I need help with a few minor things.

[HAssan]

The program is meant to write the entire contents of the array to the file called Car in the c directory but it's not working for some reason I was wondering if someone can help. I think the errors are very minor but I can'nt put my finger on it.

#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[sof]);

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[sof])
{
	
	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;
}

You should really check the return value of fopen() so that you know if the file was opened or not.

FILE *fp;
if((fp = fopen("what.txt","w") == NULL)){
  //error
}

[edit]
Ignore above post...

You are not sending any data to the file!
you ned to use fprintf()

fprintf(fp,"whatever");
