C在傳遞資料進function時,就只有兩招,一招是call by value,一招是call by address(實際上也是一種call by value,只是它copy的是value的address,而不是value本身),一些較小型的型別如int、double,我們會使用call by value配合return,當然使用call by address亦可;而一些較大的型別,如string、array、struct,我們會...
A function-call expression has the value and type of the function's return value. A function can't return an object of array type. If the function's return type is void (that is, the function has been declared never to return a value), the function-call expression also has void type...
The simple answer to this first question is that a callback function isa function that is called through a function pointer.If you pass the pointer (address) of a function as an argument to another, when that pointer is used to call the function it points to it is said that a call bac...
In this example, the function call inmain, work( count, lift ); passes an integer variable,count, and the address of the functionliftto the functionwork. Note that the function address is passed simply by giving the function identifier, since a function identifier evaluates to a pointer expre...
11、 Extra parameter in call ‘fun’ 调用函数fun时给出了多余的实参。 12、 Function should return a value 函数应该返回一个值,否则与定义时的说明类型不匹配。 13、 Illegal use of pointer 指针被非法引用,一般是使用了非法的指针运算。 14、 Invalid pointer addition 指针相加非法。一个指针(地址)可以和...

为了简化,我们可以为 printf 定义 FunctionDescriptor 的简化版本: FunctionDescriptorprintfDescriptor=FunctionDescriptor.of(JAVA_INT,ADDRESS); 注意:从 Java 运行时的角度来看,C 指针背后的值类型无关紧要,因为 C 指针的内存布局不保存类型,而是平台固定的 32/64 位值。
