Question

This piece of code gives me runtime exception: Unhandled exception at 0x00401189 in ControlFileChanges.exe: 0xC0000005: Access violation writing location 0xbaadf00d at the first strcpy command.

char** withStrings(string s1, string s2, string s3, string s4, string s5)
{
char** pipes;
pipes = (char**) malloc(sizeof(*pipes)*5);

strcpy(pipes[0],s1.c_str());
strcpy(pipes[1],s2.c_str());
strcpy(pipes[2],s3.c_str());
strcpy(pipes[3],s4.c_str());
strcpy(pipes[4],s5.c_str());

return pipes;
}

Any idea what the problem could be?
(This is a sample that I am using to use similar logic in my actual code).

Answer 1

You didn’t allocate memory to pipes[0], pipes[1], etc.

Since this is C++ and not C, did you consider using new instead of malloc ? Or maybe use a vector or strings ?
