Short story about swapping bodies as a job; the person who hires the main character misuses his body. c++ - How can I convert const char* to char[256] - Stack Overflow When you have non-const pointer, you can allocate the memory for it and then use strcpy (or memcpy) to copy the string itself. What differentiates living as mere roommates from living in a marriage-like relationship? cannot convert 'const char **' to 'const char*'. Well, you allocate the structure, but not the string inside the structure. How about saving the world? @keanehui1 no. Connect and share knowledge within a single location that is structured and easy to search. char * function (void); struct myStruct { const char *myVal; }; int main (int argc, char *argv []) { char *value = function (); struct myStruct *s = malloc (sizeof (struct myStruct)); s->myVal = value; // I want to be able to assign the value and // immediately free value as per the next line. This is considered bad practice, but you should think of const as a strong suggestion of the original programmer, not to modify it. To learn more, see our tips on writing great answers. If you'd be able to assign the same pointer to str0 you'd break the const contract; str0 can be modifiable. My solution: char *argv [2]; int length = strlen (filePath); argv [1] = new char (length +1); strncpy (argv [1], filePath, length); after this I have in argv [1] the desired chars but also some other undefined chars! The second and the third methods use two library functions strcpy() and memcpy() respectively to copy the content of const char* to char* variable. Pointers point to other parts of memory which must, in of themselves, exist. You will have to store the characters, not just a pointer to them. Doing double the work is not necessarily bad but given the optimal version is simple there's no reason not to use it.
