Week Overview(1124)

  

float型参数不能直接传入数值，否则编译器不能判断它是double型还是float型

Write(string section , string key , float value)

Write(“Infor”,”Name”, 0.1);      //error

应传入float型变量

float p=0.1;

Write(“Infor”,”Name”, p);       //correct

 

子类不能用指针

SMConfig * m_config;

m_config=new SMConfig;

class SMConfig

{

       template<class T>

       class SectionWriter

       {

       }

}

 

m_config->SectionWriter<MAPS::value_type>(f); //error

SMConfig:: SectionWriter<MAPS::value_type>(f); //correct

 

free(buf)后buf!=NULL

 

不能直接把字符串常量赋值给char *

char * buf;

buf=(char *)malloc(256);

buf=”abc”;                //error, buf不是const char *,所以不能这样赋值

 

char * buf;

buf=(char *)malloc(256);

memcpy(buf,”abc”,3);

*(buf+3)=0          //0等于’/0’, 表示buf结尾，否则打印buf将打印abc及其后面的乱码

 

EA的用法

Project->Version Control->Work Offline

project view, 双击main, 右键check out，就可在本地改动文件了

画箭头:选中testcase的方框，再选中tool box中custom下 Dependency，从testcase方框内拖到函数方框内

画diagram frame: 右键 Insert element at cursor->diagram frame

把函数从Class Model模块下拖到Test Model模块下

toolbox下 custom->testcase, 右键 Advanced Settings->use rectangle notation
