6-8 reading and writing of structured files 1

Student type ：ST The types of are defined as follows ：

typedef struct student{ char name[10],id[10]; int gender; int age; double scored; } ST; Write function , Read several strings from the specified file , Each line of string is a student's information （ full name , Student number , Gender , Age , fraction ） String representation of , The data room is marked with Space Separate , Store students' information in a structure , And make use of output() Function to the specified file .

Function interface definition ：

void fun(FILE *fin,FILE *fout);

among  fin  and  fout  All parameters passed in by the user . The former is a readable file that has been opened normally , The latter is a normally opened writable file .

Sample referee test procedure ：

 Here is an example of a function being called for testing . for example ：
#include <stdio.h>
#include <stdlib.h>
typedef struct student{
    char name[10],id[10];
    int gender;
    int age;
    double scored;
} ST;
void output(ST *d,FILE *fout){// The test program , Output to file call this function to complete 
    if(d==NULL) {printf("null\n");return;}
    fprintf(fout,"%s,%s,%d,%d,%4.2f\n",d->name,d->id,d->gender,d->age,d->scored);
}

void fun(FILE *fin,FILE *fout);//<-- Functions to be completed （ Including read in string , Convert to the corresponding structure , And use function （output（）） Output to the specified file , Input and output files do not need to be considered

sample input ：

Read from fixed file ： The contents of the document ：

aaa   123   0 18 88.88
bbb 456   1 19  99.99
ccc 789 1 18 66.66
ddd   356   0 18  67.89

sample output ：

Output to the specified file , The contents of the document ：

aaa,123,0,18,88.88
bbb,456,1,19,99.99
ccc,789,1,18,66.66
ddd,356,0,18,67.89

void fun(FILE *fin,FILE *fout)
{
    for(ST s;fscanf(fin,"%s%s%d%d%lf",s.name,s.id,&s.gender,&s.age,&s.scored)!=EOF;output(&s,fout)); 
    // Be careful ,id Use %s, Because of prevention 0XX The situation of , This condition is not available %d Read
