enum 枚举常量谁帮我讲一下我看书上的讲的不太详细
enum 枚举常量谁帮我讲一下我看书上的讲的不太详细 在这代码里没有理解透请老师和朋友们帮个忙 帮我解释下
程序代码：#include <iostream>
using namespace std;
enum ERR_CODE { SUCCESS, ERROR };
ERR_CODE Factor(int, int&, int&);
int main ()
{
int number, squared,cubed;
ERR_CODE result;
cout << "Enter a number (0 - 20):"
cin >> number;
result = Factor (number,squared,cubed);
if (result == SUCCESS)
{
cout << "number: " << number << endl;
cout << "squared: " << squared << endl;
cout << "cubed: " << cubed << endl;
}
else
cout << "Error encountered!! " << endl;
return 0;
}
ERR_CODE Factor(int, int&rSquared, int&rCubed)
{
if (n > 20)
return ERROR;
else
{
rSquared = n*n;
rCubed = n*n*n;
return SUCCESS;
}
}
