Write a program that calculates the average for 5 marks entered by the users using any type of c++ loops

Answer 1

#include <iostream>
using namespace std;

int main() {
double scores=0;
for(double d =0; d<6; d++)
{
cout << "enter score " << d << endl;
cin >> scores;

scores+=scores;
}
cout << "avr: "<<scores /5.0<<endl;
return 0;
}

Answer 2

//A bit long but works fine:

#include<iostream>
#include<vector>

class Mark
{
private:
int m_mark;

public:
void setMark(int mark)
{
m_mark = mark;
}

int getMark()
{
return m_mark;
}
};

void setMarks(int number,std::vector<Mark> &marksVector)
{
for (int counter = 0; counter < number; counter++)
{
std::cout << "Enter mark #" << counter + 1 << ": ";
int temp;
std::cin >> temp;

Mark pushThis;
pushThis.setMark(temp);
marksVector.push_back(pushThis);
}
}

void printAverage(std::vector<Mark> marksVector)
{
double numerator = 0;
double denominator=0;
double result;
for (int n = 0; n < marksVector.size(); n++)
{
++denominator;
numerator += marksVector.at(n).getMark();

}
result = numerator / denominator;
std::cout << "Average mark: " << result << std::endl;
}

int main()
{
std::vector<Mark> marksVector;

setMarks(5, marksVector);
printAverage(marksVector);
}
