在Dijkstra的最短路径算法和其他算法中,检查边缘以查看它是否提供更好的节点路径被称为放松边缘.为什么叫做放松？

给定一个未知长度的字符串,如何使用cout输出它,以便整个字符串在控制台上显示为缩进的文本块？(这样即使字符串换行到新行,第二行也会有相同的缩进级别)

例:

cout << "This is a short string that isn't indented." << endl;
cout << /* Indenting Magic */ << "This is a very long string that will wrap to the next line because it is a very long string that will wrap to the next line..." << endl;

和期望的输出:

这是一个没有缩进的短字符串.

    This is a very long string that will
    wrap to the next line because it is a
    very long string that will wrap to the
    next line...
