I need to write a string field in a structure data type to a file using
fprintf,fscanf.


I failed to use the below syntax. Please I need to not go outside
scanf,fprintf,printf .


/* Book name : The prodessional programmers guide to C
File name : E:\programs\tc\iti01\ch09\main\01setupm.c
Program discription: file setuping -up -Version 01-ver01-W
Logic :
1-open file for output
2-while more customers
2-1-input customers record
2-2-write customer record to file
3-write end of file record to file
4-close file
*/


#include <stdio.h>
#include <conio.h>
/*TV Rental file Set_up -Version 01
-Setting up a file containing sutomer information*/
struct customer_record /*Defining a csutomer record*/
{
int customer_no;
char customer_name[20];
int no_of_weeks;
char tv_type;


};


main ()
{
/*-------1-open file for output*/
struct customer_record customer;
FILE *fp_setup;
if ((fp_setup=fopen("setup.txt","w")) == NULL)
{
printf("\nCan not open file 'setup.txt' for writing \n");
printf("Program is termainted");
exit(0);

}


clrscr();

/*-------2-while more customers----------separate function-------*/
do {
/*-------2-1-input customers record------separate function-------*/
customer_input(&customer);


/*-------2-2-write customer record to file*/
fprintf(fp_setup,"%4d%2d%c\n",customer);


} while (another_customer()=='y');


/*-------3-write end of file record to file */
fprintf(fp_setup,"%4d%2d%c\n",9999,99,' ');
/*-------4-close file*/
fclose(fp_setup);
return 0;


}


customer_input(cust)
/*---------------------*/
struct customer_record *cust;
{
int i=0;
printf("\nEnter customer number :");
scanf("%4d",&(*cust).customer_no);
printf("\nEnter customer name :");
scanf("\n");
for (i=0;(*cust).customer_name[i] != '\n' || (i<=20);i++)
scanf("%c",&(*cust).customer_name[i]);
printf("\nEnter number of weeks rent due :");
scanf("%2d",&(*cust).no_of_weeks);
printf("Enter type of rental -c for colors TV");
printf("\n -b for black and white TV");
printf("\n -v for video");
printf("\n -o for other : ");
scanf("\n");
scanf("%c",&(*cust).tv_type);
return 0;


}


another_customer()
/*----------------*/
{
char another;
printf("\nAnother new_screen_customer for input (y or n) : ");
scanf("\n");
scanf("%c",&another);
return (another);


}
