Interesting Problem About Incrementing ++
Here is my code:

Code:
int startingPort = 200;
string tempPort;
stringstream out;
out<<startingPort;
tempPort = out.str();    //tempPort carries startingPort in string format

//convert tempPort to *char - currentPort going to be passed into getaddrinfo()
char currentPort[10];
strcpy(currentPort, tempPort.c_str());

while(startingPort <= 400)
{
                          //shows the first old value, does not show the incremented value
                          cout<<"******currentPort "<<currentPort<<endl;
       //move to the next port in the specified range
		startingPort++;

		//convert the incremented port to a string
		string tempPort;
		stringstream out;
		out<<startingPort;
		tempPort = out.str();
		char currentPort[10];
		strcpy(currentPort, tempPort.c_str());
                     
                          //works fine - incremented
		cout<<"TEST* currentPort "<<currentPort<<endl;
}

My program compiles, the problem is currentPort reset itself to 200 everytime a new loop starts...

This code is just example. Do you know why in every loop, the value reset itself?
