In essence, will this code work? And before you say "Run it and see!", I just realized my cygwin didn't come with gcc and it's currently 40 minutes away from completing reinstallation. That being said:

char* words[1000];
for(int i = 0; i<1000; i++)
    words[i] = NULL;

char buffer[ 1024 ];

//omit code that places "ADD splash\0" into the buffer

if(strncmp (buffer, "ADD ", 4){
            char* temp = buffer + 4;
            printf("Adding: %s", temp);
            int i = 0;
            while(words[i] != NULL) i++;
            words[i] = temp;
}

I'm mostly uncertain about the line char* temp = buffer + 4, and also whether I can assign words[i] in the manner that I am. Am I going to get type errors when I eventually try to compile this in 40 minutes?

Also-- if this works, why don't I need to use malloc() on each element of words[]? Why can I say words[i] = temp, instead of needing to allocate memory for words[i] the length of temp?

Hello! Is it correct that following yields undefined behavior: void * something = NULL; char * buffer = new char[10]; something = buffer; buffer = NULL; delete [] something; // undefined?? Do I first need to cast something to void * ? Thank you! >>> More

I am trying to pass a value from C++ to TCL. As I cannot pass pointers without the use of some complicated modules, I was thinking of converting a vector to a char array and then passing this as a null terminated string (which is relatively easy). I have a vector as follows: 12, 32, 42, 84 which… >>> More
