朋友，我不知道 你 的这个程序的功能 是什么，但是我尽量帮你改到了 没有错误，可以运行，如果你还不满意 ，可以再联系我，我再帮你改了

#include<stdio.h>
#include<math.h>

double result;

void main()
{
double f1(double,double);
double f2(double,double);
double f3(double,double);
double f4(double,double);
double f5(double,double);
double integral(double,double,double(*fun)(double,double));
//double jifen(double,double,double(*fun)(double,double));
double m,n;
printf("please input the data of a&&b");
scanf("%lf,%lf",&m,&n);
printf("integral1's result=\n");
integral(m,n,f1);//jifen(m,n,f1);
printf("integral2's result=\n");
integral(m,n,f2);
printf("integral3's result=\n");
integral(m,n,f3);
printf("integral4's result=\n");
integral(m,n,f4);
printf("integral5's result=\n");
