# 编译器首先会报warning warning: ‘sizeof’ on array function parameter ‘array’ will return size of ‘int*’ 意味着sizeof(array)并不能像主函数中一样得到数组的总占用内存, 而是把array认为是一个int型的指针, 从而计算了int型指针的size 看一下结果: In Func main, length of array = 4 # ...
However, the full declaration of the array is needed in the function parameter (int myNumbers[5]).Return ValuesThe void keyword, used in the previous examples, indicates that the function should not return a value. If you want the function to return a value, you can use a data type (...

func_get_arg() gets the value of an individual parameter. func_get_args() returns an array of the parameters that were passed in. 1. 2. 3. 4. 5. 6. 7. 这里举个例子: function some_func($a, $b) { for ($i = 0; $i < func_num_args(); ++$i) { ...
Some solutions to use output parameter and copy the value of the array into the value of this output parameter array. Other solution to pass an array and use it inside the function. 一些解决方案是使用数组作为输出参数,并将值复制到这个参数。
element of the array, provided that the array has previously been declared. An array type in the parameter list of a function is also converted to the corresponding pointer type. Information about the size of the argument array is lost when the array is accessed from within the function body...
