Basic File Reading in C

#include< stdio.h>
#include< stdlib.h>
int main()
{
int hesap;
char ad[30];
double bakiye;
FILE*fPtr;
fPtr=fopen("musteri.txt","r");
if(fPtr==NULL)
printf("Dosya Bozuk!!!");
else{
printf("%-10s%-13s%s\n","hesap","isim","bakiye");
fscanf(fPtr,"%d%s%lf",&hesap,ad,&bakiye);

while(!feof(fPtr)){
printf("%-10d%-13s%7.2f\n",hesap,ad,bakiye);
fscanf(fPtr,"%d%s%lf",&hesap,ad,&bakiye);
}
fclose(fPtr);
}
system("pause");
return 0;
}
    

Random Access File Reading in C

#include

struct musteriVerisi{
   int hesapNo;
   char soyisim[15];
   char isim[10];
   double bakiye;
   };
int main()
{
FILE*cfPtr;
struct musteriVerisi musteri={0,"","",0.0};
if((cfPtr=fopen("kredi.dat","r"))==NULL)
printf("Dosya acilamiyor\n");
else{
 printf("%-6s%-16s%-11s%10s\n","HspNo","Soyisim","Isim","Bakiye");
     while(!feof(cfPtr))
 {
 fread(&musteri,sizeof(struct musteriVerisi),1,cfPtr);
 
 if(musteri.hesapNo!=0)
 printf("%-6d%-16s%-11s%10.2f\n",musteri.hesapNo,
musteri.soyisim,musteri.isim,musteri.bakiye);        
     } 
     fclose(cfPtr);
 }
 getch();
