指针值传递和地址传递 指针的指针参数传递？

指针的指针参数传递？

调用函数时，它使用实际参数而不是形式参数，并贯穿函数体的整个过程。值可以通过实际参数传递到函数体，处理后的值只能通过带回调的指针参数传递，也可以通过全局数量传递。参数voidfun（char*a[]）{char*P=“add”a[1]=P}是指针数组，它实际使用指针数组中的第二个指针元素a[1]。“Add”是一个字符串常量，通过本地数量（指针）P传递给a[1]，它等价于：voidfun（char*a[]）{a[1]=“Add”}================================================================================================================================================= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = =
