根据所给的点的坐标算出最拟合曲线的公式，并根据原来的x值算出新的y值。并将数据储存到一个data文件-A C++ programme finds the best-fitted straight line to the x and y values, and then writes the original x, y values and the new y values on the line (for each x) to a data file. X: 1.0000 2.0000

问题描述：一个算术表达式是由操作数(operand)、运算符(operator)和界限符(delimiter)组成的。假设操作数是正整数，运算符只含加减乘除等四种运算符，界限符有左右括号和表达式起始、结束符“#”，如：#（7+15）*（23-28/4）#。引入表达式起始、结束符是为了方便。编程利用“算符优先法”求算术表达式的值。 基本要求：从键盘读入一个合法的算术表达式，输出正确的结果；显示输入序列和栈的变化过程，操作数类型扩充到实数。 -Problem Descr iption: An
