本实验需要先在一个象棋盘上建一个坐标轴，以输入各个棋子的位置坐标进行移动，但是对于棋子输入的初始坐标和移动后的坐标需要先判断坐标的位置是否合理，如果不合理就输出“输入错误”的提示。-This experiment you will need to build a coordinate axis in a chess board, to enter the coordinates of movement, but for the input of the initial coordinates and movement after the coordinates of the need to judge the position of the coordinate is reasonable, if not reasonable output "typos".
