Question

Given this code:

void group::build(int size, std::string *ips){
/*Build the LL after receiving the 
member list from bootstrap*/
head = new member("head");
member *temp1,*temp2;

temp1 = new member(ips[0].data());  // error here
    // ....
}

member::member(char *ip){
strcpy_s(this->ip_addr,sizeof(ip),ip);
this->next = NULL;
this->previous = NULL;
}

And a pointer to string defined as:

std::string *ips;

I want to initialize the array, ips with strings but when I try to get the char data from any array member I get the error:

cannot convert parameter from const char * to char *

Why?

Answer 1

Change line

member::member(char *ip)

to

member::member(const char *ip)

and, i’m not sure about your usage of strcpy_s
