注：
1、CCVector实现： http://blog.csdn.net/cxsjabcabc/article/details/7302423
2、CC_ASSERT宏的定义：
#ifdef _WINDOWS
#define CC_ASSERT(var, msg) \
{ \
CCString strTemp19870814_neverUsed; \
char line[32] = {0}; \
strTemp19870814_neverUsed += __FILE__, strTemp19870814_neverUsed += " Line:", itoa(__LINE__, line, 10), strTemp19870814_neverUsed += line; \
if(!(var)) COUT_2_VAR_ENDL(strTemp19870814_neverUsed.pointer(), (msg)) \
else COUT_LINE("OK!") \
}
#define CC_ASSERT_EQUAL(var1, var2, msg) \
{ \
CCString strTemp19870814_neverUsed; \
char line[32] = {0}; \
strTemp19870814_neverUsed += __FILE__, strTemp19870814_neverUsed += " Line:", itoa(__LINE__, line, 10), strTemp19870814_neverUsed += line; \
if((var1) != (var2)) COUT_2_VAR_ENDL(strTemp19870814_neverUsed.pointer(), (msg)) \
else COUT_LINE("OK!") \
}
#else
#define CC_ASSERT(var, msg) \
{ \
CCString strTemp19870814_neverUsed; \
char line[32] = {0}; \
strTemp19870814_neverUsed += __FILE__, strTemp19870814_neverUsed += " Line:", sprintf(line, "%d",__LINE__), strTemp19870814_neverUsed += line; \
if(!(var)) COUT_2_VAR_ENDL(strTemp19870814_neverUsed.pointer(), (msg)) \
else COUT_LINE("OK!") \
}
#define CC_ASSERT_EQUAL(var1, var2, msg) \
{ \
CCString strTemp19870814_neverUsed; \
char line[32] = {0}; \
strTemp19870814_neverUsed += __FILE__, strTemp19870814_neverUsed += " Line:", sprintf(line, "%d",__LINE__), strTemp19870814_neverUsed += line; \
if((var1) != (var2)) COUT_2_VAR_ENDL(strTemp19870814_neverUsed.pointer(), (msg)) \
else COUT_LINE("OK!") \
}
#endif
3、COUT_LINE和COUT_2_VAR_ENDL宏的定义：
#define COUT_LINE(str) std::cout << (str) << std::endl;
#define COUT_2_VAR_ENDL(str1, str2) \
std::cout << (str1) << " " << (str2) << std::endl;微风不燥，阳光正好，你就像风一样经过这里，愿你停留的片刻温暖舒心。
