Thread: Problem writing to file

I wrote this code but it does'nt write to the file all the things the user inputs. The user inputs 2 different dates and the name of the car and for how much it was purchased for but none of that show up in the file. What could be the problem with it?

Code:

#include <stdio.h>

#define s 20

#define sof 10

typedef struct { 
	int day;
	int month;
	int year;
} Date;

typedef struct {
	float cost;
} Price;

typedef struct {
	char make[s];
	Date purchaseDate;
	Date manufactureDate;
	Price purchasePrice;
} Car;

int displaycar (Car car[]);

int main()
{
	
	Car car[sof];
	
	int i,j;
	FILE *outp;
	for(i=0; i<sof; i++)
	{
			printf("Please Enter the name of the car: ");
			scanf("%s",&car[i].make);

                                        printf(" Please enter the day of purchase: ");
                                        scanf("%d", &car[i].purchaseDate.day);

                                        printf(" Please enter the month of purchase: ");
                                        scanf("%d", &car[i].purchaseDate.month);

                                        printf(" Please enter the year of purchase: ");
                                        scanf("%d", &car[i].purchaseDate.year);
		
                                        printf(" Please enter the day of manufacture: ");
                                        scanf("%d", &car[i].manufactureDate.day);

                                        printf(" Please enter the month of manufacture: ");
                                        scanf("%d", &car[i].manufactureDate.month);

                                        printf(" Please enter the year of manufacture: ");
                                        scanf("%d", &car[i].manufactureDate.year);
		
                                       printf(" Please enter the price the car was bought for: ");
                                       scanf("%f", &car[i].purchasePrice.cost);
                                       }
outp =fopen("c:\\Car.txt", "w");
for(j=0; j<=sof; j++)
{
	fprintf(outp,"%c\n", car[j]);
}

displaycar(car);

return 0;
}

int displaycar (Car car[])

{
	printf(" The name of the car is %s \n", car->make);
	
printf(" The car was purchased on the %d of the %d of the year %d\n", (car->purchaseDate).day, (car->purchaseDate).month, (car->purchaseDate).year);

printf(" The car was manufactured on the %d of the %d month of the year %d \n",(car->manufactureDate).day, (car->manufactureDate).month, (car->manufactureDate).year);

printf(" The car was bought for %lf \n",(car->purchasePrice).cost);

return 0;
}

Hello I made the changes suggested and this time instead of the program writing 1 character to file it crashed why is it taht when I used strings it crashed and why will it not put tyhe entire thing on the file.

Code:

outp =fopen("c:\\Car.txt", "w");
for(j=0; j<=sof; j++)
{
	fprintf(outp,"%s\n", car[j]);
}
fclose(outp);

because car is a structure that contains several objects. You can't pass the entire structure to fprintf() and expect that function to decide which of the structure members to use. Garbage in -- garbage out.

Code:

fprintf(outp,"%s\n", car[j].make);

I made the changes but the output is still not what i want it to be

car
car
car

is the output but it's meant to copy the entire array into the file. Is there any way of doing it because i'am on the verge of giving up

what have you done so far? post most recent code. If you want to make the file readable by other text editors such as notepad.exe then you have to program it to write each member of the structure similar to the way we posted how to save the car[j].make. From this example it should not be difficult to write out the rest of the structure in similar format.

Code:

// save make
fprintf(outp,"%s\n", car[j].make);
// save purchase date in mm/dd/yyyy format
fprintf(outp,"%02d/%02d/%04d\n", purchaseDate.month,
              purchaseDate.day,
              purchaseDate.year);
