declaraton & args

[quant]

hello everybody,
When I do that it say to me what "data" undeclarated.

void create(){
add.time->(&data);
}
int main(int argc , char *argv[]){
argv[1] = (char *)data;
}

If declarate "data" in global, then I take null into "add.time->(&data);"
I want give data from args to void create().
Please, help me in that mistake.

What do you mean anyway?

int main(int argc , char *argv[]){
argv[1] = (char *)data;
}

argv[1] is read only.

resolved.
data = argv[1];
