将一组字符传递给函数

本文介绍了将一组字符传递给函数的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

很抱歉这个非常愚蠢的问题，但我显然还有很长的路要走！ 有人可以帮我把数组传递给一个函数。这是一个开始 点。 void TheMainFunc（） { //代码体... TCHAR myArray [512]; DoStuff（myArray）; } 无效DoStuff（TCHAR theArray） { ... } 我无法理解变量myArray的变化。是 - 它是一个 指向内存地址的指针，该内存地址可以容纳一个TCHAR（如果是 UNICODE则是一个宽字符）？ 谢谢 John - --- 如果你需要亲自回复，附加文字我的 电子邮件地址中的域名。 谢谢

Sorry for this very dumb question, but I''ve clearly got a long way to go! Can someone please help me pass an array into a function. Here''s a starting point. void TheMainFunc() { // Body of code... TCHAR myArray[512]; DoStuff(myArray); } void DoStuff(TCHAR theArray) { ... } I can''t quite get my head around what the variable "myArray" is - is it a pointer to a memory address that would hold a TCHAR (a wide char if UNICODE)? Thanks John -- --- If you need to reply personally, append "text" to the domain name in my email adr. Thanks

TCHAR myArray [512]; DoStuff（myArray）; } void DoStuff（TCHAR theArray） { ... } 我不能完全理解变量 myArray的"是 - 它是一个指向内存地址的指针，它将容纳一个TCHAR（如果是UNICODE则是一个宽字符）？ myArray是一个TCHAR数组。你的DoStuff函数接受一个参数 类型为TCHAR，即_one_字符。 尝试： void DoStuff（TCHAR * theArray ） Sorry for this very dumb question, but I''ve clearly got a long way to go! Can someone please help me pass an array into a function. You cannot pass arrays into functions. Usually, a pointer to the array''s first element is passed instead. Here''s a starting point. void TheMainFunc() { // Body of code... TCHAR myArray[512]; DoStuff(myArray); } void DoStuff(TCHAR theArray) { ... } I can''t quite get my head around what the variable "myArray" is - is it a pointer to a memory address that would hold a TCHAR (a wide char if UNICODE)? myArray is an array of TCHAR. Your DoStuff function takes a parameter of type TCHAR, i.e. _one_ character. Try: void DoStuff(TCHAR* theArray)

当你将数组传递给DoStuff时，它会自动转换为指向第一个元素的指针。

When you pass the array to DoStuff, it will be automatically converted into a pointer to its first element.

不，它'不是指针，它是256个实例存储的实际存储空间 TCHAR。但是你经常可能会把它称为指针，并且C是非常矛盾的，将数组变量名称转换为 指针，其中只有很少的挑衅非数组类型需要 运算符&得到指针。 C ++可能更愿意一直 需要运算符&，但与C一起兼容。

No, it''s not a pointer, it''s the actual storage for 256 instances of TCHAR. But you often may refer to it as if it was a pointer, and C is very ambivalent about that, converting the array variable name to a pointer with little provocation where non-array types would require operator& to get the pointer. C++ would probably prefer to consistently require the operator&, but goes along with C for compatibility.

当然可以吗？ ;-)

Sure about that? ;-)
