I am trying to create a fork/exec call from a parent program via a passed '-e' parameter (e.g. parent -e child key1=val1 ...). As a result I want to copy all the values after the first two in the argv array into a new array child_argv. Something like: const char *child...
one other problem is how to destroy the const char*, i tried: prettyprintCopy const char *ncharInputFile = convtCStrToChar(m_szlstfile); const char* CSVMTrainDlg::convtCStrToChar(CString strParam) { CStringA cstraParam(strParam); const char *ncharStr(cstraParam); return ncharStr;...
你传入strcmp的第一个参数是char**类型,所以报错。在第一个参数前再加上*即可编译通过。
error: cannot convert ‘const char (*)[5]’ to ‘char*’ in initialization 原因 如果只给出一个字符串,那么会默认为它的类型是 const char *,是一个常量类型。 而指针无法指向一个常量的地址,所以不能这样写。 解决方法 ①定义一个字符数组,让p指向它的首地址: ...
Hi, I got this error: cannot convert 'const char*' to 'LPCWSTR {aka const wchar_t*}' for argument '1' to 'void* FindFirstFileW(LPCWSTR, LPWIN32_FIND_DATAW)' HANDLE dir = ::FindFirstFile((cur_path + "/*").c_str(), &find_data); ^ from the ...
强制转换下,就ok了 include <stdio.h> void main( void ){ const char *str1="hello";char *str2;str2=(char *)str1; ///强制转换下,就ok了 }
