嗨，我不是要求代码只是对如何尝试以下问题的基本理解。 [英] Hi, I'm not asking for the code just a basic understanding regarding how I should attempt the following question.

问题描述

编写一个程序，该程序使用for语句分别打印以下模式，一个在另一个之下。使用for循环生成模式。所有星号（*）都应该用cout<<<< '*';.

[提示：最后两种模式要求每一行以适当数量的空格开头。]



< b>我尝试了什么：



我没有尝试任何东西因为我不知道怎么做

Write a program that uses for statements to print the following patterns separately, one below the other. Use for loops to generate the patterns. All asterisks (*) should be printed by a single statement of the form cout << '*';.
[Hint: The last two patterns require that each line begin with an appropriate number of blanks.]

What I have tried:

I haven't tried anything since i don't know what do to

推荐答案

nv3的解决方案是正确的，你需要一个外部循环来控制内部循环。一点代码

The solution of nv3 is correct, you need an outer loop, which controls the inner loops. A bit of code

int first = 10;
for( int line = 0; line < 10; line++ ) {
  //inner loops
  for( int i = 0; i < first; i++ ) {
    cout << '*';
  }
  // loop control at end
  first--;
}
