fscanf读取文件出问题，请大家帮忙

kesin

自己写的处理数据文件的小程序，查错查到最后发现fscanf根本不工作，实在找不出问题所在，把程序和数据文件都贴出来，肯请大家帮忙解决！
编译环境：devcpp4.9.9.2

//代码文件：main.cpp
#include <iostream>;
#include <stdlib.h>;
using namespace std;

int main(int argc, char *argv[])
{
    void merge_zone_fcs(char *);
    merge_zone_fcs(argv[1]);
   
    system("AUSE";
    return 0;
}

void merge_zone_fcs(char *well)

    FILE* fp_in1, *fp_in2, *fp_out;
        char *fn_in1=new char[20];
        char *fn_in2=new char[20];

        strcpy(fn_out, well);

    if((fp_in1=fopen(fn_in1,"r")==NULL)
    {
                printf("Cannot Open inputfile %s\n",fn_in1);
                exit(1);
    }

    if((fp_in1=fopen(fn_in2,"r")==NULL)
    {
                printf("Cannot Open inputfile %s\n",fn_in2);
                exit(1);
    }

    if((fp_out=fopen(fn_out,"w")==NULL)
    {
                printf("Cannot Open outputfile %s\n",fn_out);
                exit(1);
    }
    fscanf(fp_in2,"%s%lf",fcs_name,&f_top);
    cout<<fcs_name<<endl<<f_top<<endl;
        fscanf(fp_in1, "%lf%d", &z_top1, &zonecode1);
        cout<<z_top1<<"\t"<<zonecode1<<endl;
       
        fprintf(fp_out,"%12.3lf  -999  -999\n",z_top1);
        fclose(fp_in1);
        fclose(fp_in2);
        fclose(fp_out);
        return;

if((fp_in1=fopen(fn_in2,"r")==NULL)
   {
printf("Cannot Open inputfile %s\n",fn_in2);
exit(1);
   }

应该改成

if((fp_in2=fopen(fn_in2,"r")==NULL)
   {
printf("Cannot Open inputfile %s\n",fn_in2);
exit(1);
   }

这几天活忙，脑子太乱了！眼睛也不好使了！还总以为机器跟自己过不去！
