用C语言实现两个一元多项式的乘积，输入数据为两行，分别表示两个一元多项式，每个一元多项式以指数递增的顺序输入多项式各项的系数、指数。最后以指数递增的形式输出乘积。-C language with two unary polynomial of the product, the input data for the two lines, respectively, two unary polynomials, each one dollar increase in the order of polynomial to index all of the coefficients of the input polynomial, exponential. Finally, in the form of an exponential increase output of the product.
