cannot convert from ‘const char *’ to ‘char *’ const char *c=aa.c_str(); string.c_str()只能转换成const char *, 要转成char *这样写: string mngName; char t[200]; memset(t,0,200); strcpy(t,mngName.c_str()); 版权声明:本文内容由互联网用户自发贡献,该文观点仅代表作者本人。...
thus even numbers are of string type for s = "3[a2[c]]" I want my loop to run the number of times that is returned by pop (2 and then 3 in this case), since the value returned by pop2() is of char type even after using atoi it doesn't work I tried doing int ...

How to convert a char array to a string? 使用string的c_str函数然后执行strcpy,将C ++string转换为char数组非常简单。 但是,相反的做法呢? 我有一个char数组,例如:char arr[ ] ="This is a test";要转换回: string str ="This is a test。
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 *' ...

///cstringTOchar* charpoint=strtest.GetBuffer(strtest.GetLength()); 标准C里没有string,char*==char[]==string 可以用CString.Format("%s",char*)这个方法来将char*转成CString。要把CString转成char*,用操作符(LPCSTR)CString就可以了。 CString转换char[100] ...
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。
