现在如果把csv文件换成输出成txt文件，怎样修改代码才能顺利读取文件

Question

这张图片的内容是csv文件

读取并存储各个元素以用以计算的代码如下

include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include<iostream>
#include<math.h>
#include<stdlib.h>
#include<fstream>
#include<sstream>
#include <complex>
#include <string.h>


using namespace std;
 
typedef struct record
{
    int serial_number;
    char code_name[128];
    char name[128];
    int number;
    char material[128];
    float single_weight;
    float total_weight;
    char material_code[128];
    char remark[128];
}record;
 
#define MAX_LINE 1024
static record records_[MAX_LINE];
 
int main()
{
    int ret,i,count;
    FILE* f = fopen("D://zhao//0725//32处理前.csv", "rb");        
    if(!f)
        cout<<"fail to read file"<<'\n';
    //cin.get();


    for (i = 0; i < MAX_LINE; i++)
    {
        ret = fscanf(f, "%d,%[^,],%[^,],%d,%[^,],%f,%f,%[^,],%[^\r]", &records_[i].serial_number, 
            records_[i].code_name, records_[i].name, &records_[i].number, records_[i].material,
            &records_[i].single_weight, &records_[i].total_weight, records_[i].material_code, records_[i].remark);//按行读取
        if(records_[i].serial_number == 0)
            break;    
    }
    fclose(f);
    count = i;
    printf("csv line count %d\n", count);    
    for (i = 0; i < count; i++)
    {
        cout<<"i="<<i<<'\t'<<records_[i].serial_number<<'\t'<<records_[i].remark<<'\n';
    } 





    ofstream of("D://zhao//0725//处理后//11.txt");
    //of.setf(ios::fixed);
    if(!of)
    {
        cout<<"不能打开目的文件\n";
        cin.get();
    }
    
    of<<"序号"<<'\t'<<"物料码"<<'\t'<<"名称"<<'\t'<<"代号"<<'\t'<<"材料"<<'\t'<<"数量"<<'\t'<<"         "<<'\t'<<"备注"<<'\n';
    for(i>0;i--;)//nnp:particle name//
    {


        of<<records_[i].serial_number<<'\t'<<records_[i].material_code<<'\t'<<records_[i].name<<'\t'<<records_[i].code_name<<'\t'<<records_[i].material<<'\t'<<records_[i].number<<'\t'<<"         "<<'\t'<<records_[i].remark<<'\n';
        
    }

    cout<<"Complete the calcula"<<'\n';
    cin.get();
    return 0;
}

现在如果把csv文件换成输出成txt文件，内容还是一样，怎样修改代码才能顺利读取文件。

csv文件如下：

txt文件如下：

相关csv和txt文件可以从如下链接下载，劳烦各位帮忙测试一下。提取码1234。
