Question

Q.1. Create a C++ class template called ArrayCalc, to perform a series of mathematical operations on an array. These mathematical operations are calculating the minimum, maximum, sum and average values of the array. The ArrayCalc class template accepts one type parameter, which can be defined as: template <class T>. This allows ArrayCalc to carry out operations for different array data types. ArrayCalc has the following public methods, described here in pseudo code: i. void FindMin(inArrayData[], inArraySize, SoutMinVal); (This function accepts the input array data and size and returns the calculated min value as an output argument.) ii. void FindMax (inArrayData[], inArraySize, SoutMaxVal); (This function accepts the input array data and size and returns the calculated max value as an output argument.) iii. void CalcSum (inArrayData[], inArraySize, SoutSumval); (This function accepts the input array data and size and returns the calculated sum value of the array content as an output argument.) iv. void CalcAvg (inArrayData[], inArraySize, SoutAvgVal) ; (This function accepts the input array data and size and returns the calculated average value of the array content as an output argument.) Note: Write a complete C++ class template based on the requirements above. Write a driver program (i.e. main() function) to test this class.

#include<bits/stdc++.h>
using namespace std;

template<class T>
class ArrayCalc {
public:

     void FindMin(T inArrayData[],int inArraySize, T &outMinVal );
     void FindMax(T inArrayData[],int inArraySize, T &outMaxVal );
     void CalcSum(T inArrayData[],int inArraySize, T &outSumVal );
     void CalcAvg(T inArrayData[],int inArraySize, T &outAvgVal );
};
template <class T>
void ArrayCalc<T>::FindMin(T inArrayData[],int inArraySize, T &outMinVal )
{

    for(int i=0;i<inArraySize;i++)
    {
        if(inArrayData[i]<outMinVal)
        {
            outMinVal=inArrayData[i];
        }
    }
}

template <class T>
void ArrayCalc<T>::FindMax(T inArrayData[],int inArraySize, T &outMaxVal )
{

    for(int i=0;i<inArraySize;i++)
    {
        if(inArrayData[i]>outMaxVal)
        {
            outMaxVal=inArrayData[i];
        }
    }
}

template <class T>
void ArrayCalc<T>::CalcSum(T inArrayData[],int inArraySize, T &outSumVal )
{

    for(int i=0;i<inArraySize;i++)
    {
        outSumVal+=inArrayData[i];
    }
}

template <class T>
void ArrayCalc<T>::CalcAvg(T inArrayData[],int inArraySize, T &outAvgVal )
{

    for(int i=0;i<inArraySize;i++)
    {
        outAvgVal+=inArrayData[i];
    }
    outAvgVal=outAvgVal/inArraySize;
}

int main()
{
    int n; //size of array should always in int
    cin>>n;
    int ar[n];
    for(int i=0;i<n;i++)
        cin>>ar[i];
    int outMinVal=INT_MAX;
    int outMaxVal=INT_MIN;
    int outAvgVal=1;
    int outSumVal=0;
    ArrayCalc<int>a;
    a.FindMin(ar,n,outMinVal);
    a.FindMax(ar,n,outMaxVal);
    a.CalcSum(ar,n,outSumVal);
    a.CalcAvg(ar,n,outAvgVal);

    cout<<"The Minimum value is "<<outMinVal<<endl;
    cout<<"The Maximum value is "<<outMaxVal<<endl;
    cout<<"The Average value is "<<outAvgVal<<endl;
    cout<<"Total Sum is "<<outSumVal<<endl;
    return 0;
}

//Output for int type

//output for float type
