in_array(0,['a','b','c'])// 返回bool(true),相当于数组中有0array_search(0,['a','b','c'])// 返回int(0),相当于是第一个值的下标0=='abc'// 返回bool(true),相当于等值 但是,直观上看, 0并没有包含在['a', 'b', 'c']数组中,也不会等于'abc'这个字符串。那怎么解释上述的返...
它们是不会转换成int型的,所以结果是这样的: in_array(null, ['a','b','c'])//返回false in_array(false, ['a','b','c'])//返回false 4 数组中有true 还有另外一个看起来比较奇怪的现象: in_array('a', [true,'b','c'])// 返回bool(true),相当于数组里面有字符'a' array_search('a'...

excess elements in char array initializer 的意思是：在char数组初始化时，设置了多余的元素。如：const char ChDay[] = { //这里定义的是一个一维字符数组，并进行初始化，一维数组的元素只能是单个的字符，而下面的数据却是字符串，所以，在编译时会报错误。"","初一","初二","初三","初四"...

If the items in the CArray are not compatible with memcpy_s, you must create a new CArray of the appropriate size. You must then use CArray::Copy and CArray::SetAt to populate the new array because those methods use an assignment operator instead of memcpy_s. As with a C array, ...
If parts of newlib are going to be replaced with an external library (such as withlibgloss-htiffor Berkeley Host-Target Interface), you should take care to ensure that both newlib and the external library are built using the same code model. For more information about RISC-V code models,re...
