其中int表示64位整数类型,double表示双精度浮点数。...double y = 20.12; y = 40; 在Dart语言中有一个num类型,该类型既可以表示int类型,也可以表示double类型。...,结果是63 print('x.bitLength = ${x.bitLength}'); double y = 20.4; // 输出变量y,其中通过$可以在字符串中嵌入变量,...
charpoint="give string a value"; strtest=charpoint;///cstring TO char *charpoint=strtest.GetBuffer(strtest.GetLength()); 标准C里没有string,char*==char[]==string可以用CString.Format("%s",char*)这个方法来将char *转成CString。要把CString转成char *,用操作符(LPCSTR)CString就可以了。
