How a program in c plus plus plus plus using function that returns the smallest of three floating-point numbers?

Answer 1

#include <iostream>

using std::cin;

using std::cout;

using std::endl;

double minimum(double arg1, double arg2, double arg3);

int main()

{

cout << "Enter first number: ";

double firstNumber = 0.0;

cin >> firstNumber;

cout >> "Enter second number: ";

double secondNumber = 0.0;

cin >> secondNumber;

cout << "Enter third number: ";

double thirdNumber = 0.0;

cin >> thirdNumber;

cout << "\nThe smallest number is " << minimum(firstNumber, secondNumber, thirdNumber) << endl;

return 0;

}

//All three arguments have to be different

double minimum(double arg1, double arg2, double arg3)

{

double min = arg1;

if (arg 1 > arg2)

{

min = arg2;

}

else if (arg1 > arg3)

{

min = arg3;

}

return min;

}
