Question

My code is giving me garbage out...I want them to caculate the credits by quality points but its giving me garbage out.. I think my format is wrong not sure heres my code:


#include <iostream>
#include <iomanip>
#include <string>
//Function prototypes
using namespace std;
void printGpa(string, string, double, double);

//**here should I instead of listing separte just use one caculate gpa varible
//for getting my gpa caculated?

double caculateGpa1(int, double);
double caculateGpa2(int, double);



int main ( )
{
//Declare varaibles
string n1;
string n2;
int credits1;
int credits2;
double points1;
double points2;
double grade1;
double grade2;

//Intro
cout << " Students GPA Caculator" << endl;
cout << endl << endl;

// String of students last name
cout << " Please Enter The First Students Last Name ";
cin >> n1;
cout << " Please Enter The Second Students Last Name ";
cin >> n2;

//Input of Data for Quality Points
cout << " Please Enter " << n1 << " Quality Points ";
cin >> points1;
cout << " Please Enter " << n2 << " Quality Points ";
cin >> points2;
//Input of Total Credits Earned
cout << " Please Enter " << n1 << " Total Credits Earned ";
cin >> credits1;
cout << " Please Enter " << n2 << " Total Credits Earned ";
cin >> credits2;

cout << endl << endl;

//Call to functions Caculating GPA
double caculateGpa1(grade1);
double caculateGpa2(grade2);

//Call to funtions printname, gpa1, gpa2
printGpa(n1, n2, grade1, grade2);


system("PAUSE");
return 0;




// Vaule-returning function printname function
}
void printGpa(string n1, string n1, double grade1, double grade2)
{
cout << fixed << showpoint;
cout << setprecision(2);

cout << " " << n1 <<" GPA is " << grade1 << endl;
cout << " " << n2 <<" GPA is " << grade2 << endl << endl;

}
//Value-returning function definition
double caculateGpa1(int credits1, double points1)
{

double grade1;
gpa1 = points1 / credits1;
return grade1;
}
double caculateGpa2(int credits2, double points2)
{

double grade2;
gpa1 = points2 / credits2;
return grade2;
}
