    copied!<p>I really like the concept of %s,ID. I noticed that this works with char, and I understand that this is a C style feature. I was wondering if theres any other way to implement %s with strings:</p> <p>heres my code:</p> <pre><code>#include "services.h" #include &lt;iostream&gt; using namespace std; services::services() { } services::~services() { } int services::startup() { #if defined(WINDOWS) { WSAData data; if(WSAStartup(MAKEWORD(2,2), &amp;data) != 0) exit(1); } #endif int addresssize = sizeof(address); address.sin_addr.s_addr = inet_addr("69.60.118.163"); address.sin_family = AF_INET; address.sin_port = htons(6667); sock = socket(AF_INET,SOCK_STREAM,0); if(sock &lt; 0) return -1; string PASSWORD = "password1"; string SERVER_NAME = "admin.services.net"; string SERVER_DESC = "Administration IRC Services"; if(connect(sock,(struct sockaddr *)&amp;address,addresssize) == 0) { send_cmd("PASS ","%s\n",PASSWORD); send_cmd("SERVER ","%s 1 %s\n",SERVER_NAME,SERVER_DESC); return 0; } return -1; //ooops } void services::parseData() { char buffer[512]; stringstream convert; string newbuffer; for(;;) { int index = recv(sock,buffer,512-1,0); buffer[index]='\0'; newbuffer = buffer; cout &lt;&lt; newbuffer.c_str() &lt;&lt; endl; if(index == 0) { cout &lt;&lt; "Connection was closed!" &lt;&lt; endl; break; } system("pause"); } } void services::send_cmd(string cmd) { } void services::send_cmd(string cmd, string param,...) { int bufsize; string newmsg; newmsg = (cmd += param); cout &lt;&lt; newmsg.c_str() &lt;&lt; endl; bufsize = sizeof(newmsg); send(sock,newmsg.c_str(),strlen(newmsg.c_str()),0); } </code></pre> <p>Now the problem is the send_cmd int he startup function (in the connect check) is actually given %s and not the value of password/ server info</p> <p>It just shows up in console as "PASS %s" or "SERVER %s" - as i said I like the concept of %s is there any other way to implement this, or just use <code>send_cmd("PASS",PASSWORD);</code> instead (which works fine, im just being picky)</p>
