else if (number >= 20 && number < 100) //2 digit numbers, > 20
	{

    int n =  (number / 10) % 10; // pulls off the tens place
    n -= 2;

		cout <<  greaterThan19[n] << endl;//lessThan20[secondNum]<< " dollar";

    int secNum = (number % 10 ); // saves the ones digit into secNum
    cout << secNum << endl;
        cout << lessThan20[secNum ] << endl;

You need to do what is done with n and secNum for the Hundreds and Thousands as well. I don't think it is a great idea to index into an array with the number you pulled from input but, it will work if you pay attention to how you setup your array. ie... notice I subtracted 2 from n.

There are multiple ways to do what you want.

Here are two: First with a function through recursion and then with just a loop

Through function with recursion:

void checkOption(int num)
{

    switch(num)
    {
        case 1:
        cout << "Option 1" << endl;
        break;
        case 2:
        cout << "Option 2" << endl;
        break;
        case 3:
        cout << "Option 3"  << endl;
        break;
        default:
        cout << "Illegal option: please input valid 1-3" << endl;
        int value;
        cin >> value;
        checkOption(value);
        break;

    }

}

int main()
{

checkOption(4);


    return 0;
}

Through loop:

int main()
{

//checkOption(4);

bool reloop = true;
int num = 0;
while(reloop)
{
    cout << "Enter option 1-3" << endl;
 cin >> num;

    switch(num)
    {
        case 1:
        cout << "Option 1" << endl;
        reloop = false;
        break;
        case 2:
        reloop = false;
        cout << "Option 2" << endl;
        break;
        case 3:
        reloop = false;
        cout << "Option 3"  << endl;
        break;
        default:
        cout << "Illegal option: please input valid 1-3" << endl;
        int value;

        break;

    }

}

    return 0;
}

dblpost

YOu use the insertion operator << just like you would for regular text. example

int age = 6;
cout << "At age " << age << "you are old as dirt" << endl;

prints: "At age 6 you are old as dirt"


It works the exact same way for a file.

Because you were using it on an integer. I couldn't even get your code to compile until I changed buf to a char. http://www.cplusplus...y/cstdio/fgets/ There is no int for that first parameter. I don't think it was your scanf that was causing the problem it was your fget. You don't actually need the scanf's.

int main()
{



int port1, port2;

char buf[100];
char secBuf[100];

char roomname1[100];
char roomname2[100];

printf("Please enter the name of chatroom 1 : ");

fgets(roomname1,100,stdin);

printf("Please enter the port of chatroom 1 : ");

fgets(buf,100,stdin);

// sscanf(buf,"%d",&port1);



// fflush(stdin);



printf("Please enter the name of chatroom 2 : ");

fgets(roomname2,100,stdin);
// string stophere;
// cin >> stophere;
cout << roomname2 << endl;
printf("Please enter the port of chatroom 2 : ");

fgets(secBuf,100,stdin);
cout << secBuf << endl;
// sscanf(secBuf,"%d",&port2);


return 0;
}
