问题:

解答:

#include <iostream>
using namespace std;#define SIZE 10double* fill_array(double* begin, double* end)
{for (begin; begin < end; begin++){cout << "请输入值:";cin >> *begin;if (cin.fail()){cout << "非法数字,结束输入!" << endl;break;}}return begin;
}void show_array(double* arr, double* end)
{double* n = arr;cout << "数组信息为:";for (n; n < end; n++){cout << *n << "  ";}cout << endl;
}void revalue(double r, double* arr, double* end)
{double* n = arr;for (n; n < end; n++){(*n) *= r;}
}int main()
{double array[SIZE];double* begin = &array[0];double* end = &array[SIZE];double *index=fill_array(begin, end);show_array(array, index);revalue(2, array, index);show_array(array, index);return 0;
}

运行结果:

考查点:

• 数组和指针
