变量数组值取决于增加的行号 [英] variable array value depending on increasing row number
问题描述
我正在处理的我的程序的简短描述：我输入一个数字 n 这意味着行数。 a b 变量表示矩形的尺寸 - 其第二个输入。然后，最重要的部分。我有一个人站在这个矩形上，起始位置 x y ，起始方向 s 。 x y 在范围内，您可以在代码中看到。方向是S，J，V，Z（N，S，E，W）。所以这个输入在第三行，它由3个参数组成： x y s 。你可以在我的代码中看到，如果我输入S，我的 y 值增加+1，J减少 y 值为-1，等等。
在我的代码的末尾是一个for循环，它一次输出所有的输入，因为我不想立即输出
2
5 8 // ab尺寸Uloha 1 1）：
4 5 S // xys（S表示y + 1）Uloha 2：
2 3 Z // xys（Z表示x-1） 输出：
1 3 Z //这里应该是 4 6 S p>
1 3 Z
得到两行输出，但是 xys 的值只是第二行的最终值，因此它不会在逻辑上记住每个任务。每次输入新行时， x y s 的最后一个输入值会更改。此外，如果 x y 低于0或高于<$，则有一个if条件不起作用c $ c> a 或 b ，它应该打印 SPADOL 。
你觉得什么建议？ Btw，我只是一个初学者在C + +。谢谢。

A short description of my program that I am working on: I input a number n which means number of rows. a b variables stands for dimensions of rectangle - its second input. Then, most important part. I have a person which is standing on this rectangle and has a starting position x y and starting direction s. x y are in range as you can see in the code. Directions are S,J,V,Z (N,S,E,W). So this input is in 3rd row and it consists of 3 parameters: x y s. As you can see in my code, if I input S, my y value increases by +1, J decreases y value by -1, etc..
At the end of my code is a for loop, which outputs all inputs at once, because I don not want it output right away, after each input.
My problem is, I input:
2 // number of tasks or rows
5 8 // a b dimensions
Uloha 1 (Task 1):
4 5 S // x y s (S means y+1)
Uloha 2:
2 3 Z // x y s (Z means x-1)
Output:
1 3 Z // here should be 4 6 S
1 3 Z
I press enter, and I get two rows of output but the values of x y s are only final values of the second row, so it doesnt remember each task, logically. The last input value of x y s changes every time I input new row. And also, there is a if condition which is not working too, when x y goes under 0 or above a or b, it should print SPADOL.
What do you think, any suggestions? Btw, Im just a beginner in C++. Thank you.

Put brackets when you use the or condition (a&&b) | (c&&d).
if(!(((x>=0)&&(x<=a)) | ((y>=0)&&(y<=b)))){
This code is working for me. You can use the c++ vector to store the values and print them at the end.
