In this article, we will be focusing on the different ways toconvert String to char array and char array to String inC.While dealing with String data, we may need to convert the string data items to character array and vice-versa. This tutorial will help you solve exactly that. 在本文中...
使用CString的GetBuffer方法 CString origCString("Hello,World"); char* CharString = origCString.GetBuffer(origCString.GetLength()+1); 网上的很多文章说的都是这个方法,但是我在VC++2005中编译得到下列信息 : Error 1 error C2440: 'initializing' : cannot convert from 'wchar_t *' to 'char *' 对于这...

用法:char *itoa(int value, char *string, int radix); 详细解释:itoa是英文integer to array(将int整型数转化为一个字符串,并将值保存在数组string中)的缩写. 参数: value: 待转化的整数。 radix: 是基数的意思,即先将value转化为radix进制的数,范围介于2-36,比如10表示10进制,16表示16进制。
提示string类型直接赋值给char* 错误: error C2440: '=' : cannot convert from 'const char *' to 'char *' 更正方法: 将char* 定义为 const char* 即可. 代码: string imbagFilePath="G:\\WorkSpace\\FileOperation\\fluor1_AjaxOrange_078.imbag"; ...

error: cannot convert 'char**' to 'char*' in initialization for strings I am making C console menu program. And I am stuck with the char* assignment. Is there any good method to assign char* to char**? The code is as below:
String text1; What I do not understand is why c_str() works, const char *text2 = text1.c_str(); contrary to toCharArray()? const char *text2 = text1.toCharArray(); or const char text2 = text1.toCharArray(); The latter is more logical to me as I want to convert a ...
类型错误，多是你把一个二维数组名传给一个指向某种数据类型的指针 要传递也是传递给指向指针的指针
