c++ - 打印 ASCII 艺术钻石

Question

这是我在学校编程类(class)的作业题，我有点迷路了，所以请帮忙。这是问题:

Write an application program that prints a diamond of asterisks (*) on the screen. The number of lines in the diamond is given by the user. As an example, if the user requested a diamond with 7 lines, the following would be displayed.

这是我目前所拥有的:

{
  int nlines;
  int nsp;
  cout << "enter the number of lines (must be more then one)" << endl;
  cin >> nlines;
  while((nlines)<=0)
  {
    cout << "enter the number of lines (must be more then one)" << endl;
    cin >> nlines;
  }
  nsp=(nlines - 1)/2;
  for(int currspace = 1; currspace <= nsp; currspace++)
  {
    cout << " ";
  }
  cout << "*" << endl;
  for( int currentline = 0; currentline < nlines; currentline++)
  {
    for( int currentaster = 0; currentaster <= currentline; currentaster++)
      cout << "*";
    cout << endl;
  }
  return 0;

我不会尝试给出完整的答案，因为它是家庭作业，但我的直接建议是尝试将任务分解为一些子任务，每个子任务都比较简单。例如，我会从一个小函数开始，它只打印出 一 行指定长度的星号和指定的理由。从事情的表面上看，您可能可以很容易地处理这些事情，并且有了它，剩下的就更简单了。
