Something about p2p clients code

See more:

C

Now I'm trying to make a sofeware about online video on demand,use p2p to solve network question.
The following is an error & i can't find the way...
PS: it's seems like a litter longer... forgive me...

int Command() //get the command
{
	char key[256],temp[256];
	int i,j,result;
	char *command[6]={"connect","play","pause","stop","quit","?"};
	char parameter[256];
	printf("please input command................\n");
	while(1)
	{
		memset(key,0,256);
		memset(temp,0,256);
		memset(parameter,0,256);
		int flag=0;
		printf("%s>>",strHostName); //show the command symbol
		gets(temp);
		j=0;  //remove the excess space 
		for(i=0;i<strlen(temp);i++)>
		{

		}
		key[j+1]='\0';
		i=strcspn(key," ");

int Connect(LPSTR parameter)
{
	int i,j,k,len=strlen(parameter);
	char temp[10];
//////////////////////////////////////////////////parameter/////////////////////////////////////////
	if(!strlen(parameter))
		return 1;  //no parameter
	k=strcspn(parameter," ");
	parameter[k]=5;
    i=0;j=0;
	while(parameter[i]!=5)
	{
		sIP[j]=parameter[i];
		i++;j++;
	}
	sIP[j]='\0';

	k=strcspn(parameter," ");
	if(k==len)

	parameter[k]=5;
    i++;j=0;
	while(parameter[i]!=5)
	{

	}
	strPassWord[j]='\0';

	while(parameter[i]!='\0')
	{
		temp[j]=parameter[i];
		i++;j++;
	}
	temp[j]='\0';
	Port=atoi(temp);

Then open clients.exe,no matter what words,the answer always be"parameters are not enought¶meters are more "
I have no idea about it...hope someone to save me unless my god..

Edit: Changed tags to C as there's no C++ in there
