1.　　本演示程序中演示的是多项式,其中多项式的项系数为浮点形,而x的指数为整形.多项式的构造过程中以输入的项系数和x的指数均为零为结束条件.在允许的范围内对程序作了出错处理.-1. The demonstration process is a demonstration of the polynomial, which polynomial coefficients to float shape, x and the index for plastic surgery. Polynomial tectonic process to input coefficient and x is the index to end all conditions. in within the scope allowed by the procedures of the error.
