Question

c++

Q.2. a) Create a C++ class template called MathCalc, to perform arithmetic operations between two numbers. These arithmetic operations are addition, subtraction, multiplication and division. The MathCalc class template accepts two type parameters, which can be defined as: template <class T, class U>. This allows MathCalc to carry out arithmetic operations between two different data types. MathCalc has the following public methods, described here in pseudocode: i. Ret Sum(augend, addend); Ret is the return value of the method. ii. Ret Subtract(subtrahend, minuend); Ret is the return value of the method. iii. Ret Multiply(multiplicand, multiplier); Ret is the return value of the method. iv. Ret Divide (dividend, divisor); Ret is the return value of the method. (If you don't know the meaning of those words, “augend” etc. just Google b) Create a simple driver program (i.e. main() function) to test the template class of part (a) above. Your driver program should instantiate an object of the MathCalc class specifying the actual data types of the T & U parameters. Figure Q3 illustrates a sample execution of the driver program. Enter two numbers: 10.5 12.5 Sum: 23 Subtract: 23 Multiply: -2 Divide: 131.25 Figure : Sample Program Execution

Answer 1

Hi There,

I have implemented the template class and respective functions.

I have assumed that class T and class U specify the datatypes of input variables of each function and type U is also the return type of each function.

Please comment below if you need more information or the code needs some changes.

Output:

Code:

#include <iostream>
using namespace std;
// type T and type U represent the datatype of both the variables.
// type U also represents the return type of the operation.
template <class T, class U>
class MathCalc
{
public:
U Sum(T augend, U addend)
{
return (U)(augend + addend); // sum = augend + addend
}

U Subtract(T subtrahend, U minuend)
{
return (U)(minuend - subtrahend);// diffrence = minuend - subtrahend
}

U Multiply(T multiplicand, U multiplier)
{
return (U)(multiplier * multiplicand);// product = multiplier * multiplicand
}

U Divide(T dividend, U divisor)
{
return (U)(dividend / divisor); // quotient = dividend / divisor
}
};

int main()
{
MathCalc<float, float> calc;
cout << "Enter two numbers of type float: ";
float f1, f2;

cin >> f1 >> f2;
try
{
cout << "Sum: " << calc.Sum(f1, f2) << endl;
cout << "Subtract: " << calc.Subtract(f1, f2) << endl;
cout << "Multiply: " << calc.Multiply(f1, f2) << endl;
cout << "Divide: " << calc.Divide(f1, f2) << endl;
}
catch (exception e)
{
cout << "Exception occured " << e.what() << endl;
}
  
int i1;
float f3;
cout << endl;
cout << "Enter two numbers of type integer and float: ";
MathCalc<int, float> calc2;
cin >> i1 >> f3;
try
{
cout << "Sum: " << calc2.Sum(i1, f3) << endl;
cout << "Subtract: " << calc2.Subtract(i1, f3) << endl;
cout << "Multiply: " << calc2.Multiply(i1, f3) << endl;
cout << "Divide: " << calc2.Divide(i1, f3) << endl;
}
catch (exception e)
{
cout << "Exception occured " << e.what() << endl;
}
  

return 0;
}
