2015: too many characters in constant”。从以上可以看出，形如int m=‘ABCD';这样的格式（注意是单引号，不是双引号，双引号就是字符串了），VC6.0的编译器...
