Doesn't compile

[ddaniel10]

My code doesn't compile, I'm pretty sure the error is in the *inputscores function. Can someone tell me what I did wrong?

  #include <iostream>
#include <string>
using namespace std;

struct Student
{
	string name;	// name of student
	int ID;		// student ID
	int* tests;		// Pointer to an array of test scores 
	double average;		// Average test score
	char grade;		// Grade
};

int numStudents();
int Tests();
string inputName();
int inputID();
int *inputScores(int);
double calcAverage(int*, int);
char calcGrade(double);
void display(Student*, int);

int main()
{
	Student *studentList;
	int size = numStudents();
	studentList = new Student[size];

	//Holds number of tests
	int numTests = Tests();

	for (int count = 0; count < size; count++)\
	{
		studentList[count].name = inputName();
		studentList[count].ID = inputID();
		studentList[count].tests = inputScores(numTests);
		studentList[count].average = calcAverage(studentList[count].tests, numTests);
		studentList[count].grade = calcGrade(studentList[count].average);
	}

	display(studentList, size);

	delete[] studentList;

	system("pause");
	return 0;

}

int numStudents()
{
	int students;
	cout << "How many students are there?" << endl;
	cin >> students;

	return students;
}

int tests()
{
	int tests;
	cout << "How many tests will there be?" << endl;
	cin >> tests;

	return tests;
}

string inputName()
{
	string name;
	cout << "How many tests will there be?" << endl;
	cin >> name;

	return name;
}

int inputID()
{
	int ID;
	cout << "What is the student's ID number?" << endl;
	cin >> ID;

	return ID;
}

int *intputScores(int numTests)
{
	int *scores;
	scores = new int[numTests];

	cout << "Enter the test scores for the student. Press Enter after each score." << endl;

	for (int count = 0; count < numTests; count++)
	{
		cout << "Score " << (count + 1) << ": ";
		cin >> scores[count];
	}

	return scores;
}

double calcAverage(int *testScores, int numTests)
{
	int total = 0;
	double average;
	
	for (int count = 0; count < numTests; count++)
	{
		total += testScores[count];
	}

	average = total / numTests;
	return average;

} 

char calcGrade(double average) {

	char letterGrade;

	if (average > 90 && average <= 100)
		letterGrade = 'A';
	else if (average > 80 && average <= 90)
		letterGrade = 'B';
	else if (average > 70 && average <= 80)
		letterGrade = 'C';
	else if (average > 60 && average <= 70)
		letterGrade = 'D';
	else if (average >= 0 && average <= 60)
		letterGrade = 'F';
	else {
		cout << "Logic error." << endl;
		// system("pause");
		exit(EXIT_FAILURE);
	}

	return letterGrade;
}

void display(Student *studentList, int size)
{
	for (int count = 0; count < size; count++)
		cout << studentList[count].name << " " << studentList[count].ID << " "
		<< studentList[count].average << " " << studentList[count].grade << endl;

	return;
}

what error do you get ?

Typo on line 86 in the function name
intputScores vs.
inputScores

Fixed the typo, thank you. but now I get this error.

C++ is case sensitive, you declare int Tests(); on line 15, but define int tests() starting on line 59.

If you get similar errors, try looking for inconsistencies or typos like this.
