[英]how to take user input, do math to that input, and store the results in an array? in C++
I feel like there is a better way to do this getOvertones function with an array.我觉得有更好的方法可以用数组来完成这个 getOvertones function 。 Clearly the code takes an input (hz) and then gets the overtone frequencies.
显然,代码采用输入 (hz),然后获取泛音频率。 I know there must be a more proficient way to do this.
我知道必须有更熟练的方法来做到这一点。 Any help is greatly appreciated as I am trying to teach myself.
非常感谢任何帮助,因为我正在努力自学。
double getOvertones()
{
double root;
std::cout << "enter frequency" << '\n';
std::cin >> root;
double fundamental = root;
double second = root * 2.00;
double third = root * 3.00;
double fourth = root * 4.00;
double fifth = root * 5.00;
std::cout << fundamental << '\n'
<< second << '\n'
<< third << '\n'
<< fourth << '\n'
<< fifth << '\n';
return fundamental;
};
I was trying things like:我正在尝试这样的事情:
double frequency;
cin >> frequency;
double overtones[5];
for i in overtones...
I'm not sure a this point how to fill an array with math results basically.我不确定这一点如何基本上用数学结果填充数组。
double getOvertones()
{
double root;
double root2;
std::cout << "enter frequency in hz" << '\n';
std::cin >> root;
for (double i = 1; i < 6; i++)
{
root2 = root * i;
std::cout << root2 << '\n';
}
return root2;
};
