file input and output

[steve1_rm]

Hello

C problem
I am having problems saving a structure to a text file. My structure is below.

What is the best way to save this to a file and open it from a file and display it on the screen. I have tried several ways but can't get it to work propertly.

I have tried using fread and fwrite, but having problems with it.

This is what l have done so far. It is bits of code that does not work

//Structure that Holds details for all the customers 
struct freight{ 
char name[20]; 
char address[40]; 
char goods[30]; 
int quantity; 
char destination[30]; 
} customerDetails[20]; 



//Code for opening the file
if((fileCustomers = fopen(fileName, "wb")) == NULL) 
printf("\nCannot save this record"); 

//Code for writing to the file
for(i=0; i<=recordNumber; i++){ 
if(fwrite(&customerDetails[i], sizeof(struct freight),1,fileCustomers) != 1){ 
printf("\nError saving customer records"); 
exit(1); 
} 
} 
fclose(fileCustomers);

//code for opeing the file
if((fileCustomers = fopen(fileName, "rb")) == NULL){ 
printf("\nCannot not find customer records on disk"); 
printf("\nOr file may not have been created yet"); 
} 

//Code for reading from the file.
for(i=0; i<=2; i++){ 
if(fread(&customerDetails[i],sizeof(struct freight),1,fileCustomers) != 1){ 
printf("\nError opening customer records"); 
exit(1); 
} 
} 
fclose(fileCustomers);
