C++ code - Calculate Average Scores Using Array

[thanglong]

Dear All,

Does anyone have C++ source code that calculates average scores using array? Please share!

Thank You!

double GetMean(double daArray[], int iSize) {
double dSum = daArray[0];
for (int i = 1; i < iSize; ++i) {
dSum += daArray;
}
return dSum/iSize;
}

int main()
{
double dValues[] =
{3.4, 4.8, 8.4, 9.6, 2.3, 9.6, 5.6, 9.6, 4.8, 2.2};
int iArraySize = 10;

std::cout << "Mean = "
<< GetMean(dValues, iArraySize) << std::endl;

return 0;
}

Thanks for the source code.

How do I allow users to input a list of numbers?

Simply create an array and copy user inputs to this array using cin.

here's what you can do

int main()
{
double *dValues = 0;
int iArraySize = 0;

cout << "please enter the size of the array";
cin >> iArraySize;

dValues = new double[iArraySize];

for(int i=0; i < iArraySize;i++)
{
cout << "Please enter the number:";
cin >> dValues;
cout << endl;

}

std::cout << "Mean = "
<< GetMean(dValues, iArraySize) << std::endl;

delete [] dValues;

return 0;
}
