我是一个初学者 很多东西我读到现在还是没有概念...
以下是我们老师派的一个问题...我去找过一些范例..但是我还是做不出来..
希望有人可以帮帮我..给点提示..或是弄个类似的给我参考都行...拜托各位帮帮忙..
Define a class for a type called Fraction. This class is used to represent a ratio of two integers. Include mutator functions that allow the user to set the numerator and the denominator. Also include a member function that returns the value of numerator / denominator as a double. Include an additional member function that outputs the value of the fraction reduced to lowest terms, e.g. instead of outputting 20/60 the method should output 1/3. This will require finding the greatest common divisor for the numerator and denominator, and then dividing both by that number. Embed your class in a test program.
int main()
{
// Some test fractions
Fraction f1, f2;
f1.setNumerator(4);
f1.setDenominator(2);
cout << f1.getDouble() << endl;
f1.outputReducedFraction();
cout << endl;
f2.setNumerator(20);
f2.setDenominator(60);
cout << f2.getDouble() << endl;
f2.outputReducedFraction();
cout << endl;
}
