代码如下：class Program { static void Main(string[] args) { double datax = 2356987.2156;//声明double类型datax int datay = Convert.ToInt32(datax);//使用convert关键字进行转换 Console.WriteLine(datay);//输出整型变量datay Console.ReadLine(); } }结果与上例一样：值...
var pUInt8 = CPointer<UInt8>(pInt8) // CPointer<Int8> convert to CPointer<UInt8> 0 } 仓颉语言支持将一个 CFunc 类型的变量类型转换为一个具体的 CPointer,其中 CPointer 的泛型参数 T 可以是满足 CType 约束的任意类型,使用方式如下: 收起 深色代码主题 复制 foreign func rand(): Int32 main...

如对于：const char * GetString(void);如下语句将出现编译错误：char *str = GetString();//cannot convert from 'const char *' to 'char *'；正确的用法是：const char *str = GetString();b.如果函数返回值采用“值传递方式”，由于函数会把返回值复制到外部临时的存储单元中，加const修饰...
