当您从obj创建str时,编译器不会抛出错误,因为我们已经定义了 Conversion 运算符。 当您设置obj = 20时,您实际上是在调用转换构造函数。 当您从static_cast中生成str2时,它与 string str = obj非常相似;但有严格的类型检查。 当您编写obj = static_cast <Int> (30)时,您使用 static_cast将 30 转换为integ...
Now, let's focus on some examples to further understand about type conversions in C.Example 1int a = 20; double b = 20.5; a + b; Here, first operand is int type and other is of type double. So, as per rule 2, the variable a will be converted to double. Therefore, the final ...

Here, Integer is a wrapper class in Java. To learn more, visit the Java Wrapper Class. Note: The string variables should represent the int values. Otherwise the compiler will throw an exception. For example, class Main { public static void main(String[] args) { // create a string variab...
