这是一个用编程实现的一个数值积分的c语言代码，只要输入积分函数和积分的上下界，就可以快速积分结果。速度非常快,很不错的，大家可以拿去做成应用软件！-This is a program used to achieve a numerical integration of the c language code, as long as the input function and integral integral upper and lower bounds can be the result of rapid integration. Very fast, very good, we can take into application software!
