This gives the error: cannot convert from 'const char *' to 'char *'. class Mock { public: ... static void func(char **result) { *result = (resultsI++)->c_str(); } static std::vector<std::string> results; static std::vector<std::string>::iterator resultsI; }; s...
解决方法: 方法一: 菜单栏->project->xxx properties->Configuration Properties->General->Character Set,改成“not set”或改成“Use Multi-Byte Character Set”。 方法二: 在const char前加上_T宏,进行转换。 例如:_T("编码器设置错误,请稍后再试!")。 使用_T宏,要加上tchar.h头文件,不然编译会报错: ...
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"; const char *cImBagFilePath=new char[200];//...
char * strchr(const char *cs, char c)改为char * strchr(char *cs, char c)试试。因为return cs+i的时候,cs+i是const char *的,原先的返回值是char *类型。
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 }

char expression[]等价于char * expression,而'('属于字符常量,这个赋值显然是不行的。可以将之改为char expression[]="(";
