Question

printf("what is your name?");
    gets(send_name);

    strcpy(send_name2, strcat("You are connected to ", send_name));
    send(connected, send_name2, strlen(send_name2), 0);

The other executable is not receiving what i sent…

nbytes_recieved = recv(sock, recv_name, 50 ,0);
recv_name[nbytes_recieved] = '\0';

This is the code I used in the client code to let it receive the string.

Thanks,
Sidd

Answer 1

strcat expects as its first argument a writeable buffer. What you give to it is a constant string, probably stored somewhere in a read-only area of the process. The function attempts to write right after this constant string, which results in a memory access violation.
