Noob console programme question

[Redcode]

Hi all.

Could someone please tell me why nGrade comes out as 0 every time?

Its as if im not inputting the values into the dynamic arrays in int main.

Thank u

#include <iostream>
using namespace std;

void Calc(int a_anScores[], int a_anPerc[], int a_nTotal){
	
	for( int iii = 0; iii < a_nTotal; ++iii){
		a_anScores[iii] = (a_anScores[iii] * (a_anPerc[iii]/100));
	}
	int nGrade=0;
	for(int jjj =0; jjj<a_nTotal; jjj++){
		nGrade += a_anScores[jjj];
	}
		
    cout << "Your total grade is:" << nGrade;

	
}


int main (){
		
	 int nTotal;
	 cout << "How many assessments do you have in your course: " << endl << endl;
	 cin >> nTotal;
	 int* panScores = new int[nTotal];
	 int* panPerc = new int[nTotal];
	 int jjj = 1;

	 for (int iii = 0; iii < nTotal; ++iii){
		 
		cout << "Please enter grade of assessment " << jjj++ << " and then its percentage: " << endl << endl;
		 cin >> panScores[iii];
		 cin >> panPerc[iii];
		 }
	 
	 Calc(panScores, panPerc, nTotal);
	
	 system("pause");
}

It's happening at line 8. Integer division gives the quotient. The remainder is dropped.
For example: 8/5 = 1 . 3/5 = 0.
This quantity on line 8: a_anPerc[iii]/100 = 0 if a_anPerc[iii] is < 100. You will get better results using float or double type for panScores and panPerc instead of int.

Thanks! Changing those arrays to doubles as well as nGrade worked
