looping, and inputing this info

IM TRYIING TO ADD THIS INFO TO MY PROGRAM BELOW. (this is just part of it).. HOW DO I DO THIS. IM NEW
i need to calcule for tuition..im not good on the , and loops, and using constants.....
its asks for name how many credits....etc. i need to make it print up on the output box as resident or non resident when they push r or n.

also it calculates how much money it cost per credit. for instance a resident student pays $200 per credit and cannot go above $3300 quater.

a non resident pays 400 a credit and cannot go above 5500

full time is 12 credits, and they cant go above 20 credits

so it needs to calculate their costs depending on how many credits they enter...

cout << "Enter the first name: ";
cin>> sFirst_name;
cin.ignore( 10000, '\n');

cout << "Enter the last name: ";
cin>> sLast_name;
cin.ignore( 10000, '\n');

cout << "Are you a resident? (Y/N) ";
cin>> Resident;
cin.ignore( 10000, '\n');

cout << "How many credits are you taking: ";
cin>> iCredits;
cin.ignore( 10000, '\n');
{
((iCredits <0) || (iCredits >20));
cout << "Error: done"<<endl;
}

{
if ((Resident == 'R') || (Resident == 'r'));

Res_Tuition = ((iCredits) * (Res_Cred));
cout << "tuition =" << Res_Tuition << endl;
}

if((Resident == 'N') || (Resident =='n'));

{
Non_Res_Tuition = ((iCredits) * (Non_Res_Cred));
cout << "tuition =" << Non_Res_Tuition << endl;
}

How about this:

Code:

#include <stdio.h>
#include <stdlib.h>
#include <string>
#include <iostream>

using namespace std;

// CPC = Cost Per Credit
const int CPC_NONRES = 400;
const int CPC_RES    = 200;

// max tuition
const int MAX_NONRES = 5500;
const int MAX_RES    = 3300;

template<class T> inline T MIN(T a, T b) { return (a < b) ? a : b; }
template<class T> inline T MAX(T a, T b) { return (a > b) ? a : b; }

// -----------------------------------------------------------------

string prompt(const string& s)
{
    string ans;

    while (true) {
        cout << s;
        cin >> ans;

        if (cin.bad() || cin.fail()) {
            cout << "** Input error. Try again." << endl << endl;
            continue;
        }
        if (!ans.length())
            break;

        cin.ignore(256, '\n');
        break;
    }

    return ans;
}

// -----------------------------------------------------------------

int main()
{
    string fname, lname, is_res, ncredits;
    int credits = 0;
    int cpc = CPC_NONRES;
    int max = MAX_NONRES;

    fname  = prompt("\nEnter your first name: ");
    lname  = prompt("Enter your last name: ");
    is_res = prompt("Are you a resident? (y/n): ");

    while (true) {
        ncredits = prompt("Number of credits: ");
        credits  = atoi(ncredits.c_str());

        if (credits > 0 && credits <= 20)
            break;

        cout << "** Invalid answer. Must be 1-20." << endl << endl;
    }

    if (is_res.at(0) == 'Y' || is_res.at(0) == 'y') {
        cpc = CPC_RES;
        max = MAX_RES;
    }

    char* total;
    char* cost;
    sprintf(cost,  "$%.2f", (float)cpc);
    sprintf(total, "$%.2f", (float)MIN<int>((credits * cpc), max));

    printf("\nTuition for %s %s:\n\n", fname.c_str(), lname.c_str());
    printf("   CREDITS   |   PER CREDIT   |      TOTAL\n");
    printf("-------------+----------------+-----------\n");
    printf("   %7d   |   %10s   |   %8s\n\n", credits, cost, total);

    return EXIT_SUCCESS;
}
